The Lagos State Government has announced an 18-week maintenance programme for Mazamaza Bridge along the Lagos–Badagry Expressway.
The announcement comes amid plans to eventually demolish and reconstruct the bridge as part of Phase 2 of the Blue Line Rail project, a 14-kilometre extension from Mile 2 to Okokomaiko.
In a statement issued on Friday, the Commissioner for Transportation, Oluwaseun Osiyemi, said repair works would commence on Monday, 19 January 2026.
He explained that the maintenance would affect both the Toll and Service Lanes in both directions, with work focused on expansion joints and other critical bridge components. The bridge will remain partially open throughout the period, with traffic managed through planned diversions across the Toll Lane, BRT Lane and Service Lane.
According to the statement, the phased maintenance will run from 19 January to 28 May 2026. A preliminary phase from 24 to 30 January will prepare work zones and assess traffic control requirements.
Subsequent phases will address repairs on the Badagry-bound lanes between 31 January and 30 March, followed by works on the Lagos-bound lanes from 31 March to 2 June.
The government advised motorists to expect lane restrictions and plan their journeys accordingly, noting that the entire bridge will undergo repairs in both directions during the period.
Under the traffic management plan, Badagry-bound vehicles will alternate between the BRT Corridor and Toll Lane depending on the section under repair, while Service Lane works will temporarily reduce traffic to a single lane.
Lagos-bound traffic will follow similar diversions, with vehicles redirected between the Toll Lane and BRT Corridor as work progresses, before normal flow resumes beyond each repair zone.
Motorists were urged to obey traffic signs and follow instructions from officials of the Lagos State Traffic Management Authority to ensure safety and smooth movement.
The decision to rebuild the bridge follows structural tests conducted by the Lagos Metropolitan Area Transport Authority, which revealed that the existing structure cannot support rail operations. Officials said the planned replacement bridge will meet international standards and is expected to last at least 75 years.
