Abstract

A transportable floating bridge includes a bridge unit, a buoyant pontoon for supporting the bridge unit, a device carried by the pontoon for lifting and pivoting the bridge unit, a coupler for swingingly linking the bridge unit to a like pontoon supported bridge unit, and a coupling for rigidly coupling the bridge units together, whereby the floating bridge is easily formed from a plurality of bridge units regardless of whether the bridge units are located end-to-end or side-by-side after off-loading from their transport vehicle.
