Nighttime closures of the A85 Oban to Tyndrum road will take place later this month.
The road will be closed for three nights to allow work to take place on a 650ft stretch at Taynuilt.
Work on the £30,000 job gets underway on Tuesday April 18.
Closures will be in place from 7pm until 7am each night.
A diversion will be in place for trunk road traffic via the A82 at Tyndrum, A828 Ballachulish and A85 at Connel. The road will be open during the day.
The diversion route is subject to a height restriction of 13ft 9 at Connel Bridge and as such will be unsuitable for vehicles exceeding this. Vehicles in excess of this restriction are encouraged to plan an alternative route during these overnight works. Or they can wait at Taynuilt to be escorted through the work when it is safe to do so.
Eddie Ross, BEAR Scotland’s north west representative, said: “The resurfacing improvements will help address the defects on the road through Taynuilt and greatly improve the surface for motorists.
“We’ve planned the works to take place overnight and are avoiding working at the weekends to limit the impact on residents and motorists. We’ve carried out consultation with all relevant stakeholders to inform them of our plans.”
