Opened in 1995, this futuristic bridge stretches in a soaring 2km arch over the Seine between Le Havre and Honfleur. It’s a typically French affair, as much sophisticated architecture as engineering, with two huge V-shaped columns – somewhat reminiscent of giant toast tongs – holding aloft a delicate net of cables. Crossing is quite a thrill – and the views of the Seine are magnificent. In each direction there’s a narrow footpath and a bike lane.
