Kirkstone Pass will close for up to three weeks from Monday.
Contractors will move in to continue work on a multi-million-pound road safety project on the iconic Lakeland route.
The improvement scheme restarted earlier this month following a planned break to avoid any disruption during the school summer holidays.
Work is continuing under traffic light controls, but drivers are reminded that the next full closure, which will be for a maximum of three weeks, will start on Monday, October 2.
The road will reopen again ahead of the school half-term holidays at the end of October.
During the October closure, contractors working on the scheme will be excavating the entire width of the carriageway to support its full reconstruction.
After October half-term, work will continue under temporary daytime traffic lights and some overnight closures leading up to Christmas.
The future overnight closures are planned for the following dates Monday to Friday from 9pm until 7am (weather permitting):
- Monday October 30 until Friday November 17: For drain repairs and to begin installing new crash barriers.
- Wednesday December 6 until Wednesday December 20: To allow further installation of new crash barriers, undertake more drain repairs and to make the road safe before works are stood down for Christmas.
- Wednesday January 3 until Friday January 19: To enable the contractor to continue with the installation of new crash barriers and further drain repairs.
A further full road closure is scheduled to take place from March 1, to complete the resurfacing work. This closure will now span over four weeks, subject to weather conditions.
The ongoing Department for Transport Safer Roads Project, managed by Westmorland and Furness Council, includes building new drainage and culverts, resurfacing and installing new environment sensitive wooden-clad safety crash barriers and ‘catchpits’ to collect scree washed off the fells.
More than 200 metres of new stone walling has so far been created, along with improved signage and three new lay-bys.
The work will help to protect the road from the effects of flooding and adverse weather and increase the safety and resilience of the route, especially during winter, resulting in fewer enforced closures in the future, the council said.
Careful planning means the works have been scheduled around the busiest school holiday periods, to minimise the impact on tourism businesses in one of the most popular areas of the Lake District.
All roadworks on Kirkstone Pass were removed before the start of the recent school summer holidays and the road was kept fully open during the busy holiday period.
Work is also currently taking place under traffic light controls to support essential bridge repairs at Cow Bridge.
