Four sets of roadworks planned for same road
Westmorland and Furness CouncilFour sets of roadworks on a 10-mile (16km) stretch of road are expected to bring disruption to motorists over four months.
Westmorland and Furness Council will start work on the A684 between Sedbergh and Garsdale Head in South Cumbria on 22 June.
The schemes will look at rebuilding collapsed retaining walls and reconstructing river culverts, which the council said were "vital to protect the road from landslip damage, flooding and carriageway collapse".
A spokesperson at the Liberal Democrat-led authority said they acknowledged the frustration "to have so many closures on this stretch of road over this period", but said the repairs were "essential".
The authority had initially planned to stagger the roadworks across a longer period of time, but it wanted to avoid work on the A684 while it was being used as a diversion route during the Dent Head landslip repair works.
The schemes involve reconstruction of the River Clough retaining wall between 22 June and 17 July during the first phase.
A second phase, expected to last three weeks, will take place in July or August to repair the culvert retaining wall at Smorthwaite.
In September, works will move to reconstruct the Bellow Hill culvert and fix drainage issues between Long Holme and the entrance to West Bridge End.
These are expected to last five weeks.
Finally, the Potgill Holme cattle grid is due to be replaced in October, with disruption expected for a maximum of three weeks.
Exact dates are being finalised and will be firmed up soon, the council said.
Full closures of sections of the A684 will be necessary during parts of the work, but additional temporary restrictions are planned on adjacent roads to prevent "rat running" away from the signed diversion route.
The spokesman said: "We have planned the works and staged the closures as much as possible to mitigate the impact on local communities and have introduced measures to ensure the safety of residents and all highway users while the repairs are carried out."
