Abstract
A bridge of the cable-stay type, in particular of a very large span, the deck of which is supported by stays deflected by passing over towers (21). Some of the stays (22) are anchored on the deck at two points of the deck situated on either side of a same tower (21), and the central part of a span between two towers is supported exclusively by other stays (25) which, after having been deflected at the top of a tower, are each anchored in an anchor block (26). The tensile stress to which the central part of the deck is subjected under the effect of these stays (25) directed towards the tops of the two towers situated on either side of the span is compensated for by an axial compressive prestress.
