MOTORISTS using the A361 into and out of Devizes are facing long delays.

A three-way traffic light signalling system near Wadworth is causing congestion.

Some impatient drivers have been seen turning round in a bid to find alternative routes.

One witness said: "There's lots of traffic stuck at Caen Hill coming into Devizes. There's lots of people turning round."

Drivers on the M4 near Junction 15 and holiday traffic on the A303 at Amesbury also face delays.
