In the 2016
American Community Survey, 72.3% of working city of Miami residents commuted by driving alone, 8.7% carpooled, 9% used public transportation, and 3.7% walked. About 1.8% used all other forms of transportation, including taxicab, motorcycle, and bicycle. About 4.5% of working city of Miami residents worked at home. In 2015, 19.9% of city of Miami households were without a car, which decreased to 18.6% in 2016. The national average was 8.7 percent in 2016. Miami averaged 1.24 cars per household in 2016, compared to a national average of 1.8 per household.
Expressways and roads Miami's road system is based along the numerical Miami grid where
Flagler Street forms the east–west
baseline and
Miami Avenue forms the north–south
meridian. The corner of Flagler Street and Miami Avenue is in the middle of Downtown in front of the Downtown
Macy's (formerly the
Burdine's headquarters). The Miami grid is primarily numerical so that, for example, all street addresses north of Flagler Street and west of Miami Avenue have "NW" in their address. Because its point of origin is in Downtown, which is close to the coast, the "NW" and "SW" quadrants are much larger than the "SE" and "NE" quadrants. Many roads, especially major ones, are also named (e.g.,
Tamiami Trail/SW 8th St), although, with exceptions, the number is in more common usage among locals. With few exceptions, within this grid north–south roads are designated as Courts, Roads, Avenues or Places (often remembered by their acronym), while east–west roads are streets, Terraces, Drives or occasionally Ways. Major roads in each direction are located at one mile intervals. There are 16
blocks to each mile on north–south avenues, and 10 blocks to each mile on east–west streets. Major north–south avenues generally end in "7" – e.g., 17th, 27th, 37th/Douglas Aves., 57th/Red Rd., 67th/Ludlam, 87th/Galloway, etc., all the way west beyond 177th/Krome Avenue. One prominent exception is 42nd Avenue, LeJeune Road, located at the half-mile point instead. Major east–west streets to the south of Downtown are multiples of 16, though the beginning point of this system is at SW 8th St, one half-mile south of Flagler ("zeroth") Street. Thus, major streets are at 8th St., 24th St./Coral Way, 40th St./Bird, 56th/Miller, 72nd/ Sunset, 88th/N. Kendall, 104th (originally S. Kendall), 120th/Montgomery, 136th/Howard, 152nd/Coral Reef, 168th/Richmond, 184th/Eureka, 200th/Quail Roost, 216th/Hainlin Mill, 232nd/Silver Palm, 248th/Coconut Palm, etc., well into the 300s. Within the grid, odd-numbered addresses are generally on the north or east side, and even-numbered addresses are on the south or west side. All streets and avenues in
Miami-Dade County follow the Miami grid, with a few exceptions, most notably in
Coral Gables,
Hialeah, Coconut Grove and
Miami Beach. One neighborhood,
The Roads, is named as such because its streets run off the Miami grid at a 45-degree angle, and therefore are all named roads.
Miami-Dade County is served by four Interstate Highways (
I-75,
I-95,
I-195,
I-395) and several U.S. Highways including
U.S. Route 1,
U.S. Route 27,
U.S. Route 41, and
U.S. Route 441. Some of the major

Miami Lakes to
Opa-locka Miami has six major
causeways that span over Biscayne Bay connecting the western mainland, with the eastern barrier islands along the Atlantic Ocean. The
Rickenbacker Causeway is the southernmost causeway and connects Brickell to
Virginia Key and
Key Biscayne. The
Venetian Causeway and
MacArthur Causeway connect
Downtown with
South Beach. The
Julia Tuttle Causeway connects
Midtown and
Miami Beach. The
79th Street Causeway connects the
Upper East Side with
North Beach. The northernmost causeway, the
Broad Causeway, is the smallest of Miami's six causeways and connects
North Miami to
Bay Harbor Islands and
Bal Harbour. In 2007, Miami was identified as having the rudest drivers in the United States, the second year in a row to have been cited, in a poll commissioned by automobile club AutoVantage. Miami is also consistently ranked as one of the most dangerous cities in the United States for pedestrians.
Public transportation Public transportation in Miami is operated by
Miami-Dade Transit and
SFRTA, and includes
commuter rail (
Tri-Rail), heavy-rail
rapid transit (
Metrorail), an elevated
people mover (
Metromover), and buses (
Metrobus). Miami has Florida's highest transit ridership as about 17% of Miamians use transit on a daily basis. The average Miami public transit commute on weekdays is 90 minutes, while 39% of public transit riders commute for more than 2 hours a day. The average wait time at a public transit stop or station is 18 minutes, while 37% of riders wait for more than 20 minutes on average every day. The average single trip distance with public transit is , while 38% travel more than in each direction. Miami's heavy-rail rapid transit system,
Metrorail, is an elevated system comprising two lines and 23 stations on a -long line. Metrorail connects the urban western suburbs of
Hialeah,
Medley, and inner-city Miami with suburban
The Roads,
Coconut Grove,
Coral Gables,
South Miami, and urban
Kendall via the central business districts of
Miami International Airport, the
Health District, and Downtown. A free, elevated
people mover,
Metromover, operates 21 stations on three different lines in greater Downtown Miami, with a station at roughly every two blocks of Downtown and Brickell. Several expansion projects are being funded by a transit development sales tax surcharge throughout Miami-Dade County.
Tri-Rail, a commuter rail system operated by the
South Florida Regional Transportation Authority (SFRTA), runs from
Miami International Airport northward to
West Palm Beach, making eighteen stops throughout
Miami-Dade,
Broward, and
Palm Beach counties. The
Miami Intermodal Center is a massive transportation hub servicing
Metrorail,
Amtrak,
Tri-Rail,
Brightline,
Metrobus,
Greyhound Lines,
taxis,
rental cars,
MIA Mover, private automobiles, bicycles and pedestrians adjacent to Miami International Airport. Miami Intermodal Center was completed in 2010, and is serving about 150,000 commuters and travelers in the Miami area. Phase I of
MiamiCentral Station was completed in 2012, and the Tri-Rail part of Phase II was completed in 2015, but the construction of the Amtrak part remains delayed. Two new light rail systems, Baylink and the Miami Streetcar, have been proposed and are currently in the planning stage. BayLink would connect Downtown with
South Beach, and the Miami Streetcar would connect Downtown with
Midtown. Miami is the southern terminus of
Amtrak's Atlantic Coast services, running two lines, the
Silver Meteor and the
Silver Star, both terminating in New York City. The Miami Amtrak Station is located in the suburb of
Hialeah near the
Tri-Rail/Metrorail Station on NW 79 St and NW 38 Ave. Current construction of the
MiamiCentral Station will move all Amtrak operations from its current out-of-the-way location to a centralized location with
Metrorail,
MIA Mover,
Tri-Rail,
Miami International Airport, and the
Miami Intermodal Center all within the same station closer to Downtown. The station was expected to be completed by 2012, but experienced several delays and was later expected to be completed in late 2014, again pushed back to early 2015.
Airports , the nation's 10th-largest airport
Miami International Airport serves as the primary international airport of the Greater Miami Area. One of the busiest international airports in the world because of its centric location, Miami International Airport caters to over 45 million passengers a year. The airport is a major hub and the largest international gateway for
American Airlines. Miami International is the second busiest airport by passenger traffic in Florida, the United States' third-largest international port of entry for foreign air passengers, behind New York's
John F. Kennedy International Airport and
Los Angeles International Airport. The airport's extensive international route network includes non-stop flights to over seventy international cities in North and
South America,
Europe,
Africa,
Asia, and the
Middle East.
Miami-Opa Locka Executive Airport in
Opa-locka and
Miami Executive Airport in an unincorporated area southwest of Miami serve general aviation traffic in the Miami area.
Cycling and walking The city government under former mayor
Manny Diaz took an ambitious stance in support of
bicycling in Miami for both recreation and commuting. In 2010, Miami was ranked as the 44th-most bike-friendly city in the U.S., according to
Bicycling Magazine. A 2011 study by
Walk Score ranked Miami the eighth-most walkable of the 50 largest cities in the U.S.
