A 26-year-old West Wollongong man is in a critical condition in St George Hospital after his motorcycle collided with a 4WD on Mount Keira Road.
Emergency services had to free the rider who was trapped under the vehicle before he was airlifted to hospital.
The incident happened at the northern end of Mount Keira Road between Picton Road and Clive Bissell Drive just before 5pm yesterday.
Wollongong Police District officers established a crime scene and commenced investigations which forced the closure of the road for almost four hours.
Mount Keira Road reopened around 9pm last night.
The driver of the 4WD, a 18-year-old man, was uninjured.
He was taken to Wollongong Hospital for mandatory testing.
