If you take the Eurotunnel and get onto the A16 for Paris, after a short while (within the first half hour) the road crosses a large blue bridge, over a river I think. Does anybody know exactly where this bridge is, or a google map ref for it? Thanks.
Also the scene of many a speed trap set when heading south: they point the camera at you as you start to traverse the bridge and fine you just before or after the toll. R.
