Nigeria to begin work on 38km Lagos bridge this year

The government of Lagos State has announced that a 38km, 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. It is estimated that between 800 and 3,000 dwellings, most of them in informal settlements, will be affected.

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 would be the longest in Africa

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.

NLÉ comments on its website: "The 2 level bridge will not only function as a means for vehicular traffic on its upper level, it will stimulate and accommodate pedestrian, social, commercial and cultural interactions on it’s lower level – ‘Lagos Life’ – with its tropical environment and intimate street level exchanges.

"The Fourth Mainland Bridge in conjunction with existing road networks would establish a primary ring road around Lagos. This ring road will provide alternative traffic routes from Lekki to Ikorodu, Ikeja to Ajah, relieving the Third Mainland bridge of its overstretched capacity."

NLÉ’s 2008 plan would relieve Lagos’ legendary congestion with a grand bypass

If the bridge is 38km long, it 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.

  1. This is a welcome development and the solution to the one-city-state’s historical traffic nightmare. So long it is Lagos, consider it done.

  2. There is a big silence in the construction industry for a long time regarding the loss owing to frauds,that too in audited Government constructions.It was upwards of US $ 4 Trillion per year in 2008 according to Transparency Internationals.10-30% of the project costs.The combined GDPs of Brazil,Russia,South Africa & Saudi Arabia.US $ 1.50 per head per day of the entire world population.

    What is required is simple.All Government constructions to be audited by construction professionals and there should be a union for them.That is what suggested by GOPAC in their Position Paper of 2015.

    Yet, no University in the world is smart or competent enough to start a Masters Course on Construction Auditing for Construction Professional for the first time.This has a commercial potential of around 500,000 such auditors per year.
