Julius Berger Nigeria PLC has intensified rehabilitation work on several key bridges in Lagos, addressing long-standing structural deterioration across major transport corridors in the state.
The project is being executed under a contract awarded by the Federal Ministry of Works in 2023, with physical construction commencing in January 2024. The intervention covers four major routes: the Third Mainland Bridge, Carter Bridge, Iddo Bridge, and the Iddo Bridge Underpass.
According to project details, the rehabilitation works are focused on restoring structural integrity, particularly in underwater components affected by marine corrosion, tidal forces, and years of heavy traffic.
At Carter Bridge, engineers completed key repairs on underwater and substructure elements aimed at mitigating corrosion and environmental damage. The physical works were completed in January, and the project is currently in its close-out phase.
The Third Mainland Bridge, one of Nigeria’s busiest transport corridors, has undergone extensive structural repairs, including work on deck soffits, piers, and underwater pile caps. The project has reached about 80 per cent completion, with only the monitoring phase remaining.
A member of the project team explained that the current stage is focused on performance validation rather than active construction.
“At press time last week, no major construction work is outstanding on this bridge as the focus is entirely on performance validation,” the official said.
“The monitoring phase acts as a quality assurance and risk management step, ensuring that the extensive rehabilitation work translates into a safe, stable, and durable bridge for years to come.”
The monitoring phase is expected to last one year and is currently in its third month. About 60 per cent of the project budget has been allocated, while 21 per cent of the total contract value has been executed so far.
Work on Iddo Bridge has proven more extensive due to severe structural damage. Large sections have been demolished and are being rebuilt using reinforced concrete girders and upgraded support systems. The bridge is currently at 30 per cent completion.
At the Iddo Bridge Underpass, the existing structure has been completely removed to allow for full reconstruction. The project includes continuous reinforced concrete pavement (CRCP), improved drainage systems, modern street lighting, and upgraded utility infrastructure. Construction progress stands at 38 per cent.
Engineers noted that CRCP technology helps control cracking by reinforcing the pavement so that any cracks that form remain stable and do not widen over time.
Overall, the rehabilitation programme is expected to enhance commuter safety, extend the lifespan of critical infrastructure, and reduce structural risks along some of Lagos’ busiest transport routes. It is also expected to ease congestion and support economic activity in the state.
