The 4th Mainland Bridge is a 38 km long bridge set for construction by the Lagos State Government, Nigeria. The bridge cuts across Lekki, Langbasa, and Baiyeiku towns along the shoreline of the Lagos Lagoon estuaries, further running through Igbogbo River Basin and crossing the Lagos Lagoon estuaries to Itamaga Area in Ikorodu. It then crosses the Itoikin road and the Ikorodu – Sagamu Road to connect Isawo inward Lagos Ibadan Expressway at the Ojodu Berger axis.

The bridge is a four-lane dual carriageway, each comprising of 3 lanes and 2 meters hard shoulder on each side. It will also have 9 interchanges to facilitate effective interconnectivity between different parts of the State, in addition to 3 toll plazas, 4.5 km Lagoon Bridge and an eco-friendly environment amongst other features.

As per the design, the future Fourth Mainland Bridge will have a generous median to allow for both future carriageway expansion and light rail/BRT lane. Upon completion, the facility will be the longest of its kind in the whole of Africa.

Benefits of the 4th Mainland Bridge

The 4th Mainland Bridge will connect people and improve their natural flow in large numbers through a reorganization of vehicular, waterways, and pedestrian modes of transportation. It will also serve as a means for vehicular traffic on its upper level, and accommodate pedestrian, social, commercial, and cultural interactions on its lower level.

Additionally, in conjunction with existing road networks, it will establish a primary ring road around Lagos, which is expected to provide alternative traffic routes from Lekki to Ikorodu, Ikeja to Ajah, relieving the 3rd Mainland Bridge of its overstretched capacity.

The idea for the construction of the 4th Mainland Bridge was conceptualized by the government of Lagos under Bola Ahmed Tinubu.
