The award-winning Cairo Metro Al Thawra Line III is a main line in Greater Cairo’s mass transit system, with the line designed to eventually serve the Heliopolis and Cairo International Airport. The line will meet enormous transportation demands along its route, reduce traffic density and act as the first transversal line linking east and west Cairo. Dar provided the detailed design (architectural, civil, structural, and electromechanical) of the elevated section of the line as well as the line’s heavy maintenance depot.

For the Cairo Metro Line III, Dar prepared the detailed design (under BIM management) of a 7.5-km-long line, extending from El Nozha District to Cairo Ring Road, including six stations, one depot for heavy and light maintenance with 32 buildings, and all related infrastructure and electromechanical services.
The alignment includes an elevated viaduct composed of a composite system (PSC girders/RC slab) with spans ranging from 30 to 40 m each; six elevated stations, comprising five typical twin-track and twin-platform elevated stations and one 3-track twin-platform terminal elevated station with shunting tracks; and one depot for heavy and light maintenance (workshop) with 32 buildings.
The scope also covered preparing and supervising a hydrogeological investigation, estimating long-term groundwater rise, and designing subsurface drainage networks for various elements of the project.
Dar was also involved in the 750 Vdc metro traction power system, the metro stray current systems and the metro’s electromagnetic compatibility (EMC).
In 2021, the project was named ENR’s Best Global Project for Rail and Transit.
