A 64-YEAR-OLD woman from Nowra was airlifted to St George Hospital in Sydney following a head-on collision on Bolong Road, north east of Nowra on Thursday afternoon.
Police said the accident happened about three kilometres south of the Shoalhaven Heads turn-off just after 5pm.
Police allege the Nowra woman, who was travelling south in a Toyota Town Ace van, veered onto the wrong side of the road behind a number of stopped cars who were waiting for another vehicle to turn into a nearby property and collided head on with a Toyota Hilux, which was travelling north, driven by a 21-year-old woman from Sydney.
The vehicles came to rest on the eastern verge of the roadway.
Emergency rescue crews took close to half an hour to release the woman from the van, who suffered severe head injuries.
She was transported by road ambulance to Zealand Oval at Shoalhaven Heads where the Ambulance Rescue Helicopter from Albion Park airlifted the woman to St George Hospital in a serious condition with head and possible spinal injuries.
Traffic was backed up for more than half an hour on Bolong Road, with contraflow put in place around the accident scene.
The driver of the Hilux was uninjured.
