Abidjan first metro line

Abidjian - Ivory Coast
Layout study and preliminary design
    PPP consortium including Bouygues TP
    Rotem for the Ministry of Transport of Ivory Coast
    Abidjan - Ivory Coast

    Type of services

    Abidjan Metro Line 1 is a surface train 37 km long spreading from North to South and crossing the Abidjan lagoon. The line will serve 20 new stations. 2 intermediate terminus stations will allow to operate the central section of the line with a double frequency.


    The layout uses a narrow urban corridor twinning with the freight SITARAIL line, which implied numerous retaining walls and overpasses.

    The construction has been awarded to a consortium led by Bouygues TP under a PPP scheme.

    The assignment consists in providing a layout study, then a Preliminary and a Detailed responding to the requirements of the Ministry of Transportation, and defining a bankable project for a PPP realization.

    The program and the studies have been optimized to that purpose. For example, one intermediate step consisted in analyzing 3 various infrastructure scenarios, corresponding to 3 tariff scenarios and thus 3 passenger traffic scenarios.


    The full layout, civil works and stations were studied :

    • Main track layout study, and its impact on SITARAIL infrastructures,
    • Earthworks,
    • Geotechnical studies,
    • Hydraulic studies,
    • Bridges : underpasses, overpasses, footbridges for public crossings and at stations,
    • Stations (platforms, buildings, Civil works and systems integration).
