AFTER spending 12 hours cleaning up a truckload of the explosive chemical ammonium nitrate that spilled across the Carnarvon Highway on Thursday afternoon, the road will again be closed so the overturned trailer can be removed.

Both directions of the highway were closed from late Thursday afternoon until 8.05am today, after a truck trailer overturned near the mining centre of Rolleston.

Queensland Fire and Emergency Services handled most of the clean up, while Queensland Police Service are now investigating the crash.

According to a police spokesman, the road would have to be closed again so the trailer can be removed.

He was unable to say when that would occur, or how long it would take.

Queensland police have released images of the area surrounding a truck explosion in Charleville overnight on the Mitchell Highway.

A truck driver was critically injured and two firefighters hurt when a B-double truck carrying the same explosive material crashed near Charleville in rural western Queensland.

When the ammonium nitrate exploded, it destroyed huge chunks of the road, fire engines and raised concerns over the laws that govern chemical transport.


Explosive chemical spills across Central Queensland highway

A TRUCK trailer carrying ammonium nitrate has rolled on Central Queensland's Carnarvon Highway, spilling the chemical across the road.

As of 9pm Thursday, the highway remained closed as emergency services cordoned off the area then worked to clean up the potentially explosive material.

In September, a B-double truck carrying 52 tonnes of the chemical crashed and exploded near Charleville injuring two fire fighters and leaving the truck's driver in a critical condition.
