Emergency services are currently at the scene of the crash, which is expected to cause hours in delays along the highway.

A Queensland Police Service (QPS) spokeswoman said it was likely weather played a role in the crash, which happened about 8.15am today (February 25).

She said no one was seriously injured in the crash.

The incident has caused major disruption from Dinmore after the truck smashed through a guard rail before the before the Kholo Rd exit at Blacksoil.

Police have diversions in place via the Cunningham Hwy but drivers have been warned to expect long delays.

As of 12pm the Hwy remained shut and police continued to divert traffic while waiting for heavy haulage units to arrive and remove the truck.

The spokeswoman said motorists were urged to avoid the area.

Despite initial QPS reports the road would be closed for three hours, the spokeswoman said there was no estimated time for when the road would be open.

A Queensland Ambulance spokeswoman said one crew was called to the scene but they were not needed.

It comes as a deluge causes further mayhem on southeast Queensland roads today.

QPS issued an additional warning to drivers along the Warrego Highway, saying other parts had been affected by flooding.

“Parts of the Warrego Highway north of Gatton will also be closed due to ongoing flooding — motorists are advised to avoid roads in the area,” read a Twitter post.

“The Toowoomba Connection Road at Withcott is [also] closed in both directions due to localised flooding, closing the Toowoomba Range in both directions.”
