Huge delays on Sydney’s M4 after car, truck crash at Minchinbury

Sydney commuters are facing delays on a major motorway after a four-vehicle smash, with traffic stretching for up to 10km.

A four-vehicle crash has caused major delays on Sydney’s M4, one of the main citybound routes from the city’s western suburbs.

Three cars and a truck collided on the M4 eastbound at Minchinbury - between Wallgrove Rd and the M7 offramp - at about 5.50am on Thursday, police say.

Two of the three eastbound lanes were closed approaching the M7.

Live Traffic NSW’s map showed significant traffic jams stretching as far as 10km.

Traffic cameras near the scene show significant congestion as commuters begin their morning journey towards the city.

Paramedics treated one of the car drivers – a 65-year-old woman – at the scene, before she was taken to Westmead Hospital in a stable condition.

The other drivers - a 25-year-old man, a 38-year-old man, and the 42-year-old truck driver - were all uninjured in the collision.

The incident is under investigation by officers from the Traffic and Highway Patrol Command.

Anyone with information or footage of the crash has been urged to come forward and contact Crime Stoppers.

All citybound lanes of the M4 have since been reopened, and traffic appears to have begun easing as of 8am. Significant delays are still expected.

More to come.
