Floodwaters covered a section of the Benin-Ore Expressway Thursday and left travelers stranded.
Motorists and passengers stepped out of vehicles to watch the water flow across the road.
Footage from the scene shows people wading through the flooded stretch while others stand nearby and react.
The expressway serves as a key route between Benin City and Ore.
Travelers now search for detours as crews assess the situation.
Meanwhile, the event comes months after a suspected attack on a bus in the same area.
Officials have not yet released details on when crews will clear the water or reopen the road.
Drivers in the region plan their trips with care until conditions improve.
