Carolyn,
You are quite right, we don't relly need any more studies on 'Roads To Hell.' We all know the features benefits and implications of concrete and tarmac. We all know the environmental devastation caused by accommodating the car.
No matter what has been said, by the Conservatives, it is little more than quibble. If you want local councillor support for this road (and I'm sure some do) then vote Conservative or LibDem. If you don't, then don't.
