Nigeria to begin work on 38-km Lagos bridge this year

23 March 2017

The government of Lagos State has announced that a 38-km, four-lane road bridge is to be built across the Lagos lagoon to ease congestion on crossings between Lagos Island and the rest of the city.

Work on the $2.7bn Fourth Mainland Bridge is expected to begin this year, once agreement has been reached with those Lagos residents whose homes will have to be demolished to make room for the scheme

The project is to be procured as a build, operate and transfer model, although the length of the concession has not been decided.

Lagos Island lies to the west of the main city, and the three existing crossings provide a direct east–west link to it. The fourth bridge will be situated to the east of the island and will provide a north–south link between Baiyeku and Langbasa over the Lagos lagoon.

The bridge has been under discussion since 2003. A concept design for the project was produced by Nigerian architect and urban planner NLÉ. It has produced a concept design for a two-level bridge that would be part of a ring road around the city, providing alternative traffic routes from Lekki to Ikorodu, Ikeja to Ajah, relieving the Third Mainland bridge of its overstretched capacity.”

At 38km long, the bridge will be the longest in Africa. The present holder, the 6 October Bridge over the Nile in Cairo is 20.5km and Lagos’ Third Mainland Bridge in 10.5km long.
