Horsley Hill Landslip
The site is located on the B4058 at Horsley Hill, a few hundred metres to the north of the village of Horsley.
The road runs northeast to southwest, the land falling from west to east, with the road lying on the westerly side of a steep sided valley. The site is within a steep sided, wooded and vegetated valley.
The carriageway became restricted due to a slope failure and prior to the start of the current work was operating as a single carriageway under temporary traffic lights.
Gloucestershire County Council is investing substantially in this scheme to enable the road to be fully reopened, with cabinet approving the £550,000 investment required to make this happen in December 2016.
Because of the extent of the work, the remaining road carriageway at the site was completely removed to provide access to the rock below.
The existing highway surface was planed off and then excavated down to about 2m depth before 94 pre-cast concrete ‘L’ sections were secured to the underlying rock.
The reinstatement of the slip area below the highway will involve the installation of soil stabilisation matting, together with imported topsoil on the slope, with an erosion control blanket covering the slip area.
Work started on 31 July. The road is closed to both traffic and pedestrians at the site of the slip for the duration of the works. A sign-posted diversion is in place.
Initially the work was expected to take around 15 weeks. Unfortunately however, several unavoidable setbacks have been encountered. Severn Trent Water ran into problems diverting the water main and uncharted services were found which together put the scheme behind by four weeks.
Multiple voids under the road were also uncovered, some up to 6.5 metres deep, which needed to be filled causing another week’s delay. As a result of this five week delay the road is not expected to re-open until 15 December.
Please be assured that the team at Graham Construction and Amey are continuing to work diligently to deliver this important scheme as safely and quickly as possible. We apologise for any inconvenience this delay may cause and thank you for your patience.
Horsley is ‘open for business’: the village, its businesses, the school and the nearby Household Recycling Centre are accessible and open as normal.
There is a free shuttle bus service (Route 40 Horsley Shuttle (PDF, 257.2 KB) ) that connects with Route 40 from Stroud and operates when the road is closed between Nailsworth and Horsley for the duration of the works.
