A46 Coopers Hill landslip

Time lapse video

The A46 connects Stroud to Gloucester and the Brockworth Bypass. Approximately 1km south of Brockworth a small section of the A46 on Coopers Hill, known as the 'southern corner', and was suffering from subsidence caused by landslips.

Highways engineers fixed the landslip to prevent the road from becoming dangerous.

The project was completed ahead of time and on budget.

What did we do?

The work involved drilling into the ground and filling the holes with concrete and reinforced steel structures. Forty-two of these foundations were installed, reaching a depth of 12.5m and placed along a 90m area.

During the works new sections of drainage were installed and the highway was fully reconstructed. Contractors Walters UK LTD were appointed to carry out the scheme.

Reduce the risks to motorists from landslip movements which result in damage to the infrastructure.
Improve the layout of the carriageway whilst also improving surface water systems to improve motorist safety.
Improve the route for public transport and cyclists.

Department for Transport funds are allocated for capital programmes to improve the highway infrastructure rather than routine maintenance.

6. Have you considered the potential environmental impacts of the scheme?

Yes. Site survey work is carried out in order to assess the potential environmental impacts, and how the scheme design can mitigate these. The environmental assessment will consider all the environmental impacts of the scheme, and how these are to be mitigated.
