Traffic was backed up on the Ambassador Bridge Tuesday afternoon after a reported collision between three transport trucks.

Windsor police say bridge traffic was slow coming into Canada and has stopped heading to the U.S.

A truck driver stuck on the bridge around 1:30 p.m. told CTV News both directions were at a standstill. He says Windsor emergency crews attended the scene. The crash appeared to be right in the middle of the bridge.

Traffic was also lined up along Huron Church road leading to the bridge.

Police say there were no injuries.

All lanes were open again around 3:30 p.m.
