Gravel biking around Réserve naturelle de l'estuaire de la Seine
It goes about 1km uphill at a constant 6%, and on the other side about 1km downhill at 6%. And the architecture of the bridge is impressive, the view in good weather great. But the cycle path is simply dangerous. I was very surprised that there is a cycle path, because it is perhaps only 1-1.2m wide, and is only separated from the car and truck traffic, which rushes past at 80-90 km/h, by a white line on the asphalt. Certainly no cycling pleasure. And given the quite strong winds that can make you swerve, it is also not entirely harmless. There is also an almost equally narrow footpath next to it, but it is separated from the roadway by a curb (at least). The crossing of the bridge would certainly be a highlight of any bike tour, but the incredibly narrow strip next to the fast-flowing traffic does not make it a real pleasure.

Amazing city crisscrossed by multiple canals or streams of the Risle.

If you're afraid, you can also push it on the sidewalk. Plenty of space for that. There's still an unpleasant km to Le Havre until the exit, but at least it doesn't go uphill.

The cycle path is very narrow and not physically marked, very dangerous. It is better to use the pedestrian path.
