ABSTRACT OF THE DISCLOSURE A stiffening girder for a stayed cable bridge, con- structed of reinforced concrete or prestressed concrete, is formed by a closed multi-cell box extending in the long direction of the bridge. The upper part of the box is a substantially horizontally extending roadway slab. Webs extending downwardly from the roadway slab and in the long direction of the bridge combine with the roadway slab to form at least a part of the multi-cell box. The webs can be vertically arranged or obliquely inclined relative to the roadway slab. Further, a bottom slab spaced downwardly from the roadway slab may complete the box. The girder or box is supported by inclined cables extending in at least one support plane along the long direction of the bridge. The cables can be attached to the girder along its center line in the long direction or at symmetrical locations positioned outwardly from the center line.
