Umahi Draws a Red Line Around the Niger Bridge
Works Minister orders crackdown on illegal sand excavation as erosion, vandalism and dredging raise fresh concerns over the safety of Nigeria’s critical bridge infrastructure
Exclusive to Ekocity | Infrastructure & Transport Desk
The Federal Government is tightening the perimeter around the First and Second Niger Bridges, with Works Minister David Umahi warning that illegal sand excavation and dredging will no longer be tolerated around the critical infrastructure.
During an inspection of the two bridges in August, Umahi ordered the immediate arrest of anyone found excavating sand around the Second Niger Bridge, where erosion had already emerged as a threat to the structure.
His warning is rooted in a broader concern: a bridge does not only depend on what motorists can see above the water. Its most vulnerable and expensive components may be beneath it. Illegal dredging can alter the riverbed, disturb the material supporting foundations and expose structures to forces for which they were not designed.
The Federal Government had already announced a 10-kilometre prohibition on mining and sand-mining activities around bridges nationwide, with Umahi saying patrol boats would be deployed to help enforce the restriction. The concern around the Niger bridges has also been compounded by vandalism.




At the First Niger Bridge, Umahi discovered that bolts, expansion joints and other critical metal components had been removed, prompting orders for immediate repairs as well as the installation of CCTV cameras and solar-powered lighting.
The government subsequently moved to strengthen surveillance, linking the proposed monitoring system to security agencies so that suspected vandals can be identified and apprehended.
For Umahi, the message is increasingly blunt: Nigeria cannot spend billions building strategic transport infrastructure only to allow criminal activity and uncontrolled extraction to undermine it.
The issue is larger than the Niger Bridge. Nigeria’s bridges carry highways, commerce and entire regional economies. Once a major crossing is compromised, the consequences can extend far beyond engineering — disrupting freight movement, commuting and local businesses.
The minister’s intervention therefore represents a shift from simply building infrastructure to protecting infrastructure.NThe challenge now is enforcement.
Warnings alone will not stop illegal dredging. Surveillance, patrols, prosecution and sustained monitoring will have to follow. For the Niger Bridge, the river may be underneath the road. But increasingly, the battle to protect the bridge is being fought beneath the water.
