Essential safety work due to subsidence on the A466 road between Chepstow and Tintern means that Monmouthshire County Council will install a set of traffic lights north of the former Livox Quarry entrance. Lights will operate from Monday 9th October until the end of the month and will allow the council to carry out ground investigations and bore-hole drilling. The investigations will provide vital data so that the council can eventually stabilise the carriageway by realigning the road into the adjacent hillside.

The lights will be relatively close to another set near the Livox quarry entrance – a result of a rock fall – so to minimise disruption both sets of lights will be manually controlled during work hours until the council is confident they can be operated automatically. If issues arise the lights will be returned to manual operation until site investigation works are complete.

Monmouthshire’s cabinet member for county operations, Councillor Bryan Jones said: “Motorists may be frustrated by the temporary addition of another set of lights on the A466 but the geology and nature of the surrounding area requires us to ensure safety is paramount until we can arrive at a permanent solution for this stretch of the road.”

A further set of lights on the A466 close to the Wyndcliffe picnic site will continue to operate, again for safety reasons following a rock fall and difficult geological conditions.
