At about 3am a tyre blew on the truck that was heading south near the Houston Mitchell turn off.

The driver pulled off to the side of the road and noticed a fire had started on a tri-axle trailer.

The man worked quickly detaching one trailer and the fire took hold of another.

Police and fire rescue arrived at the scene and blocked off a southbound lane.

Traffic restrictions in the area will remain until the damaged vehicle can be towed.
