Dave Umahi minister of works
April 4, 2025
The Federal Government on Friday re-opened the Independence Bridge in Lagos, following emergency repair works it carried out overnight.
At the re-opening, the Minister of Works, Sen. Dave Umahi, assured the public of the bridge’s safety and reiterated plans for permanent repairs.
The minister explained that the closure of the bridge was prompted by structural failure of its approach slab, which caved in due to a faulty design.
He said that the initial construction of the approach slab was done as a cantilever, which was structurally inappropriate.
“It is not supposed to be a cantilever. What we had was a free-standing approach slab, which is incorrect.
“Every approach slab must have at least one end fixed,” he said.
He said that the slab failed when the sandfill beneath it leaked, compromising its integrity and posing a serious risk.
Umahi, who described the situation as an emergency, admitted that proper procedures were not followed in announcing the closure of the bridge.
He announced plans to introduce a standardised national procedure for road and bridge closure.
He said: “Going forward, no road or bridge in Nigeria will be closed without a clearly-defined process.
“Controllers must submit drone surveys, state the nature of the technical problem and solution, propose alternative routes, and publish this information to the public.”
He said that the Independence Bridge was set for re-design to ensure long-term stability.
“We have decided to re-design the project as a one-span bridge. This will eliminate the lateral head pressure on the abutment and address factors such as piling depth,” he said.
Umahi said that bridges in Lagos State, including Third Mainland, Carter and Iddo, were held by skin-friction piling, adding that they depended on the surrounding sand for stability.
According to him, any scouring or sand excavation puts the piles at risk.
He said that ongoing studies would guide further reinforcement work.
The minister added that more permanent works would commence on the Independence Bridge in three weeks time after verification of the integrity of underground piles.
Umahi emphasied that future construction schedules would be designed for the convenience of the public, with some projects carried out exclusively on weekends or at night.
He also said that the Lagos State Traffic Management Authority would be involved in traffic monitoring during the repairs.
“This is not just about engineering; it is also about communication, safety, and accountability.
“We owe it to Nigerians to do better,” Umahi said. (NAN)
