Cairo Metro Line 3
		

				

				

				

							
Project Overview:
The Greater Cairo Metro Line 3 is a monumental infrastructure project transforming the city’s transportation network. Spanning 41.2 km and encompassing 34 stations (21 underground, 2 surface, and 11 elevated), Line 3 is a critical artery connecting Imbaba and Mohandessin, passing under the Nile to Zamalek Island, then extending through Attaba, Abbassia, Cairo Stadium, Heliopolis, Alf Maskan, Shams Club, and culminating at Adly Mansour (10th Station). This line provides crucial interconnections with other transportation modes:
  • Line 1 at Nasser Station
  • Line 2 at Attaba and Cairo University stations
  • The electric train at Adly Mansour Station
  • The East Nile Monorail at the Stadium Station
  • The West Nile Monorail at Wadi El Nil Station
The project was implemented in four distinct phases:
  • Phase 1 (Attaba/Abbassia): 4.4 km, 5 underground stations, inaugurated in 2012.
  • Phase 2 (Abbassia/Al-Ahram): 7.7 km, 4 underground stations, inaugurated in 2014.
  • Phase 3 (Al-Attaba – Kit Kat – Rod El Farag – Cairo University): 17.7 km, 15 stations (8 underground, 5 elevated, 2 surface), opened in 2024.
  • Phase 4 (Haroun – Adly Mansour): 11.5 km, 10 stations (4 underground, 6 elevated), opened in 2019 and 2020 (in two parts). This phase also included the construction of the largest maintenance workshop in the Middle East, covering 65 acres.
This expansive project significantly enhances Cairo’s public transportation capacity, reduces traffic congestion, and promotes sustainable urban development.

ECPC’s Scope of Work:
ECPC played a vital role in the construction of Cairo Metro Line 3, acting as the sole producer of tunnel segments for all 21 underground stations.
ECPC supplied 23,118 meters of segments, totaling 123,296 precast segments (15,412 rings with a diameter of 8,500mm).
In addition, ECPC provided 848 prestressed beams—a first for Egypt—for the 6 elevated viaduct stations. These beams have an average span of 30 to 40 meters and weigh between 75 and 120 tons.
