Driver dies after truck plunges off bridge on motorway

A truck driver has died after his semi trailer plunged off a bridge on Brisbane’s Logan Motorway, with the wreckage lying undetected for up to 10 hours.

The NSW driver is believed to have crashed off the busy stretch of motorway about 11.30pm on Tuesday yet the truck wasn’t discovered until 9.30am the following morning.

Knowledge of the accident only came to light when a walker passed the wreckage on a morning stroll.

The truck had been travelling west along the Logan Motorway when the driver lost control, crashing off the bridge and down into the embankment below.

“It would be highly unlikely a motorists travelling at 100km an hour would have seen the truck,” Acting Senior Sergeant Ben Reeve said.

The impact was so severe, the truck’s trailer and its load of groceries was torn apart.

Frantic attempts by emergency services on Wednesday tried to free the driver, yet they were too late.

“We are liasing with TMR and Logan motorway to download footage of the highway,” Act. Snr Sgt Reeve said.

It’s not clear what caused the driver to lose control, but the forensic crash unit is investigating whether fatigue may have played a role.”

Following the discovery, traffic was backed up for kilometres as forensic officers examined the scene.

Congestion began clearing in time for the afternoon peak as the mammoth task of clearing the wreckage began.

Police are appealing for anyone who may have dashcam travelling along the highway last night to come forward.
