COMMUTER CHAOS: 15km snarl after four highway lanes closed

A TRUCK rollover closed four lanes of the M1 this afternoon, causing a peak hour standstill.

Four northbound lanes were closed at Slacks Creek, near Logan, causing more than 15km of backed-up traffic to Eagleby just after 4pm.

Paramedics were on the scene treating one person however it is not believed the injuries were serious.

Diversions were in place via exit 24 but congestion had cleared by 6.35pm.

A crash near Springwood was also causing congestion for southbound traffic on the M1 this afternoon.

Delays were back to Upper Mount Gravatt on the M1 at 4.50pm and back to Murarrie on the Gateway Mwy. The Gateway congestion had cleared by 6pm and M1 congestion was clear by 6.35pm.

It followed a crash that left a motorbike rider in a critical condition after he crashed while riding without a helmet on the Gold Coast.

Police said early information indicated the man was riding a dirt-bike on Gordon Drive, Coomera when he lost control and crashed into a light pole at about 12.30pm.

The 47-year-old was not wearing a helmet at the time and sustained life-threatening head injuries.

He was taken to Gold Coast University Hospital in a critical condition where he remains.

He was believed to have been wearing thongs for footwear.

Lachy McPherson was the first person on the scene of the crash in the quiet culdesac.

He was working on a nearby job site when he heard a motorbike "tearing down the street" before clipping the kerb and smashing into a light post.

"We just heard this loud screech and a big crash," he said

"He's come down the street, run too wide and went straight into the pole, his bikes skipped up a bit further.

"Not sure if he had a helmet on or nothing.

"We went straight down and rang the ambos.

"He was spitting blood and his arm and shoulder had snapped, he was in all sorts.

"He was just grabbing at his hurt bits but he was pretty unresponsive, he was rooted.

"We just stayed with him until the ambos came but he wasn't in a very good way."

The injured man's thongs and a ripped black T-shirt where strewn around the light post, one thong flung several metres away.

Police on the scene said they could not comment on what happened until they had completed an investigation.

The driver was transported to Gold Coast University Hospital in a critical condition.

Meanwhile a woman has come off her scooter at Arundel on Brisbane Road.

She came off the scooter around 1.15pm and sustained minor injuries.
