Julius Berger Nigeria Plc on Monday provided updates on the rehabilitation of major bridges in Lagos State, saying the projects are aimed at addressing years of structural deterioration affecting key transport infrastructure.
The company said construction began in January 2024 on the Third Mainland Bridge, Carter Bridge, Iddo Bridge and the Iddo Bridge Underpass following its engagement by the Federal Ministry of Works in 2023.
According to Julius Berger, the rehabilitation programme focuses on repairing long-standing structural damage caused by marine corrosion, tidal forces and heavy traffic.
The company said work on Carter Bridge concentrated on deteriorated underwater sections and substructure components affected by corrosion and tidal movement.
Physical construction on the bridge was completed in January, while the project has entered its close-out phase.
For the Third Mainland Bridge, engineers are carrying out repairs on critical structural components, including the deck soffit, piers and underwater pile caps.
Julius Berger said the project is about 80 per cent physically completed, with only the monitoring phase remaining.
The monitoring phase, expected to last one year, is currently in its third month. The company added that about 60 per cent of the project budget has been allocated, while 21 per cent of the total project value has been executed.
It said no major construction work remained on the bridge, with attention now focused on performance validation.
The rehabilitation of Iddo Bridge involves extensive reconstruction due to severe structural deterioration.
According to the company, significant portions of the bridge have been demolished and are being rebuilt with reinforced concrete girders, improved reinforcement systems and strengthened supports.
The project has reached 30 per cent physical completion.
At the Iddo Bridge Underpass, the existing structure was completely removed for full reconstruction.
The scope of work includes continuous reinforced concrete pavement, upgraded drainage systems and the installation of modern street lighting and utility infrastructure.
Construction progress at the underpass has reached 38 per cent.
Julius Berger explained that continuous reinforced concrete pavement systems are designed to control cracks rather than eliminate them, with reinforcement preventing cracks from widening.
The company said the rehabilitation projects are expected to improve commuter safety, extend the lifespan of critical infrastructure and reduce structural risks along some of Lagos State’s busiest transport corridors.
It added that the projects would also improve traffic flow and support economic activities across the state.
