Suez Canal

, which followed Wadi Tumilat Ancient west–east canals were built to facilitate travel from the Nile to the Red Sea. One smaller canal is believed to have been constructed under the auspices of Senusret II or Ramesses II. The legendary Sesostris (likely either Pharaoh Senusret II or Senusret III of the Twelfth Dynasty of Egypt (In ancient times, the Red Sea may have reached northward to the Bitter Lakes In his Meteorology, Aristotle (384–322 BCE) wrote: One of their kings tried to make a canal to it (for it would have been of no little advantage to them for the whole region to have become navigable; Sesostris is said to have been the first of the ancient kings to try), but he found that the sea was higher than the land. So he first, and Darius afterwards, stopped making the canal, lest the sea should mix with the river water and spoil it. Strabo wrote that Sesostris started to build a canal, and Pliny the Elder (23/24–79 AD) wrote: 165. Next comes the Tyro tribe and, the harbour of the Daneoi, from which Sesostris, king of Egypt, intended to carry a ship-canal to where the Nile flows into what is known as the Delta; this is a distance of over . Later the Persian king Darius had the same idea, and yet again Ptolemy II, who made a trench wide, deep and about long, as far as the Bitter Lakes. In the 20th century, the northward extension of the later Darius I canal was discovered, extending from Lake Timsah to the Ballah Lakes. This was dated to the Middle Kingdom of Egypt by extrapolating the dates of ancient sites along its course. Recent excavations in Wadi Gawasis may indicate that Egypt's maritime trade started from the Red Sea and did not require a canal. Evidence seems to indicate its existence by the 13th century BCE during the time of Ramesses II. Canals dug by Necho, Darius I and Ptolemy Remnants of an ancient west–east canal through the ancient Egyptian cities of Bubastis, Pi-Ramesses, and Pithom were discovered by Napoleon Bonaparte and his engineers and cartographers in 1799. According to the Histories of the Greek historian Herodotus, about 600 BCE, Necho II undertook to dig a west–east canal through the Wadi Tumilat between Bubastis and Heroopolis, According to Pliny the Elder, Necho's extension to the canal was about , Necho's war with Nebuchadnezzar II most probably prevented the canal's continuation. Necho's project was completed by Darius I of Persia, who ruled over Ancient Egypt after it had been conquered by his predecessor Cambyses II. It may be that by Darius's time a natural in the vicinity of the Egyptian town of Shaluf or Shaloof The canal left the Nile at Bubastis. An inscription on a pillar at Pithom records that in 270 or 269 BCE, it was again reopened, by Ptolemy II Philadelphus. In Arsinoe, In the second half of the 19th century, French cartographers discovered the remnants of an ancient north–south canal past the east side of Lake Timsah and ending near the north end of the Great Bitter Lake. This proved to be the canal made by Darius I, as his stele commemorating its construction was found at the site. (This ancient, second canal may have followed a course along the shoreline of the Red Sea when it once extended north to Lake Timsah. (Modern historians, however, maintain that her ships were burned by the enemy forces of Malichus I.) Cairo to the Red Sea The ancient canal was re-excavated by Roman emperor Trajan in the first century AD, who named it after himself. He reportedly moved its mouth on the Nile further south, at the site of what is now Old Cairo. By the time of the Arab conquest in 641 AD, this canal had fallen out of use. The commander of the Muslim force, Amr ibn al-As, ordered that it be restored so as to improve connections between Egypt and Medina, the Muslim capital at the time. The Muslim canal was excavated further north from Trajan's canal, joining the Nile close to what is now the Sayyida Zaynab neighbourhood of Cairo. The site of the former Roman channel near the Nile was absorbed into the new city of Fustat. The Abbasid caliph al-Mansur is said to have ordered this canal closed in 767 to prevent supplies from reaching Arabian detractors. Conception by Venice The successful 1488 navigation of southern Africa by Bartolomeu Dias opened a direct maritime trading route to India and the Spice Islands, and forever changed the balance of Mediterranean trade. One of the most prominent losers in the new order, as former middlemen, was the former spice trading center of Venice. Despite entering negotiations with Egypt's ruling Mamelukes, the Venetian plan to build the canal was quickly put to rest by the Ottoman conquest of Egypt in 1517, led by Sultan Selim I. Ottoman attempts During the 16th century, the Ottoman Grand Vizier Sokollu Mehmed Pasha attempted to construct a canal connecting the Red Sea and the Mediterranean. This was motivated by a desire to connect Constantinople to the pilgrimage and trade routes of the Indian Ocean, as well as by strategic concerns—as the European presence in the Indian Ocean was growing, Ottoman mercantile and strategic interests were increasingly challenged, and the Sublime Porte was increasingly pressed to assert its position. A navigable canal would allow the Ottoman Navy to connect its Red Sea, Black Sea, and Mediterranean fleets. However, this project was deemed too expensive, and was never completed. Napoleon's discovery of an ancient canal During the French campaign in Egypt and Syria in late 1798, Napoleon expressed interest in finding the remnants of an ancient waterway passage. This culminated in a cadre of archaeologists, scientists, cartographers and engineers scouring northern Egypt. Their findings, recorded in the ''Description de l'Égypte'', include detailed maps that depict the discovery of an ancient canal extending northward from the Red Sea and then westward toward the Nile. After becoming Emperor of France in 1804, Napoleon contemplated the construction of a north–south canal to connect the Mediterranean with the Red Sea. By avoiding the silt-laden Nile, such a canal would be easier to maintain. But the plan was abandoned because of the erroneous belief that the Red Sea was higher than the Mediterranean, and the waterway would thus require the costly and time-consuming construction of locks to operate. This was the result of using fragmentary survey measurements taken during the aforementioned war. As late as 1861, the unnavigable ancient route discovered by Napoleon from Bubastis to the Red Sea still channelled water as far east as Kassassin. ==History of the Suez Canal==

Interim period , northern Gulf of Suez, route to Cairo, 1856 Despite the construction challenges that could have been the result of the alleged difference in sea levels, the idea of finding a shorter route to the east remained alive. In 1830, General Francis Chesney submitted a report to the British government that stated that there was no difference in elevation and that the Suez Canal was feasible, but his report received no further attention. Lieutenant Waghorn established his "Overland Route", which transported post and passengers to India via Egypt. The usefulness of this route for the British Empire was shown when dealing with the Indian Rebellion of 1857, with 5,000 British troops having passed through Egypt. Linant de Bellefonds, a French explorer of Egypt, became chief engineer of Egypt's Public Works. In addition to his normal duties, he surveyed the Isthmus of Suez and made plans for the Suez Canal. French Saint-Simonianists showed an interest in the canal and in 1833, Barthélemy Prosper Enfantin tried to draw Muhammad Ali's attention to the canal but was unsuccessful. Alois Negrelli, the Italian-Austrian railroad pioneer, became interested in the idea in 1836. In 1846, Prosper Enfantin's Société d'Études du Canal de Suez invited a number of experts, among them Robert Stephenson, Negrelli and Paul-Adrien Bourdaloue to study the feasibility of the Suez Canal (with the assistance of Linant de Bellefonds). Bourdaloue's survey of the isthmus was the first generally accepted evidence that there was no practical difference in elevation between the two seas. Britain, however, feared that a canal open to everyone might interfere with its India trade and therefore preferred a connection by train from Alexandria via Cairo to Suez, which Stephenson eventually built. Construction by the Suez Canal Company Preparations (1854–1858) In 1854 and 1856, Ferdinand de Lesseps obtained a concession from Sa'id Pasha, the Khedive of Egypt and Sudan, to create a company to construct a canal open to ships of all nations. The company was to operate the canal for 99 years from its opening. De Lesseps had used his friendly relationship with Sa'id, which he had developed while he was a French diplomat in the 1830s. As stipulated in the concessions, de Lesseps convened the International Commission for the piercing of the isthmus of Suez (''Commission Internationale pour le percement de l'isthme de Suez'') consisting of 13 experts from seven countries, among them John Robinson McClean, later President of the Institution of Civil Engineers in London, and again Negrelli, to examine the plans developed by Linant de Bellefonds, and to advise on the feasibility of and the best route for the canal. After surveys and analyses in Egypt and discussions in Paris on various aspects of the canal, where many of Negrelli's ideas prevailed, the commission produced a unanimous report in December 1856 containing a detailed description of the canal complete with plans and profiles. The Suez Canal Company (Compagnie universelle du canal maritime de Suez) came into being on 15 December 1858. The British government had opposed the project from the outset to its completion. The British, who controlled the Cape Route to India and the Far East, favored the status quo, given that a canal might disrupt their commercial and maritime supremacy. Lord Palmerston, the project's most unwavering foe, confessed in the mid-1850s the real motive behind his opposition: that Britain's commercial and maritime relations would be overthrown by the opening of a new route, open to all nations, and thus deprive his country of its present exclusive advantages. As one of the diplomatic moves against the project when it nevertheless went ahead, it disapproved of the use of "forced labour" for construction of the canal. Involuntary labour on the project ceased, and the viceroy condemned the corvée, halting the project. International opinion was initially skeptical, and shares of the Suez Canal Company did not sell well overseas. Britain, Austria, and Russia did not buy a significant number of shares. With assistance from the Cattaui banking family, and their relationship with James de Rothschild of the French House of Rothschild, bonds and shares were successfully promoted in France and other parts of Europe. All French shares were quickly sold in France. A contemporary British skeptic claimed "One thing is sure... our local merchant community doesn't pay practical attention at all to this grand work, and it is legitimate to doubt that the canal's receipts... could ever be sufficient to recover its maintenance fee. It will never become a large ship's accessible way in any case." Construction (1859–1869) Work started on the shore of the future Port Said on 25 April 1859. The excavation took some 10 years, with forced labour (corvée) being employed until 1864 to dig out the canal. Some sources estimate that over 30,000 people were working on the canal at any given period, that more than 1.5 million people from various countries were employed, and that tens of thousands of labourers died, many of them from cholera and similar epidemics. Estimates of the number of deaths vary widely, with Gamal Abdel Nasser citing 120,000 deaths upon nationalisation of the canal in a 26 July 1956 speech and the company's chief medical officer reporting no higher than 2.49 deaths per thousand in 1866. These were Port Said (1869) and Port Fuad (1925) at the canal's northern entrance by the Mediterranenan, Ismailia (1862) near the middle and north of Lake Timsah, and Port Twefik (1867) at the canal's southern entrance on the Red Sea. Inauguration (17 November 1869) . The canal opened under French control in November 1869. The opening ceremonies began at Port Said on the evening of 15 November, with illuminations, fireworks, and a banquet on the yacht of the Khedive Isma'il Pasha of Egypt and Sudan. The royal guests arrived the following morning: the Emperor Franz Joseph I, the French Empress Eugenie in the Imperial yacht ''L'Aigle, the Crown Prince of Prussia, and Prince Louis of Hesse. Other international guests included the American natural historian H. W. Harkness. In the afternoon there were blessings of the canal with both Muslim and Christian ceremonies, a temporary mosque and church having been built side by side on the beach. In the evening there were more illuminations and fireworks. The Newport'' was involved in an incident that demonstrated some of the problems with the canal. There were suggestions that the depth of parts of the canal at the time of the inauguration were not as great as promised, and that the deepest part of the channel was not always clear, leading to a risk of grounding. Initial difficulties (1869–1871) . Although numerous technical, political, and financial problems had been overcome, the final cost was more than double the original estimate. The Khedive, in particular, was able to overcome initial reservations held by both British and French creditors by enlisting the help of the Sursock family, whose deep connections proved invaluable in securing much international support for the project. After the opening, the Suez Canal Company was in financial difficulties. The remaining works were completed only in 1871, and traffic was below expectations in the first two years. De Lesseps therefore tried to increase revenues by interpreting the kind of net ton referred to in the second concession (tonneau de capacité) as meaning a ship's cargo capacity and not only the theoretical net tonnage of the "Moorsom System" introduced in Britain by the Merchant Shipping Act in 1854. The ensuing commercial and diplomatic activities resulted in the International Commission of Constantinople establishing a specific kind of net tonnage and settling the question of tariffs in its protocol of 18 December 1873. This was the origin of the Suez Canal Net Tonnage and the Suez Canal Special Tonnage Certificate, both of which are still in use today. Growth and reorganisation The canal had an immediate and dramatic effect on world trade. Combined with the American transcontinental railroad completed six months earlier, it allowed the world to be circled in record time. It played an important role in increasing European colonization of Africa. The construction of the canal was one of the reasons for the Panic of 1873 in Great Britain, because goods from the Far East had, until then, been carried in sailing vessels around the Cape of Good Hope and stored in British warehouses. An inability to pay his bank debts led Said Pasha's successor, Isma'il Pasha, in 1875 to sell his 44% share in the canal for £4,000,000 ($19.2 million), equivalent to £432 million to £456 million ($540 million to $570 million) in 2019, to the government of the United Kingdom. French shareholders still held the majority. Local unrest caused the British to invade Egypt in 1882 and take full control, although nominally Egypt remained part of the Ottoman Empire. The British representative from 1883 to 1907 was Evelyn Baring, 1st Earl of Cromer, who reorganized and modernized the government and suppressed rebellions and corruption, thereby facilitating increased traffic on the canal. The European Mediterranean countries in particular benefited economically from the Suez Canal, as they now had much faster connections to Asia and East Africa than the North and West European maritime trading nations such as Great Britain, the Netherlands or Germany. The biggest beneficiary in the Mediterranean was Austria-Hungary, which had participated in the planning and construction of the canal. The largest Austrian maritime trading company, Österreichischer Lloyd, experienced rapid expansion after the canal was completed, as did the port city of Trieste, then an Austrian possession. The company was a partner in the Compagnie Universelle du Canal de Suez, whose vice-president was the Lloyd co-founder Pasquale Revoltella. In 1900, a dredging trial was held by the Suez Canal Company to determine which ship would assist in the widening and deepening of the canal. The Hercules dredged deposits of granite and limestone, but it was determined at the end of the trial that the Hercules would not be used for the dredging of the Suez Canal. Under the Anglo-Egyptian Treaty of 1936, the UK retained control over the canal. With outbreak of World War II the canal was again strategically important; Italo-German attempts to capture it were repulsed during the North Africa Campaign, which ensured the canal remained closed to Axis shipping. After the war the British Army continued to maintain a large garrison of some 70,000 troops in the Suez Canal Zone. Suez Crisis on Port Said, 5 November 1956. In 1951, Egypt repudiated the 1936 treaty with United Kingdom. In October 1954, the United Kingdom tentatively agreed to remove its troops from the Canal Zone. Because of Egyptian overtures towards the Soviet Union, both the United Kingdom and the United States withdrew their pledge to financially support construction of the Aswan Dam. Egyptian President Gamal Abdel Nasser responded by nationalising the canal on 26 July 1956 and transferring it to the Suez Canal Authority, intending to finance the dam project using revenue from the canal. On the same day that the canal was nationalised, Nasser also closed the Straits of Tiran to all Israeli ships. This led to the Suez Crisis in which the UK, France, and Israel invaded Egypt's Sinai. According to the pre-agreed war plans under the Protocol of Sèvres, Israel invaded the Sinai Peninsula on 29 October, forcing Egypt to engage them militarily, and allowing the Anglo-French partnership to declare the resultant fighting a threat to stability in the Middle East and enter the war – officially to separate the two forces but in reality to regain the Canal and bring down the Nasser government. To save the British from what he thought was a disastrous action and to stop the war from a possible escalation, Canadian Secretary of State for External Affairs Lester B. Pearson proposed the creation of the first United Nations peacekeeping force to ensure access to the canal for all and an Israeli withdrawal from the Sinai Peninsula. On 4 November 1956, a majority at the United Nations voted for Pearson's peacekeeping resolution, which mandated the UN peacekeepers to stay in Sinai unless both Egypt and Israel agreed to their withdrawal. The United States backed this proposal by putting pressure on the British government through the selling of sterling, which would cause it to depreciate. The UK then called a ceasefire, and later agreed to withdraw its troops by the end of the year. Pearson was later awarded the Nobel Peace Prize. As a result of damage and ships sunk under orders from Nasser, the canal was closed from November 1956 to April 1957, when it was cleared with UN assistance. A UN force (UNEF) was established to maintain the free navigability of the canal, and peace in the Sinai Peninsula. Arab–Israeli wars of 1967 and 1973 /Magach tank crosses the Suez Canal, 1973 After the 1948 Arab–Israeli War, Egypt closed the Canal to Israeli shipping, despite UN Security Council resolutions from 1949 and 1951 urging it not to, on the grounds that hostilities had ended with the 1949 armistice agreement. On 16 May 1967, Nasser ordered UNEF peacekeeping forces out of the Sinai Peninsula, including the Suez Canal area. Egyptian troops were sent into Sinai to take their place. On 21 May, Israel protested Nasser's order to close the Straits of Tiran to Israeli trade. After the 1967 Six-Day War, Israeli forces occupied the Sinai Peninsula and the Egyptian-administered Gaza Strip, including the entire east bank of the Suez Canal. In the following years, the tensions between Egypt and Israel intensified and from 1967 until August 1970, the War of Attrition took place as the then Egyptian president, Gamal Abdel Nasser, tried to retake the territories occupied by Israel during the conflict. The fighting ceased after the death of Nasser on 28 September 1970. After this conflict there were no changes in the distribution of territory, but the underlying tensions persisted. Unwilling to allow the Israelis to use the canal, Egypt imposed a blockade which closed the canal to all shipping immediately after the beginning of the Six-Day War. The canal remained blocked for eight years. There was no anticipation of this event and consequently fifteen cargo ships, known as the "Yellow Fleet", were trapped in the canal, and remained there until its reopening in 1975. On 6 October 1973, during the start of the Yom Kippur War, the Canal was the scene of Operation Badr, in which the Egyptian army crossed into Israeli-occupied Sinai. Much wreckage from this conflict remains visible along the canal's edges. On 22 October 1973, Israeli forces counter-attacked by crossing the Suez Canal into Egypt and advancing towards Suez City, where they remained until after Israel and Egypt signed on 18 January 1974, an agreement, commonly known as Sinai I, with the official name of Sinai Separation of Forces Agreement, which included a withdrawal of Israeli forces from the western side of the Suez Canal. Mine clearing operations (1974–1975) and Minister of Defense Ahmed Ismail in the re-opening of Suez Canal, 5 June 1975 After the Yom Kippur War, the United States initiated Operation Nimbus Moon. The amphibious assault ship USS Inchon (LPH-12) was sent to the Canal, carrying 12 RH-53D minesweeping helicopters of Helicopter Mine Countermeasures Squadron 12. These partly cleared the canal between May and December 1974. It was relieved by the LST USS Barnstable County (LST1197). The British Royal Navy initiated Operation Rheostat and Task Group 65.2 provided for Operation Rheostat One (six months in 1974), the minehunters HMS Maxton, HMS Bossington, and HMS Wilton, the Fleet Clearance Diving Team (FCDT) and HMS Abdiel, a practice minelayer/MCMV support ship; and for Operation Rheostat Two (six months in 1975) the minehunters HMS Hubberston and HMS Sheraton, and HMS Abdiel. When the Canal Clearance Operations were completed, the canal and its lakes were considered 99% clear of mines. The canal was then reopened by Egyptian President Anwar Sadat aboard an Egyptian destroyer, which led the first convoy northbound to Port Said in 1975, at his side stood the Iranian Crown Prince Reza Pahlavi. UN presence The UNEF mandate expired in 1979. Despite the efforts of the United States, Israel, Egypt, and others to obtain an extension of the UN role in observing the peace between Israel and Egypt, as called for under the Egypt–Israel peace treaty of 1979, the mandate could not be extended because of the veto by the Soviet Union in the UN Security Council, at the request of Syria. Accordingly, negotiations for a new observer force in the Sinai produced the Multinational Force and Observers (MFO), stationed in Sinai in 1981 in coordination with a phased Israeli withdrawal. The MFO remains active under agreements between the United States, Israel, Egypt, and other nations. Bypass expansion In 2014, months after taking office as President of Egypt, Abdel Fattah el-Sisi ordered the expansion of the Ballah Bypass from wide to wide for . The project was called the New Suez Canal, as it allows ships to transit the canal in both directions simultaneously. The project cost more than LE 59.4 billion (US$9 billion) and was completed within a year. Sisi declared the expanded channel open to business in a ceremony on 6 August 2015. == Incidents ==

In 2004, the canal was closed for three days when the oil tanker Tropic Brilliance became stuck. On 18 October 2017, the OOCL Japan ran aground causing an obstruction which blocked the canal for a few hours. the Suez Canal was blocked in both directions by ultra-large Evergreen G-class container ship Ever Given. The ship, operated by Evergreen Marine, was en route from Malaysia to the Netherlands when it ran aground after strong winds allegedly blew the ship off course. When the incident began, many economists and trade experts commented on the effects of the obstruction if not resolved quickly, citing how important the Suez was to global trade; the incident was likely to drastically affect the global economy because of the trapped goods scheduled to go through the canal. Among those goods, oil shipments were the most affected in the immediate aftermath, due to a significant number still blocked with no other way to reach their destination. Ever Given was re-floated on 29 March. Within a few hours, cargo traffic resumed, slowly resolving the backlog of around 450 ships. The first ship to pass through the canal after Ever Given's recovery was YM Wish, a Hong Kong-based cargo ship. On 2 April 2021, Usama Rabie, chairman of the Suez Canal Authority of Egypt, said that the damage caused by the blockage of the canal could reach about $1 billion. Rabie also revealed that after the Suez Canal resumed navigation, as of noon on 31 March 285 cargo ships had passed through the canal smoothly. He said that the remaining 175 freighters waiting to pass through the canal would all pass by 2 April. After the incident, the Egyptian government announced that they would be widening the narrower parts of the canal. On 9 September 2021, the canal was briefly blocked again by MV Coral Crystal. However, this ship was freed within 15 minutes, presenting minimal disruption to other convoys. 2023 grounding On 25 May 2023, a Hong Kong-flagged cargo ship, MV Xin Hai Tong 23, was grounded near the southern end of the canal, but it was refloated by tugboats in less than a day. == Layout and operation ==

When built, the canal was long and deep. After several enlargements, it is long, deep and wide. It consists of the northern access channel of , the canal itself of and the southern access channel of . The so-called New Suez Canal, functional since 6 August 2015, currently has a new parallel canal in the middle part, with its length over . The current parameters of the Suez Canal, including both individual canals of the parallel section are: depth and width at least (that width measured at of depth). Capacity The canal allows passage of ships up to draft or 240,000 deadweight tons and up to a height of above water level and a maximum beam of under certain conditions. Navigation Ships approaching the canal from the sea are expected to radio the harbour when they are within of the Fairway Buoy near Port Said. The canal has no locks because of the flat terrain, and the minor sea level difference between each end is inconsequential for shipping. As the canal has no sea surge gates, the ports at the ends would be subject to the sudden impact of tsunamis from the Mediterranean Sea and Red Sea, according to a 2012 article in the Journal of Coastal Research. There is one shipping lane with passing areas in Ballah-Bypass near El Qantara and in the Great Bitter Lake. On a typical day, three convoys transit the canal, two southbound and one northbound. The passage takes between 11 and 16 hours at a speed of around . The low speed helps prevent erosion of the banks by ships' wakes. By 1955, about two-thirds of Europe's oil passed through the canal. Around 8% of world sea trade is carried via the canal. In 2008, 21,415 vessels passed through the canal and the receipts totalled $5.381 billion, File:SuezCanal ElBallah.JPG|Ships moored at El Ballah during transit File:USS America (CV-66) in the Suez canal 1981.jpg|, an American aircraft carrier in the Suez Canal File:SuezCanal4 byDanielCsorfoly.JPG|Container ship Hanjin Kaohsiung transiting the Suez Canal Operation Before August 2015, the canal was too narrow for free two-way traffic, so ships had to pass in convoys and use bypasses. The bypasses were out of (40%). From north to south, they are Port Said bypass (entrances) , Ballah bypass & anchorage , Timsah bypass , and the Deversoir bypass (northern end of the Great Bitter Lake) . The bypasses were completed in 1980. Typically, it would take a ship 12 to 16 hours to transit the canal. The canal's 24-hour capacity was about 76 standard ships. In August 2014, Egypt chose a consortium that includes the Egyptian army and global engineering firm Dar Al-Handasah to develop an international industrial and logistics hub in the Suez Canal area, and began the construction of a new canal section from combined with expansion and deep digging of the other of the canal. This has allowed navigation in both directions simultaneously in the central section of the canal. These extensions were formally opened on 6 August 2015 by President Al-Sisi. File:Capesize bulk carrier at Suez Canal Bridge.JPG|Post-deepening, a capesize bulk carrier approaches the Friendship Bridge File:Bittersee Suezkanal.jpg|Northbound convoy waits in the Great Bitter Lake as southbound convoy passes, October 2014 Convoy sailing Since the canal does not cater to unregulated two-way traffic, all ships transit in convoys on regular times, scheduled on a 24-hour basis. Each day, a single northbound convoy starts at 04:00 EET from Suez. At dual lane sections, the convoy uses the eastern route. Synchronised with this convoy's passage is the southbound convoy. It starts at 03:30 EET from Port Said and so passes the Northbound convoy in the two-lane section. Canal crossings From north to south, the crossings are: • The El Nasr pontoon bridge (), connecting Port Said to Port Fuad. Opened in 2016, length. • The Abanoub Gerges pontoon bridge (), north of the Suez Canal Bridge • The Suez Canal Bridge (), also called the Egyptian-Japanese Friendship Bridge, a high-level road bridge at El Qantara. In Arabic, al qantara means "arch". Opened in 2001, it has a clearance over the canal and was built with assistance from the Japanese government and by Kajima. • El Ferdan Railway Bridge () north of Ismailia () was completed in 2001 and is the longest swing-span bridge in the world, with a span of 340 m (1100 ft). The previous bridge was destroyed in 1967 during the Arab-Israeli conflict. The current bridge is no longer functional due to the expansion of the Suez Canal, as the parallel shipping lane completed in 2015 just east of the bridge lacks a structure spanning it. However, plans surfaced in 2017 to build a new bridge spanning the parallel canal and converting the old single track railway on the Ferdan to a double track, which as of October 2023, were near completion. • The Ahmed el-Mansy pontoon bridge (), a pair of pontoons bridging both channels • The Taha Zaki Abdullah pontoon bridge (), a pair of pontoons bridging both channels • Pipelines taking fresh water under the canal to Sinai, about north of Suez, at . • Ahmed Hamdi Tunnel () south of the Great Bitter Lake () was built in 1983. Because of leakage problems, a new water-tight tunnel was built inside the old one from 1992 to 1995. • The Ahmed Omar Shabrawy pontoon bridge () • The Suez Canal overhead powerline crossing () was built in 1999. A railway on the west bank runs parallel to the canal for its entire length. The five pontoon bridges were opened between 2016 and 2019. They are designed to be movable, and can be completely rotated against the banks of the canal to allow shipping through, or else individual sections can be moved to create a narrower channel. Six new tunnels for cars and trains are also planned across the canal. Currently the Ahmed Hamdi is the only tunnel connecting Suez to the Sinai. == Economic impact ==

, one of the economic hubs in the 19th century Economically, after its completion, the Suez Canal benefited primarily the sea trading powers of the Mediterranean countries, which now had much faster connections to the Near and Far East than the North and West European sea trading nations such as Great Britain or Germany. The main Habsburg trading port of Trieste with its direct connections to Central Europe experienced a meteoric rise at that time. The time saved in the 19th century for an assumed steamship trip to Bombay from Brindisi and Trieste was 37 days, from Genoa 32, from Marseille 31, from Bordeaux, Liverpool, London, Amsterdam and Hamburg 24 days. At that time, it was also necessary to consider whether the goods to be transported could bear the costly canal tariff. This led to a rapid growth of Mediterranean ports with their land routes to Central and Eastern Europe. According to today's information from the shipping companies, the route from Singapore to Rotterdam through the Suez Canal will be shortened by and thus by nine days compared to the route around Africa. As a result, liner services between Asia and Europe save 44 per cent CO2 (carbon dioxide) thanks to this shorter route. The Suez Canal has a correspondingly important role in the connection between East Africa and the Mediterranean region. In the 20th century, trade through the Suez Canal came to a standstill several times, due to the two world wars and the Suez Canal crisis. Many trade flows were also shifted away from the Mediterranean ports towards Northern European terminals, such as Hamburg and Rotterdam. Only after the end of the Cold War, the growth in European economic integration, the consideration of CO2 emission and the Chinese Silk Road Initiative, are Mediterranean ports such as Piraeus and Trieste again at the focus of growth and investment. The Suez Canal set a new record with annual revenue of $9.4 billion in USD for the fiscal year that ended 30 June 2023. Attacks by Houthi rebels on shipping vessels off the coast of Yemen caused monthly losses of $800 million, according to Egypt's President Sisi. == Alternative routes ==

Before the canal's opening in 1869, goods were sometimes offloaded from ships and carried overland between the Mediterranean and the Red Sea. Cape Agulhas The main alternative is around Cape Agulhas, the southernmost point of Africa, commonly referred to as the Cape of Good Hope route. This was the only sea route before the canal was constructed, and when the canal was closed. It is still the only route for ships that are too large for the canal. In the early 21st century, the Suez Canal has suffered from diminished traffic due to piracy in Somalia, with many shipping companies choosing to take the long route instead. Between 2008 and 2010, it is estimated that the canal lost 10% of traffic due to the threat of piracy, and another 10% due to the 2008 financial crisis. An oil tanker going from Saudi Arabia to the United States has farther to go when taking the route south of Africa rather than the canal. Northern Sea Route (blue) and an alternative route through Suez Canal (red) In recent years, the shrinking Arctic sea ice has made the Northern Sea Route feasible for commercial cargo ships between Europe and East Asia during a six-to-eight-week window in the summer months, shortening the voyage by thousands of kilometres compared to that through the Suez Canal. According to polar climate researchers, as the extent of the Arctic summer ice pack recedes the route will become passable without the help of icebreakers for a greater period each summer. The Bremen-based Beluga Group claimed in 2009 to be the first Western company to attempt using the Northern Sea Route without assistance from icebreakers, cutting off the journey between Ulsan, Korea and Rotterdam, the Netherlands. Cape Horn Sailing ships, such as the windjammers in the heyday of the Great Grain Race between Australia and Europe during the 1930s, often preferred the Cape Horn route when going to Europe, due to prevalent wind directions, even though it is slightly longer from Sydney to Europe this way than past Cape Agulhas. Negev desert railway In February 2012, Israel announced its intention to construct a railway between the Mediterranean and Eilat through the Negev desert to compete with the canal. By 2019, the project had been put on indefinite hold. Iraq–Europe Development Road First envisioned in the 1980s, an ongoing infrastructure project nicknamed the Dry Canal seeks to turn Iraq into an international transit hub. The project includes creating corridors that link the southern coastal province of Basra and the Grand Faw Port and several other provinces of Iraq with Turkey and further extend into Europe. Once finished, it will serve as an alternative route for international freight traffic. It was first introduced in the 1980s, but domestic issues, sanctions and wars hindered its implementation. Recent improvements in security and economic growth have allowed Iraq to revive the project, and since 2023, the country has made significant strides in implementing the project. In 2025, a pilot operation designed to test the feasibility of the project was conducted; a fully inland operation beginning from Poland and traversing through Turkey and Iraq and reaching its destination in the UAE. According to the operator, the journey was completed securely in under a week, significantly less than a multimodal operation via the Red Sea, which would have (under normal circumstances) taken 21 days. == Environmental impact ==

The opening of the canal created the first salt-water passage between the Mediterranean Sea and the Red Sea. Although the Red Sea is about higher than the eastern Mediterranean, the current between the Mediterranean and the middle of the canal at the Bitter Lakes flows north in winter and south in summer. The current south of the Bitter Lakes is tidal, varying with the tide at Suez. The Red Sea is generally saltier and less nutrient-rich than the Mediterranean, so that Erythrean species will often do well in the 'milder' eastern Mediterranean environment. To the contrary very few Mediterranean species have been able to settle in the 'harsher' conditions of the Red Sea. The dominant, south to north, migratory passage across the canal is often called Lessepsian migration (after Ferdinand de Lesseps) or "Erythrean invasion". The recent construction by the Egyptian government of a major canal extension – allowing for two-way traffic in the central section of the canal and finally implemented in 2015 – raised concerns from marine biologists, who fear that it will enhance the arrival of Red Sea species in the Mediterranean. Exotic species from the Indo-Pacific Ocean and introduced into the Mediterranean via the canal since the 1880s have become a significant component of the Mediterranean ecosystem. They already impact its ecology, endangering some local and endemic species. Since the piercing of the canal, over a thousand species from the Red Sea—plankton, seaweeds, invertebrates, fishes—have been recorded in the Mediterranean, and many others will clearly follow. The resulting change in biodiversity is without precedent in human memory and is accelerating: a long-term cross-Basin survey engaged by the Mediterranean Science Commission recently documented that in the first twenty years of this century more exotic fish species from the Indian Ocean had reached the Mediterranean than during the entire 20th century. Historically, the construction of the canal was preceded by cutting a small fresh-water canal called Sweet Water Canal from the Nile delta along Wadi Tumilat to the future canal, with a southern branch to Suez and a northern branch to Port Said. Completed in 1863, these brought fresh water to a previously arid area, initially for canal construction, and subsequently facilitating growth of agriculture and settlements along the canal. However the Aswan High Dam construction across the Nile, which started operating in 1968, much reduced the inflow of freshwater and cut all natural nutrient-rich silt entering the eastern Mediterranean at the Nile Delta. == Suez Canal Economic Zone ==

The Suez Canal Economic Zone, sometimes shortened to SCZONE, describes the set of locations neighbouring the canal where customs rates have been reduced to zero in order to attract investment. The zone comprises over within the governorates of Port Said, Ismailia and Suez. Projects in the zone are collectively described as the Suez Canal Area Development Project (SCADP). The plan focuses on development of East Port Said and the port of Ain Sokhna, and hopes to extend to four more ports at West Port Said, El-Adabiya, Arish and El Tor. The zone incorporates the four "Qualifying Industrial Zones" at Port Said, Ismailia and Suez, a 1996 American initiative to encourage economic ties between Israel and its neighbours. == See also ==
