The complexity of the site, with a water main buried below the road surface, has required extensive investigations to develop a solution to support the collapsed earth bank and road.
Construction is expected to start in summer 2026, following a procurement process to appoint a specialist contractor.
Following a procurement process, CT Construction has been appointed to carry out the repairs.
Based at Chinley in the High Peak, the contractor has worked on a number of previous projects for us including the River Noe retaining wall reinstatement and ground stabilisation works on the A6187.
Start of works
Initial preparations will involve creating a secure compound for the site office, welfare cabins and the storage of equipment and materials.
Work will start in late July 2026 on the site clearance works, creating access ramps on the slope for machinery and equipment to be able to get to work.
The landslip site repairs are expected to take up to 20 weeks, until approximately November 2026, subject to any unexpected issues on site and good weather conditions. Final works will involve road repairs and the construction of a new road drainage system in January 2027.
Work programme
Due to the complexity of the project, we've developed a detailed work programme.
Subject to weather conditions and site issues, the works scheduled to take each month include:
July
Our contractor sets up the site compound and builds the access ramp to safely move equipment down the steep slope to the piling platform.
August to October
Our contractor will install 135 micro concrete piles up to 13 metres deep into the ground at the base of the slope.
They're designed to provide a strong foundation to support the weight of the hillside above.
November
A 54 metre long concrete cap will be built above the concrete piles to make sure the foundation remains stable.
A breathable geocell membrane will then be laid on top of the earth bank.
Topsoil will be laid over the membrane and the slope will be seeded with grass to restore its natural appearance.
December
Our contractor will remove their equipment from site and Derbyshire Highways will start work to rebuild the stretch of road, pavement and boundary wall next to the landslip site.
A new drainage system will also be built to collect surface water from the road. The drainage system is an important part of the repair programme to minimise the amount of water flowing into the slope, to avoid any further landslips.
January
Subject to weather conditions, Derbyshire Highways will complete the works and the road will reopen.

Background
Following very wet weather conditions, Leashaw at Holloway was closed in November 2022 due to a major landslip. The landslip damaged the road and pavement.
This part of Derbyshire is prone to landslips in wet weather conditions, due to the underlying geology of clay and shale, which once saturated, can cause ground to move downhill, due to gravity.
The repairs required at Leashaw are complicated due to the proximity of residential housing, and the many utility services contained within the road, some of which were affected by the landslip or had the potential to be damaged by any further movement.
We've worked very closely with National Grid, Severn Trent Water, and Cadent Gas to allow remedial work and diversions to be installed to ensure the integrity of their services and continuity of supplies to the community.
Regular monitoring of the road has detected signs of further movement after wet weather. Unfortunately, this has meant it has not been possible to open up one side of the road to light vehicles as had been hoped.
An independent road safety audit commissioned to look into the reopening plans raised some concerns about further ground movement, as well as how to ensure safe access for all road users.
Specialists have been commissioned to look at a long-term plan to carry out permanent repairs to the landslip which would enable the road to be fully reopened.
Following the announcement of new funding from the East Midlands Combined County Authority (EMCCA) in 2025 for a multi-million-pound repair scheme, work is now in hand to start on site in summer 2026.
The project looks likely to involve a circular piled solution, with concrete beams, faced with a stone retaining wall to support the ground, road and utility pipes to prevent a further landslip.
Information from ongoing ground monitoring reports will be used to finalise the plans, with procurement to appoint a contractor to start later this year. Discussions with landowners will also need to take place to secure agreement for the works.
Due to the road closure at Leashaw, the diversion route is Yew Tree Hill, Mill Lane, Lea Road, Mill Lane, A6 Derby Road to Whatstandwell, B5035 Main Road, Sandy Lane, Bowns Hill, Cromford Road.
