Work to improve visibility for drivers on a 41-mile stretch of the A9 is to be carried out.
More than a 100,000 square metres of scrubland and vegetation is being cleared along the road from Perth to Dalnacardoch.
Transport Scotland said lane closures and speed restrictions will be in place while the £122,000 programme to improve the roadside environment is being carried out.
The work is expected to last until early March.
Chair of the A9 Safety Group, Stewart Leggett said: “This work is an important part of our safety plan for the A9.
“It will help drivers see more of the road ahead and this will give them a better understanding of what’s happening, improving safety as a result.
“We are focusing on engineering, education and enforcement as we look to improve conditions on the A9.
“A £137 million pounds has been spent on safety and maintenance on the route in the last five years, including work to improve junctions as well as overtaking opportunities, and over the next two years we expect to spend an additional £18 million pounds.”
Eddie Ross, BEAR Scotland’s North West Unit Representative said: “The A9 is a major life line route for Scotland and is seeing a lot of investment in safety improvements in partnership with the A9 Safety Group.
“This landscaping programme of roadside vegetation clearing will give further safety benefits to drivers by improving visibility.
“It will be particularly beneficial once the annual growing season starts.”
