This paper will describe the design of a temporary emergency floating footbridge, to be made when the infrastructure is destroyed by a flood, hurricane, tsunami or any other disaster. The bridge is made of identical floating modules. The modules are composed of prefabricated elements: two trusses, a pontoon and the footpath. The height of the trusses is integrated with the handrail. The sides of the pontoons are inclined to stack these elements during transport. The modules are assembled at the site. A completed module is fastened to the other modules of the bridge. The completed bridge is floated into position. Thanks to the combination of trusses and pontoons, the deformations under expected loadings are reduced considerately. Structurally the pontoons can be considered as flexible supports for the trussed bridge, spanning between the river banks. Keywords: temporary emergency footbridge, floating, transportable.
