Two men have been taken to hospital after three cars and a truck collided on the M1 at Cooranbong just before 7am this morning.
One of the drivers – aged in his 60s – was flown to John Hunter Hospital in a serious condition, with head and chest injuries.
While a man in his 50s was transported by road with minor injuries.
The collision caused significant traffic delays, with cars banked up more than 8 kilometres, as northbound lanes closed.
Lanes have since been reopened.
