A cement truck slammed into a rail bridge Friday morning just west of London, Ont.
The crash happened on Amiens Road, near Komoka.
The bridge has a metal structure designed to help drivers gauge the clearance and prevent impacts with the bridge.
In this case, the impact was so heavy that it twisted the metal, pulling two large boulders away from the wall of the bridge.
The boulders sat suspended in air with the metal resting on the truck.
Amiens Road was closed from Glendon to Oriole Drive while crews strategized how to lower the boulders and free the truck.
There were no reported injuries.
