AN UPGRADE to widen the driveway exit from Beaudesert State High School is expected to be complete before students return to school.
The promised car park extension, however, will not be finished for some weeks.
Scenic Rim MP Jon Krause said he had been lobbying for action on the issue since 2015.
He said he was pleased work was underway but found the overall delay "mind-boggling".
"My lobbying, and that of the community, has paid off and finally seen the government get on with the job," Mr Krause said.
"Anybody who has seen the traffic congestion around the high school in the afternoon pick-up times knows that work was needed to improve the carpark.
"This was always aimed at improving the flow of traffic out of the school, especially through a wider driveway allowing a left and right turning car at the same time.
"That better be the case when these works are complete.
"Given that school holidays are 6 weeks - in fact, longer this year - it's just mind-boggling that the government couldn't get it all done in that time.
"That said, the works were delayed two or three times during 2021 and so I'm pleased to see it happening."
Transport and Main Roads said the car park upgrade would continue for six weeks after school starts.
"Work to widen the driveway exit within the existing car park at Beaudesert State High School is expected to be complete before students return to school," a TMR spokesperson said.
"Additional spaces are due to be completed by mid-March."
The job had been scheduled to take place during last year's July school holidays to improve drop-off/pick-up times and safety.
Transport and Main Roads Minister Mark Bailey said at the time the $486,000 School Transport Infrastructure Program project would make it easier for drivers to access the school from the Mount Lindesay Highway.
"This is a win for parents, students and staff driving to and from school," Mr Bailey said.
"Widening the car park exit to two lanes with dedicated left and right-turns will cut wait times for drivers leaving, particularly in the afternoon once the school bell rings.
"New pedestrian fences will be installed around the car park to improve safety for people on foot, and new permanent car parks will be created as part of the project."
