Special features

Pedestrian bridges are a familiar part of our environment. Often marked by strong architecture, they symbolize a town, a district or a freeway rest area.

The total operating overload, naturally much lower than that of a road bridge, leads to the use of construction elements with modest dimensions and thicknesses, but appropriate to the structure.

Footbridges are therefore slender, lightweight structures that can withstand all ground conditions. Their assembly, usually by crane, poses no particular problems. Since the conditions under which a footbridge is built do not have the same impact on the project as they do for a road or rail bridge, it is possible to dispense with them and give precedence to architectural expression.
