Gateway gridlock after car crashes into concrete barrier

There are heavy delays on the Gateway Motorway after a car crashed into a concrete barrier and police closed one lane to clear the wreckage.

The crash happened on the southbound side after the Sandgate Road overpass in Taigum just after 8am with the driver, believed to be a man, suffering life-threatening injuries.

Australian Traffic Network reporter Ben Mihan said police had closed the left lane soon after the crash in order to clear the wreckage. However, the lane reopened just after 10am.

Mr Mihan said about five kilometres of southbound delays remained when the motorway reopened, with traffic stretching back to Bald Hills.

Police said reports from the scene indicated the driver may have suffered a medical incident behind the wheel and the Forensic Crash Unit was expected to travel to the scene.
