Our Egis teams are working with the company in charge of the future bridge that will link Cocody to the Plateau in Abidjan, carrying out the External Control of the studies, as well as participating in the execution studies, accompanied by technical assistance.
The Cocody Bridge, a link between the eastern suburbs and the capital of the Côte d'Ivoire
Every day, 150,000 vehicles use the Indénié crossroads, located at the end of the Cocody bay. As the main place of automobile traffic in the agglomeration, its capacity is globally exceeded every day during rush hours. The future Cocody bridge aims to provide a link between Bingerville - Cocody - Plateau, avoiding the Indénié crossroads. This structure will provide a link between Saint Paul's Cathedral and will allow vehicles, pedestrians and cyclists to cross the Ebrié Lagoon in Abidjan from east to west. Eventually, no less than 35,000 vehicles will cross the bridge daily.
This mixed bridge, 630 m long and more than 25 m wide, includes a 200 m cable-stayed span on the main bridge, crossing the bay. A 258 m long VIPP (post-tensioned independent span viaduct) access viaduct, which is a continuation of this bridge, will join the Boulevard de France to the east. To the west, an access ramp will link the main bridge with the Boulevard de Gaulle.
A 100 m high pylon
With its 100 m high pylon and 200 m cable-stayed main span, the main structure will be one of the largest bridges in Africa. It has a single layer of 11 stays at the front of the tower, and two layers of 4 stays at the back. At the front, the stays are anchored every 15 m in the deck. At the rear, the stays are anchored in a hollow abutment (C9) which allows the lifting forces of the retaining stays to be taken up. The single tower of the main bridge, made of pre-stressed concrete, is boomerang-shaped, and in the shape of an inverted Y depending on whether it is viewed from the front or the side. The deck is over 25 m wide and has a mixed steel-concrete box structure.
The project was commissioned by the Ministry of Equipment and Road Maintenance (MEER) of Côte d'Ivoire, with architect Pierre Fakhoury and the Arcadis engineering firm as project managers. LCI, Tec4 and Yooshin are in charge of the control mission.
Our Egis teams are carrying out 3 missions on behalf of the Chinese construction company CRBC:
- The External Control of the Execution Studies,
- Technical Assistance
- Participation in the execution studies (pylons, abutments, foundations)
