The tanker was travelling from Abeokuta to Lagos when the incident happened.
The tanker was said to have fallen due to the bad condition of the road.
Motorists travelling inward and outward Abeokuta were forced to divert to other inner routes inside Ilogbo, Onihale, and Ijoko among others.
Gridlock had also built on these adjoining roads, which are also in bad shape.
Meanwhile, fire fighters, and operatives of the Federal Road Safety Corps, the police and the Ogun State Traffic Compliance and Enforcement Corp are currently on the ground.
