Lekki–Epe Expressway Reconstruction
Upgrading the expressway from flexible to rigid pavement for long-life performance on the corridor carrying the Lekki industrial axis.
CLIENT
Lagos State Government
LOCATION
Lekki–Epe corridor, Lagos
SCOPE
Flexible to rigid pavement reconstruction
STATUS
Delivered
Flexible pavement was the wrong answer for what this corridor became.
The Lekki–Epe Expressway now carries the freight of an industrial axis that did not exist when the road was built. Flexible pavement under that loading, in this water table, fails faster than it can be maintained.
Reconstruction in rigid pavement trades a higher construction cost for a design life that matches what the corridor is actually being asked to do.
Our role
Pavement investigation
Condition survey, coring and subgrade assessment establishing the failure mechanism.
Rigid pavement design
Concrete pavement design for sustained heavy axle loading and a high water table.
Staging and traffic management
Phasing that kept the corridor in service through reconstruction.
Construction supervision
Site supervision, concrete quality control and certification.
