Context
The existing bridge, which links Bonabéri to Douala, was built in the 1950s. Despite recent restoration works, the structure has become obsolete and undersized, generating important traffic problems. The new bridge will secure and improve the traffic flow on this critical roadway for the Cameroonian economy.

Awarded to a joint venture that includes Soletanche Bachy, the design-build project involves a gently curved 760 metre long structure comprising a six-lane road deck and a twin-track railway deck. The decks, with 135 metre spans, are made up of arch segments cast in place and will constitute a technical benchmark.
The two decks rest on five single-beam piers set in the river. They are supported by fifty 2.5 metre diameter injected piles anchored at a depth of nearly 70 metres. The land foundations, with a depth of about 45 metres, will consist of forty 1.5 metre diameter piles.
