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.
The project was completed ahead of time and on budget.

2. Why are the improvements necessary?
The improvements are necessary to prevent further disruption from landslip movements that have affected the carriageway for a number of years. The main purpose of the scheme is to fulfil the following objectives:
- 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.

5. Why can't these funds be spent on routine maintenance, such as filling potholes?
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.
