Pedestrian Bridge In Ikire, Osun State Collapses (See Photo)

The sender said he was on his way to Kogi State and this happened. It happened tonight according to him.
How can a trailer bring down the bridge. What i saw there is something that looks like a bridge cos the trailer is not the same height as the bridge.
Poor construction, poor building material poor everything. Thank God there was no casualty. That bridge must have been 'weak for days'!
