Thirlmere West Road and Rough Crag
Updated: 21st May 2024
A section of the West Road at Thirlmere was temporarily closed beneath Rough Crag for safety reasons between 2021 and 2024, following storm damage. You can find out more here about the specialist engineering work we carried out to stabilise the crag so that the road could reopen in May 2024.
Rough Crag is around 100 metres in height with a 60 metre face sitting directly above the West Road. A number of mature trees growing from the crag were loosened during storms with the root plates lifting and dislodging the rock face behind. Some material fell down the face and onto the road, and a significant amount of loose material remained suspended directly above the road, presenting a major risk. A specialist project was needed to make the crag safe again.

TIMELINE OF ACTIVITY



This week we were able to reopen the lakeshore footpath below Rough Crag, so walkers can now use this route to navigate a full circuit around the Reservoir. We’ve based this decision on the results of the surveys undertaken before Christmas which have given us reassurance that the footpath is safe for use.

Our forestry team and contractors have been clearing the last group of pine trees which had fallen across the West Road. These were within the high risk section of road which is closed.
Engineering specialists accessed the top of Rough Crag via a safe walking route with one of our forestry team to carry out a 3D survey. They used a drone carrying specialised “LIDAR” (Light Detection and Ranging) equipment which uses pulses of light to accurately map the rock face in 3D. This will help to pinpoint exactly where all the cracks are in the rock face and identify any loose boulders or trees, allowing engineers to develop the best course of action to make the Crag safe.
