Cairo's metro network was greatly expanded in the mid-1990s with the building of Line 2 (red), from Shubra Al Khaimah to
Cairo University, with an extension to
Giza. It is the first line in history to have a tunnel going under the
Nile. The tunnel under the Nile is in internal diameter and was constructed using two Herenknecht bentonite slurry shield
TBMs, which are in diameter. Total project cost was 761 million euros. After the
2011 Egyptian revolution, the station "Mubarak" has been renamed and is now called "Al-Shohadaa" (Arabic for "martyrs"). • October 1996 Shobra - Mubarak (now:"Al-Shohadaa"), • Sept 1998: Mubarak (now:"Al-Shohadaa") - Sadat, • April 19, 1999: Sadat - Cairo University, (including crossing of the Nile) • October 8, 2000: Cairo University - Giza Suburban • January 17, 2005: Omm el Misryeen - Monib ==Connections==
