THE Burnett Hwy just north of Tansey was impassable yesterday and would be for some time, Goomeri Police Sergeant Warren Lohman said.
Sgt Lohman said flooding had caused major damage to the highway about half a kilometre north of Tansey, and left a large amount of debris on the highway about 17km south of Goomeri at Barambah Bridge.
"When the bridge is open, it will be one-way only," he said.
Sgt Lohman said more than 400mm of rain had fallen in Goomeri during the extreme weather event, flooding the main road through the town.
While no houses were inundated, several businesses had been flooded, he said.
"The water went higher in the main street than the last time (2011).
"The new truck stop on the southern outskirts suffered a fair bit of damage because Nangur Creek broke its banks and the BP service station was flooded and has water damage.
"The Goomeri swimming pool fence was knocked down by flood-waters and the pool is now full of mud.
"The information centre had flood water through it and part of Maudsley St was washed away, exposing town water supply pipes and sewerage.
"Some of the pipes were washed away but water has been restored to most of the town."
Sgt Lohman said the school oval was covered in debris.
"I think most of Maudsley St is on the oval and fencing has been knocked down at the school which is closed today (Tuesday) but will open tomorrow (Wednesday)," he said.
