The Lagos State Government has announced an 18-week maintenance programme for the Mazamaza Bridge on the Lagos–Badagry Expressway, as part of preparations to demolish and reconstruct the bridge for the Blue Line Rail Phase 2 extension from Mile 2 to Okokomaiko.
In a statement released by the Commissioner for Transportation, Oluwaseun Osiyemi, the maintenance work is scheduled to begin on Monday, 19 January 2026, and will run until Thursday, 28 May 2026. The repairs will cover both the Toll and Service Lanes in inbound and outbound directions, with particular attention on expansion joints and other critical structural components.
Osiyemi explained that the bridge will remain open throughout the maintenance period, noting that traffic will be managed through carefully planned diversions across the Toll, BRT, and Service Lanes to minimise disruption for motorists.
“The Lagos State Government has released a traffic diversion plan for the maintenance works on the expansion joints and bridge elements of Mazamaza Bridge along the Lagos–Badagry Carriageway, inbound and outbound, commencing from Monday, 19 January 2026 to Thursday, 28 May 2026,” the statement said.
According to the outlined schedule, preparatory works will take place between 24 and 30 January to set up work zones and assess traffic flow. Phases one to four, running from 31 January to 30 March, will focus on repairs along the Badagry-bound lanes. This will be followed by phases five to eight, from 31 March to 2 June, concentrating on the Lagos-bound lanes.
Motorists should expect lane restrictions throughout the duration of the maintenance exercise. During repairs on the Badagry-bound lanes, traffic will be diverted alternately between the BRT Corridor and the Toll Lane, depending on the section under repair. Work on the Service Lanes will temporarily reduce traffic to a single lane before normal flow is restored. A similar diversion pattern will be applied during repairs on the Lagos-bound lanes.
The government has advised road users to comply with traffic signs and follow directions from officials of the Lagos State Traffic Management Authority to ensure safety and smooth traffic movement during the maintenance period.
The planned maintenance comes ahead of the full reconstruction of the Mazamaza Bridge. In December 2024, the Director of Rail Transport at the Lagos Metropolitan Area Transport Authority, Olasunkanmi Okusaga, disclosed that structural assessments showed the existing bridge was not strong enough to support rail operations. He added that the new bridge would be built to international standards, supported by 66 piers, and designed to last for at least 75 years.
