UPDATE: Truck that caught fire drove through area with mulch
5.40PM - UPDATE: CHILDERS police have confirmed that a truck transporting a load of sugar cane mulch caught fire earlier today and have labelled the driver 'a silly man doing a silly thing'.
The police spokesman said the south-bound lane had recently been re-opened after the blaze shut down the highway.
"A guy who was transporting the mulch up north decided to follow other trucks through the fire and the fire ignited the cane mulch," the spokesman said.
"The driver was able to unhook the trailer and get the cab to safety, but it's taken hours for firefighters to extinguish the mulch and trailer.
"The north-bound lane is still closed but I would imagine it should be open within the next half hour."
The officer said firefighters had used hoses to clean off the south-bound lane but it was possible the engulfed trailer could have melted the bitumen, and assessing the damage could take longer.
"Cane mulch is the perfect fuel for a fire, it was a silly thing to do," the police spokesman said.
"I have seen the heavy recovery vehicles come and go so I assume the trailer has been removed from the site now."
He said the grass fire was still burning and making its way toward Childers, but not at any excessive rate to cause immediate worry to residents.
3.17PM - UPDATE: SEVEN crews are currently on scene working to contain a grass fire that was sparked when a B-double truck transporting bails of hay caught fire.
When crews arrived the prime mover has been disconnected from the trailer and no persons were trapped.
A QFES spokesman confirmed that as of 3.02pm the Bruce Highway was closed to traffic and a recovery vehicle was on site.
"The heavy recovery vehicle will remove the trailer when it is safe to do so," he said.
"An excavator is on site breaking up the hay and there is currently no danger of the fire spreading to nearby bushland.
"Crews are still on scene and are likely dampening hot spots."
1.33PM - BREAKING: A TRUCK understood to be carrying a load of hay has caught fire south of Gin Gin.
Emergency services are believe to be responding via Booyal Dallarnil Rd.
The exact location of the incident is yet to be confirmed.
Initial reports suggest the fire has also caught ablaze along the roadside where the truck was parked.
