The Federal Ministry of Works has deployed advanced engineering solutions, including geotextiles and rock layering, to tackle an ocean threat on the Lagos-Calabar Coastal Highway under construction.
Minister of Works, Sen. Dave Umahi, gave the assurance on Monday, August 18, 2025, during a tour of some roads and bridge projects in Lagos State.
Umahi said that the ocean nearly broke into the carriageway at kilometre 14.6, posing a threat to the highway project.
He said that the ministry deployed advanced engineering solutions for reinforcement on the section.
“This additional work was not anticipated and has eaten into the project’s contingency fund,” he said.
The minister said that failure to address the matter could negatively affect the entire project.
He commended the project contractor and supervisors for a swift response that saved the highway from ocean encroachment.
Umahi has dismissed social media reports alleging lack of drainage systems on the Lagos-Calabar Coastal Highway under construction.
Umahi said that the coastal highway project included 750km dual underground drainage systems.
“People say there is no drainage system. I don’t know why people take much delight in false information. It is very damaging.
“We have 750km of underground drainage system by two, which is 1500km. You can see the pipes,” Umahi said.
He praised the contractor handling the project, Hitech Construction Ltd., and the project supervisors for ensuring safety and durability of the coastal highway.
The Lagos-Calabar Coastal Highway is 750km long.
The highway is a major infrastructure project designed to connect Lagos to Calabar, passing through nine coastal states.
The highway construction began in March 2024 with the first phase of the project which covers 47.47km within Lagos.
The project will feature a six-lane highway, concrete construction with a flood-resistant design, and solar-powered streetlights.
It will also feature a train system, modern toll gates and closed circuit television surveillance, among others.
The project aims to improve connectivity, reduce travel time and boost economic activities.
Umahi said his presentation to the Federal Executive Council about Lagos bridges was distorted on social media.
He said in Lagos that the misrepresentation led to speculations and even mockery by ill-informed members of the public.
Umahi urged the public to rely on verified government updates instead of social media misinformation.
He said that both Third Mainland and Carter bridges had been under technical review since 2013.
He emphasised that saltwater penetration, illegal sand mining and rusting of piles had worsened their structural defects.
The minister said that technical inspections of Lagos bridges in 2013, 2019 and 2023 showed deterioration under water.
”Specialist contractors and consultants reported that Carter Bridge’s defects were advancing exponentially.
”Findings revealed heavy corrosion, pile weakening and sand erosion due to neglect and illegal dredging,” he said.
According to Umahi, bridge construction experts have advised that Carter Bridge should be demolished and replaced.
He said that stakeholders and contractors agreed that replacement was safer and more cost-effective than repairs.
“If we repair Carter Bridge for another 50 years, it is going to take N389 billion but to construct a brand-new bridge that will also increase the span for navigation will cost about N359 billion.
“That is what they said to us. That is Berger’s own estimates. We didn’t call for bidding, we called for information,” he said.
He said that he had not given the Federal Executive Council any figure for approval.
“We have not presented any figure for approval, we have given them the idea of what Berger sent, and we say we don’t trust that figure.
“If they are more than six or seven people that quoted, we can begin to trust.”
Umahi, however, said that experts did not recommend demolition of the Third Mainland Bridge.
He noted that the surface repairs on the Third Mainland Bridge had been completed.
He gave the assurance that monitoring and maintenance would continue on the bridge to avoid further deterioration.
”Specialist contractors and independent diving consultants confirmed stability for now,” he said.
The Minister reiterated Federal Government’s commitment to ensuring public safety on all federal bridges.
