The footbridge Richerand crosses the pond of the Marais of the Saint-Martin canal at the level of the avenue Richerand in left bank, and of the street Jean-Poulmarch, of the street of Marseille and the street Beaurepaire in right bank. The footbridge is established by two big reconstituted welded beams forming crutches and lifeline of the apron, the staircases of access are half fitted out on piles of masonry on both sides of the canal and half between the big beams.
