A section of the Bruce Highway in north Queensland has re-opened, after a giant hole emerged on the road on Wednesday.

Road crews spent the night repairing the two-metre wide hole in the road, and filled the damaged area with gravel on Thursday morning.

Queensland Police said they first received reports of a "sinkhole", on the highway between Bowen and Proserpine near the Whitsundays, about 7.15pm on Wednesday.

But on Thursday morning, a Transport and Main Roads spokeswoman said void in the ground was not a sinkhole, rather a large "pothole" caused by water seeping through the pavement.

"We have done excavation and repairs throughout the night and our priority is the safety of all road users and reopening the road as soon as possible," she said.
