Crucial repairs set to stabilise popular road at Cannop in the Forest of Dean

Published

Important geotechnical repairs to stabilise the B4234 at Cannop will begin this May with a short diversion for traffic while the major improvements are made.

The stretch known locally as New Road between Cannop and Parkend has been unstable for some time as the land is slowly slipping underneath.

The road has been kept open using traffic lights to help vehicles avoid the worst sections of the road slip, whilst engineers have been designing a permanent repair so the road can reopen to two-way traffic.

To make the road fit for the future more than 100 giant steel screws known as ground anchors will be put into the embankment to hold the road securely into the underlying bed rock.

For the safety of local people it will be necessary to close the road to traffic from 9th May for the duration of the work.

A signed diversion will be in place marked with a triangle. This will be along Speech House Road to the junction with Russell's Lodge then along Fancy Road and onto Cannop Road.

During the first four weeks of the closure the drainage system throughout the site will be rebuilt and then the main stabilisation work can begin.

The county council is working with the Forestry Commission to make sure the construction work will have as little impact as possible on the surrounding woodland.

The work must be carried out over the summer months when the ground water is at its lowest level. The road runs alongside Cannop ponds and during the winter the water levels in the ponds come right up to the edge of the road covering the area where the work needs to take place.

The improvements are expected to take around six months to complete and it is planned that the road to reopen in time for Christmas.

In the 12 months after the work has taken place, extra resurfacing has been planned along the road to remove any carriageway cracking that could be created by the planned tensioning of the ground anchors in the embankment.

Gloucestershire County Council has invested £850,000 to make these major road improvements in the Forest of Dean.

Cllr Vernon Smith, cabinet member for highways said, "This is really important work to make sure this Forest road is protected from future slips. By using ground anchors in the embankment we can hold the road securely to the underlying bed rock and make the road much more stable.

"A small diversion will guide vehicles around the work and I'd like to thank residents and visitors in advance for their patience while the improvements are made."

Cllr Richard Leppington, local county councillor for Blakeney and Bream said, "I am pleased that this work is now taking place."
