New bridge length
50–100
Years design life
A city cannot take its central crossing out of service. It has to replace it anyway.
Carter Bridge is one of the three crossings between Lagos Island and the mainland. Structural fatigue on a link carrying that volume is not a maintenance question — it is a question of how you replace an asset while the city keeps using it.
The existing bridge runs 1.525 km as three lanes dualised. The replacement is designed as a modern high-capacity structure meeting international safety and engineering standards, with a flyover ramp and dual 105-metre navigational waterways beneath.
Our role
Structural assessment
Condition and fatigue assessment establishing the case for replacement over further strengthening.
Reconstruction design
Full engineering redesign of the crossing to a 50–100 year design life.
Decommissioning and demolition
Sequencing the removal of the existing structure against the city's tolerance for lost capacity.
Navigational clearance
Dual 105-metre navigational waterways and the flyover ramp arrangement.
Construction supervision
Supervision of works delivered by CCECC.
