The bridge is passable on the cycle lane but I strongly recommend riding on the pedestrian section to avoid overtaking at high speed on the climb.

There is an existing cycle path, but there is only a white line separating vehicles at 90 km/h. Danger.

The tower once stood as a lighthouse in the former harbor entrance. Today, a road surrounds it.

Not exactly a good idea in terms of driving technique - a narrow, divided footpath and cycle path, but separated from the car lane by a curb. Trucks generate a noticeable suction. You may have to push if there is a strong crosswind. But you get across the wide Seine estuary and have a great view!
