Police have a lead as to which vehicle is allegedly responsible for damaging a pedestrian bridge last month. 

On July 21, a vehicle struck the pedestrian bridge on Highway 15 just before the turnoff to 95 Street. 

Blocks of concrete fell onto the road below, which forced RCMP to reduce the road to one lane. 

New surveillance footage shows a red semi tractor-trailer hauling a large boom on its flat deck trailer.

RCMP are looking to speak with the driver.

If you have any information regarding this semi truck or its driver, you can contact the Fort Saskatchewan RCMP at 780-997-7900. If you want to remain anonymous, you can contact Crime Stoppers at 1-800-222-8477.
