摘要 A temporary or permanent bridge is constructed to enable transportation across a waterway. In wartime such a bridge constitutes a bombing target. The object of the present invention is to draw attention to said bridge by creating one or more false bridges one beside the other, each consisting of a frame provided with floating elements (11,16,19 and 22) and a covering layer (23) which, seen from above, give the impression of a roadway.
