Roadworks which involve closures of the A85 Oban to Perth route at Lochawe get underway on Monday.
Bear Scotland is carrying out £280,000 worth of resurfacing works.
The job will be split in two phases. Phase one begins on October 1 and is expected to take five days to complete.
The upgrade will be carried out between 7am and 7pm each day with the road remaining open. Temporary traffic lights and a convoy traffic management system will be in place to ensure the safety of road workers and motorists.
On Sunday, October 14, the second phase of resurfacing will begin. It is expected to take five nights to complete, finishing on the morning of Friday, October 19. The works will be carried out between 7pm and 7am each night as this section of the A85 will be closed due to the narrower width of the road in this phase.
There will be a signed diversion route in place via the A828 and A82. However, this diversion route is subject to a height restriction of 13’9” (4.2m) at Connell Bridge. All vehicles will be held until able to pass through the works during short amnesty periods at approximately 8.30pm, 10pm, 12am, 2am and 4am.
Eddie Ross, BEAR Scotland’s North West Representative said: “The traffic management arrangements are necessary to keep everyone safe during the improvements, however we’ve arranged for the project to be split into two phases so that we can keep the road open wherever possible during the works, and are only closing the road overnight to further limit the impact to road users.
“Our teams will do all they can to complete the project as quickly and safely as possible.”
