Carter Bridge faces 24-month repair window on critical structural failure

The Federal Government has blamed the structural failure of Lagos’ 1.58-kilometre Carter Bridge on detached piles, significant corrosion, years of inadequate maintenance and illegal sand mining, exposing the vulnerabilities of one of the city’s key transport links.

Dave Umahi, Minister of Works, disclosed this on Monday during an inspection of the ongoing reconstruction of the Carter and Iddo Bridges in Lagos.

Umahi said the Carter Bridge, which has served Lagos for about 60 to 70 years, had suffered significant structural deterioration, prompting the Federal Government to commence its reconstruction.

The minister said the government was targeting completion within 24 months, instead of the initially proposed 36 months, given the bridge’s importance to movement across Lagos.

He also said the government would continue maintaining the bridge during the reconstruction to prevent a complete closure that could worsen traffic congestion in the city.

The findings raise concerns about the long-term condition of ageing infrastructure in Lagos, where bridges and roads carry heavy traffic and serve as critical links for commuters, businesses and logistics operators.

According to Umahi, the deterioration of Carter Bridge was driven by several factors, including detached piles and extensive corrosion of structural components. Years of inadequate maintenance and illegal sand mining around the bridge also contributed to its weakened condition.

The reconstruction is being carried out alongside work on the Iddo Bridge as the Federal Government seeks to restore the safety and reliability of the ageing infrastructure.

The decision to maintain access to the Carter Bridge during reconstruction is aimed at limiting disruption to traffic and economic activities. A complete shutdown could force thousands of commuters and commercial vehicles onto already congested alternative routes.

For Lagos, where traffic congestion remains a major drag on productivity, prolonged closure of a major bridge could increase travel times and raise transportation and logistics costs.

The government’s decision to cut the construction timeline from 36 to 24 months could therefore reduce the period of disruption if the revised deadline is achieved.

However, the condition of Carter Bridge also highlights the wider challenge of infrastructure maintenance in Nigeria. The deterioration of a bridge that has served the city for decades underscores the cost of delaying routine maintenance until major rehabilitation becomes unavoidable.

The success of the reconstruction will ultimately depend not only on meeting the revised completion deadline but also on establishing a stronger maintenance regime to protect the bridge from renewed deterioration.

It also places greater emphasis on enforcing regulations against activities such as illegal sand mining that can undermine major public infrastructure.
