Lanes, concrete pavement
Nigeria's largest road programme, and the first stretch of it runs through Lagos.
The Lagos–Calabar Coastal Highway runs roughly 700 kilometres across nine coastal states as a concrete dual carriageway, five lanes in each direction, elevated to withstand a fifty-year flood cycle. Section 1 covers 47.47 kilometres in Lagos, running east from Ahmadu Bello Way on Victoria Island.
We act for the Federal Ministry of Works on the Lagos section — the hydrological and hydraulic case for the corridor, the service lane design, and the technical work that comes with building a highway through settled communities.
Our role
Hydrological and hydraulic assessment
Pre-construction hydrological study and hydraulic design, mapping every outfall to the lagoon — existing and yet to be constructed — before the first embankment was raised.
Flooding technical evaluation
Establishing on engineering evidence the causes of flooding in adjoining communities, and the corridor's effect on the receiving drainage network.
Service lane design
Service roads on both flanks carrying secondary collector drains, re-routing stormwater from tenements to the nearest completed outfall.
Register of affected structures
Field survey of 147 structures along the service lane corridor — 97 on the northern flank, 50 on the southern — from Oniru to Okun Ajah.
Stakeholder briefing
Preparing the Ministry's technical position for affected communities, on the evidence rather than on perception.
