As shown in the drawing, the point of the innovation is that the ends of the strutting are recessed corresponding to the roadway section, overlap and are fixed by a U-bolt which grips around the support section, fixes the structure spacings and forms a frictional connection via the hexagon nuts (6) and (7). As a result of the overlapping, no further lugs or the like are required. <IMAGE>
