Works of art crossing a river - Department of the Territory of Belfort

An engineering structure is a structure which makes it possible to cross an obstacle on a road, rail or inland waterway (bridges, tunnels) but also a device to protect against the action of land or water (walls, covered trench, dyke) and a device for transition between several modes of transport (docks and other port structures).

This layer is an inventory of bridges in a hydraulic impact perspective.
