A truck loaded with beer has overturned on a motorway in Sydney’s west, with motorists warned to avoid the area.

Emergency workers were called to the M7 at Cecil Hills about 2.30am on Monday after the semi-trailer crashed and rolled.

Police said the driver suffered a head injury and was taken to hospital for treatment and mandatory tests.

The M7 is closed northbound and the speed limit for southbound motorists has been reduced to 40km/h.

“Emergency services and motorway crews are working to clear the scene; however, due to the nature of the crash, the motorway is expected to be closed northbound for some time,” police said in a statement on Monday.


The Transport Management Centre says drivers should expect delays, and those travelling north are being advised to avoid the area altogether.
