From an article published on the BBC News web site on 12th November 2004:
Motorbikes and 4x4 vehicles which were damaging one of Britain’s oldest roads have been banned from the area.
The temporary order has been imposed by a number of district councils on parts of the Ridgeway National Trail in south Oxfordshire during winter months.
In previous years the 6,000-year-old trail has been churned up by trail bikers and off-road riders.
