THE HEAD Rd at Teviot Falls will remain closed until March with Scenic Rim Regional Council and contractors working hard to reopen the popular tourist route.

The road sustained significant damage after land slips and undermining during ex-tropical cyclone Oswald early last year.

Scenic Rim Regional Council Mayor John Brent said, because of the steep terrain of the route, there were significant challenges to repair.

"There's near vertical drop-off cuttings and a narrow road corridor," he said.

"Detailed investigations and design planning were required to ensure the construction of an appropriate engineering and safety solution." As a result of the damage, the Queensland Reconstruction Authority approved restoration measures including new retaining walls along affected sections.

"Some of these sections are worth almost $350,000 which will reduce the risk of future land slips and road closures," Cr Brent said.

Cr Brent said council appreciated the inconvenience this road closure had caused residents.

"We'd like to thank residents, business operators and the travelling public for their patience and understanding while we continue to work on the road," he said.

"Locals have been kept up-to-date on the process through regular communication from council."

Until the road is repaired drivers wanting to travel from Killarney through to Boonah can use the detour which includes White Swamp Rd and Carneys Creek Rd. The detour is gravel in some sections.
