When politicians facing a tough re-election campaign in five months’ time pose for the cameras at Stonehenge to announce a 15-year spending plan, it looks more like electioneering than a serious transport policy.

By backing a new version of the tunnel which is both unaffordably expensive and incredibly damaging to the Stonehenge landscape, Cameron and Clegg promise us more years of argument before (probably) someone cancels it again.

The Conservatives probably made the right decision in 1996 when they accepted the recommendations of the round table conference at the Red Lion, but in view of the cost decided to drop plans to dual the A303.

Two decades on, the cost has more than doubled and it would be a complete waste of money even if they could get it right.
