A section of the A65 will be closed overnight for four weeks of essential repairs.
The closure is necessary to fix significant roadside damage caused by an accident involving an overturned HGV, which left the westbound carriageway unsupported.
The damaged site, situated between Crooklands roundabout and Nook, has been under temporary traffic control since the incident, allowing the route to remain open.
The closure will start on Monday, September 23, and will last for approximately four weeks.
The affected section of the A65 will be closed from Monday to Friday between 8pm and 5am.
This will allow Westmorland and Furness Highways, and its contractor, to construct a retaining wall approximately 35 metres in length.
The size of the equipment required for these works means that vehicles, pedestrians, and cyclists will not be able to pass through the site during the closure times.
Emergency services, postal and refuse services, and bus operators have been informed and consulted about the closure to ensure services are not impacted.
Councillor Peter Thornton, Westmorland and Furness Council cabinet member for highways and assets, said: "This section of the A65 has been under traffic light control for several months to keep the road functioning safely for local communities and freight traffic while we worked to establish a solution for this issue.
"It is good news that these essential works to make this vital route safe to be fully reopened have now been confirmed to start on Monday, September 23.
"We understand the closure will be frustrating for those who use the road regularly and have carefully planned works to take place overnight to reduce the impact of the closure.
"We apologise for this inconvenience this will cause and kindly ask road users to follow the signed diversion route so works can be completed as quickly and efficiently as possible."
All road users will be required to follow a signed diversion route, which can be viewed on the One Network Map on Westmorland and Furness Council's website.
