Sydney's Parramatta Road Closed, Traffic In Chaos After Truck Accident

Peak hour traffic has been thrown into chaos after a female cyclist was hit by a truck on Sydney's Parramatta Road.

One lane of the major arterial road has been re-opened for westbound motorists following the crash at Glebe on Thursday evening that left the woman in a critical condition.

Parramatta Road runs from the city to the western parts of Sydney, and the crash -- just before the 5pm peak hour -- threw traffic into chaos.

Six ambulance crews and a helicopter were called to the scene at the intersection of Parramatta Road and Ross Street, a spokesperson for NSW Ambulance said.

Emergency services remained at the scene while the cyclist, aged in her 30s, was treated by paramedics.

She was taken to Royal Price Alfred Hospital in a critical condition.

Westbound motorists who need to use Parramatta Road are able to pass the site of the crash using one of the eastbound lanes under a contra flow.

But traffic remains very heavy around Camperdown and Newtown, with motorists being urged to avoid the area if possible and use Victoria Road and City West.
