WEST Tamar Highway upgrades are on track to be completed by late February to early March.
The Department of Infrastructure, Energy and Resources this week confirmed the upgrade near Brady's Lookout was being completed in the projected timeframe.
The roadworks, which includes installing a flexible safety barrier separating the north and south-bound lanes, aims to improve safety by preventing head-on crashes and reducing the severity of loss of control crashes.
Tasmanian company Andrew Walter Constructions are completing the works.
``The use of flexible safety barrier has the ability to achieve up to a 90% reduction in serious road trauma caused by head-on and run-off-road crashes,'' she said.
``This section of the West Tamar Highway carries about 5500 vehicles a day, including commuters, tourist traffic on the Wine Route and heavy vehicles, and has a significantly higher crash rate than other sections of the highway.''
The $9 million upgrade brings the state government's investment in the West Tamar highway to about $29 million.
