The Department of Main Roads is carrying out safety works on Tamborine-Oxenford Road between Jourdana Drive and Elevation Drive, Wongawallan.
The safety works are designed to slow down heavy vehicles at the Jourdana Drive descent point, by forcing them to use low gear and reduce speed before negotiating the steep descent.
At the conclusion of the project, speed for heavy vehicles and buses will be reduced permanently to 40km/h. General traffic will remain at 60km/h.
Temporary traffic changes will be in place while work is undertaken between mid-November and Mid-December. Work will be carried out intermittently between 6am and 6pm Monday to Friday and between 6pm and 5am Sunday to Thursday.
Temporary lane closures, reduced speed limits, signage and traffic control measures may be in place.
