Another truck has wedged itself under a bridge at Ernest Street, South Brisbane.

Police were called to the scene at 10.15 this morning, where the truck driver has been trying unsuccessfully to unwedge the vehicle.

A fire crew was called to the scene about 11.30am, where they were working to deflate the tires down to try to dislodge it, however the emergency services may need to cut the roof off the truck to get it moving.

Ernest Street has been closed to traffic in both directions between Grey and Colchester streets while the truck was unstuck.
