The Department of State Growth has commenced rock face maintenance work on the Huon Highway between Sandfly and Lower Longley started on Monday, 30 August.
The routine maintenance works include installing rockfall mesh and rock catching fencing along the exposed rockface.
It is expected these works will be completed by late October 2021.
For safety of workers and road users during works, the two southbound traffic lanes (heading towards Huonville) near the worksite will be closed at all times until works are complete.
Southbound traffic will be temporarily diverted onto one of the northbound lanes, and there will be one lane available for travel in each direction.
A section of the concrete barrier will be removed just before the worksite to allow traffic to move onto the new traffic arrangement.
There will be a reduced speed limit of 60km/h during our working hours, 7am to 5pm, Monday to Friday.
Outside of these working hours the speed limit will be 80km/h.
Traffic management will be in place to guide traffic and road users should allow extra travel time if travelling through this area.
Road users are reminded to keep to the posted speed limits and follow the directions of traffic controllers and signs.
