It's a bit of a "long way round for a short-cut" when you have to go down the hill along the bottom and back up to reach the other end of the road. We've watched the whole process and it narrowly escaped a number Before/during/after Blips merely by being ousted in the early days.
I think I'll, maybe, do a complete "after" of both sides of the block.
Looking at it again, I suspect a car might have got through, but I doubt if "The Wagon" would have made it.
