I won't rant here, not a lot of point. Have signed petition for now ... and will watch for anything further that can be done to influence the council's decision. I find it hard to believe they would consider widening that road for heavy traffic as it is used by pedestrians crossing from one side to the other.
Edit: On second thoughts pedestrians crossing doesn't seem to make any difference to heavy traffic (including HGVs) at Avebury.
