Thirsty Sydneysiders may have to wait a little longer to blow the froth off a few, after a truck laden with cartons of beer became wedged under a motorway overpass.

Cartons of beer were unloaded from the B-double, which became stuck under an M4 overpass on Arthur Street in Granville about 10:00am.

Police are assessing damage at the site. There are no reports of injuries.

Traffic is continuing to use the M4 overpass but traffic has been stopped on Arthur Street.

Vision shows that the truck appears to have made it under two nearby overpass bridges, but hit trouble under the third.

Police say they have spoken to the driver and it is likely to be a few hours before the truck is removed.
