The Lagos State Government has announced an 18-week maintenance programme for the Mazamaza Bridge along the Lagos–Badagry Expressway, ahead of its planned demolition and reconstruction as part of the Blue Line Rail Phase 2 extension from Mile 2 to Okokomaiko.
In a statement issued by the Commissioner for Transportation, Oluwaseun Osiyemi, the government said repair works will commence on Monday, January 19, 2026. The maintenance will affect both the Toll and Service Lanes in both directions, with work focused on expansion joints and key structural components of the bridge.
Osiyemi assured motorists that the bridge will not be completely closed during the exercise, noting that traffic will be managed through diversions across the Toll, BRT, and Service Lanes to minimise disruption. He said a detailed traffic diversion plan has been released for the maintenance works on both the inbound and outbound sections of the Lagos–Badagry carriageway, which will run from January 19 to May 28, 2026.
According to the schedule, a preliminary phase from January 24 to 30 will involve setting up work zones and assessing traffic conditions. Phases one to four, spanning January 31 to March 30, will focus on repairs on the Badagry-bound lanes, while phases five to eight, from March 31 to June 2, will cover the Lagos-bound lanes.
Motorists are expected to experience lane restrictions throughout the 18-week period. During repairs on the Badagry-bound lanes, the BRT corridor will temporarily serve as a diversion when work affects the Toll Lane, while the Toll Lane will be used when repairs move to the BRT corridor. Maintenance on the Service Lanes will reduce traffic flow to a single lane before normal access is restored. Similar diversion arrangements will apply during works on the Lagos-bound lanes.
Drivers have been advised to comply with traffic signs and follow instructions from officials of the Lagos State Traffic Management Authority to ensure safety and smooth traffic flow during the maintenance period.
The planned repairs come ahead of the bridge’s eventual reconstruction. In December 2024, the Director of Rail Transport at the Lagos Metropolitan Area Transport Authority, Olasunkanmi Okusaga, said structural assessments revealed that the existing bridge lacks the strength required to support rail operations. He explained that the new Mazamaza Bridge will be built to international standards, supported by 66 piers, and designed to last at least 75 years.
