Abstract: A modular pedestrian bridge (10) is disclosed. In its simplest form, the bridge (10) includes: a span module (12) having a tunnel (14) sufficient to allow pedestrians to travel through the tunnel (14), the tunnel (14) being defined by a floor (16) and a top (18), defining a height (20), sides (22) defining a width (24) and upper and lower connectors (26) and (28), a tower module (30), a stair assembly (32), the tunnel (14) having sufficient dimensions to allow the tower module (30) to be telescopically fit into the tunnel (14) and the span module (12) being adapted to fit on a chassis or flat bed truck of a vehicle. The bridge (10) is configured to simplify assembly and disassembly and is adapted to fit on a chassis, flat bed truck and the like. The span module (12) is dimensioned, such that it does not have special freight requirements, possibly triggering state and federal escort laws for extra wide or long loads.
