🚧 Rushmire Hill is now open! 🎉 We’re pleased to announce that all works are now complete and the road is fully open to traffic. Thank you for your patience during the construction period. Please note, there will be a one-night closure on Monday 28 July 2025 to carry out final defect works—after that, it’s smooth driving ahead!
The B4058 carriageway on Rushmire Hill has been affected by cracking and subsidence since it was first inspected in September 2016. Since this first inspection, Ground Investigation has been undertaken in 2018 and 2023 to monitor movement and install groundwater and ground movement monitoring equipment.
The site has deteriorated over the last seven years and has been resurfaced multiple times. The cracking at the site runs parallel to the verges and is mostly located along the northbound lane of the B4058. There is also cracking in Old London Road and the southbound lane of the B4058. Cracking and areas of resurfaced patches, which indicate locations of historic cracking, extend across the full length of the site.
The B4058 is a key route within the county and connects Wotton Under Edge with areas to the north and west, such as Nailsworth, Stroud and Tetbury. Intervention now will prevent further movement and the risk of more catastrophic failure.
The B4058 carriageway on Rushmire Hill had been affected by cracking and subsidence since it was first inspected in September 2016. Following this initial inspection, Ground Investigations were carried out in 2018 and 2023 to monitor movement and install groundwater and ground movement monitoring equipment.
Over the past seven years, the site had deteriorated and was resurfaced multiple times. Cracking, primarily along the northbound lane of the B4058 and also present in Old London Road and the southbound lane, was observed to run parallel to the verges. Resurfaced patches, indicating historic cracking, extended across the full length of the site.
As a key route within the county, the B4058 connects Wotton-under-Edge with areas to the north and west, including Nailsworth, Stroud, and Tetbury. Intervention at this stage was necessary to prevent further movement and reduce the risk of more severe failure.
What Did We Do?
Based on the collected data, an engineering assessment and repair options report was compiled. Although monitoring did not fully confirm a deeper-seated failure mechanism, a conclusive assessment would have required significantly deeper ground investigation—beyond the 17.5m depth of existing boreholes—and would have exceeded available budgetary resources.
A medium-term solution was therefore implemented, involving the installation of a 255m-long, 9m-deep sheet pile wall to support the road and stabilise the slope. This approach was assessed as the most practical remediation option. Given the natural topography underlying many roads in Gloucestershire, similar risks are managed across the network. Post-construction, the road will continue to be monitored for further ground movement.
Works Progress
The contractor, Montel, mobilised to site and began the project as scheduled on 6 January 2025.
The arrival of the piling rig, crane, and sheet piles marked a significant milestone, and piling operations officially commenced shortly thereafter. These works were essential to stabilise the road and ensure its long-term safety for the community. The road remained closed during this period, with a diversion route in place.
We’re pleased to confirm that the works have now been completed and Rushmire Hill is fully open. Thank you for your patience and support throughout the project.
Please note: there will be a one-night closure on Monday 28 July 2025 to carry out final defect works.
Why?
We are responsible for maintaining roads across the county. This is one of several sites identified for repair to ensure the safety of road users and to reduce future maintenance costs.
