PART of the Ridgeway National Trail in near Avebury will be closed to motor vehicles over the summer months to enable repairs to be carried out.

The first few miles of the Ridgeway National Trail lie within the Stonehenge and Avebury World Heritage Site between Overton Hill and Hackpen Hill.

A spokesman for Wiltshire Council said: “This section is in need of repairs to the surface. This part of The Ridgeway is a Byway Open to all Traffic, which means that motorised vehicles can legally pass along here. Use by motor vehicles has caused considerable rutting of the surface, making it difficult for all types of users to travel and damaging internationally important archaeological features.

“It is difficult to know how much and what type of vehicle traffic the local materials can withstand, so an experiment will be carried out.”

In order to protect the surface during the wettest months of the year, a seasonal Traffic Regulation Orderprohibits motorised vehicles from using this stretch of the route throughout the winter months, between October 1and April 30.

But this year, from May1 to September 30, a temporary order banning motorised vehicles will be put in place.

A council spokesman said: “Walkers, cyclists, horse riders and horse and carriage drivers will be able to continue to use the route at all times.

“The order will be in place during the summer solstice celebrations, but the first stretch of the Ridgeway and byway Avebury 5 will be open for public access as usual.”

From next May the order will be lifted but some vehicles may still be banned.

Bridget Wayman, Wiltshire Council cabinet member for highways, said: “It’s important we do all we can to protect this area with its archaeological heritage. We believe the measures we will be putting in place are appropriate.

“We apologise for any inconvenience.”
