Lagos Unveils Ambitious Underwater Tunnel to Transform Coastal Connectivity

Lagos State is set to redefine infrastructure development on the continent with plans to construct Africa’s first underwater road tunnel beneath the Lagos Lagoon, a bold project expected to significantly reshape transportation and trade along Nigeria’s coastal corridor.

The proposed tunnel, measuring about 2.9 kilometres, will run beneath the lagoon to connect Ahmadu Bello Way on Victoria Island to Snake Island, with further extension toward Badagry.

When completed, it will serve as a strategic link between two major national road networks, the Lagos-Calabar Coastal Highway and the Sokoto-Badagry Superhighway, creating a seamless route across regions.

Beyond its engineering significance, the tunnel is projected to ease the persistent traffic congestion that has long plagued Lagos, especially in key commercial and commuter zones.

By providing an alternative route beneath the lagoon, authorities expect smoother vehicular movement, reduced travel time, and improved access to emerging economic hubs along the corridor.

The project will be executed under a Public-Private Partnership (PPP) arrangement, reflecting a growing reliance on private sector expertise and funding to deliver large-scale infrastructure. Officials say this model will accelerate delivery while ensuring long-term sustainability and efficient management.

Once operational, the underwater tunnel is expected to boost inter-regional trade, enhance logistics efficiency, and strengthen Lagos’ position as a leading economic gateway in West Africa.

It also places the state, and the wider South-West region, at the forefront of innovative urban and transport solutions on the African continent.

The initiative marks a historic step in Nigeria’s infrastructure journey, signaling a shift toward more ambitious, future-focused projects designed to support rapid urban growth and regional integration.
