Trim years of overgrowth that block road traffic signs, move the vehicle nearer to the middle/crown of the road.
Road users are pushed evercloser to the contraflow vehicles.
Why is this important?
Huge lorries, now using our A routes, are a constant worry simply size and the overgrowth has there body of the vehicle over the centre line. The growth of county hedges have not been cut or maintained ever, I know of several A routes that have never been maintained in fifty years. It is the responsibility of land owners and the highway maintainence to keep our routes safe.
