A466 landslip to be repaired


The main road linking Monmouth and Chepstow will be closed from Monday 1 March while crews scale back the fractured rock to ensure the safety of road users.


The A466 Wye Valley just north of Bigsweir Bridge is to be closed for six weeks from Monday 1 March to Friday 9 April.

A rock embankment above the road is fractured and sections are falling onto the highway below. The rock poses a danger to the road and vital improvement works are required to ensure the safety of motorists.

A full 24 hour road closure will be in place during the six weeks so the rock can be scaled back, pinned and netted.

The work will involve scaling the embankment back to remove loose rock and soil. The embankment will then be netted and pinned to prevent any rock falling in the future.

Last year, temporary two way traffic lights and concrete barriers in the centre of the road were installed to protect the single running lane. Following the completion of the works in April, the road will be re-opened for two way traffic.

Cllr Vernon Smith, cabinet member for highways and flood, said: “In the interest of public safety, it is necessary to close this road while our crews undertake the dangerous task of scaling back the fractured rock. I understand the closure is going to cause inconvenience for drivers and local businesses, however this work is significant and much-needed to ensure local residents and visitors from outside of the county remain safe on Gloucestershire’s roads.”

Cllr Patrick Molyneux, county councillor for Sedbury, said: “The A466 is a popular commuter route into Gloucestershire and I’m sure you’ll agree the rock embankment above the road is in need of some urgent attention. I’d like to thank road users and the local community for their patience while this vital safety work is carried out. Please remember to plan your journeys around these closures, as there may be delays and changes to bus times.”


What’s the diversion route?

Social distancing measures will be in place to help ensure our highways crews are safe at all times.
