A truck towing a digger became stuck under the Commonwealth Bridge overpass on Parkes Way causing traffic delays on Tuesday afternoon.
The incident occurred about 4pm.
One westbound lane of Parkes Way was closed as the scene was being cleared but has since reopened.
An ACT Policing spokesman said the truck was too tall for the bridge and got stuck underneath, causing debris to fall onto the road.
The truck was removed from the scene but a lane remained closed. The lane has since reopened.
An ACT Roads engineer attended to the scene, but Fire and Rescue and an ambulance were not needed.
