Salah Salem Tunnels

One of two new tunnels constructed in the district of Nasr City with a chief objective of converting the main road to Cairo International Airports into a highway with no traffic light signals. The project also comprised three flyovers.

It is composed of a four-lane tunnel of 11 m in width and 1,750 m in length (a 990 m open section and 760 m closed section with 5 m clear height), having two entrances and two outlets. CFA piles (0.7 m in diameter) and a U-shaped reinforced concrete section were used in the construction of the open sections while the closed sections were constructed using diaphragm walls (0.8 m in thickness) and a reinforced concrete slab system.
