Work is nearing an end at the Merivale Street crossing on the western side of Allora.
After being washed out by flooding the crossing will have a larger, more solid culvert.
A spokesperson for the Southern Downs Regional Council said the culvert is well advanced with final concrete works almost completed.
In the next two weeks erosion protection works, road sealing and signs should be finished.
The increased size of culvert will provide increased flood immunity whilst concrete batter and erosion works will provide a more resilient structure for future flood events.
The culvert capacity has been increased from 1/375mm diameter concrete pipe to 3/1200x900mm concrete box culverts.
Weather permitting, works are expected to be completed and the road open by 22 December 2023.
