ABSTRACT:
A tension-band bridge having one or more main openings (2) and possibly subsidiary openings (3), comprises a tension band (4) gripped between abutments (5) and possibly taken over supporting pillars (6). The traffic route over the bridge is disposed on a saddling (7), which bends in the longitudinal direction of the bridge, in the region of the main openings (2), while the tension band (4) can be travelled over directly in the region of any subsidiary openings (3) which may be present. The saddling which bends in the longitudinal direction of the bridge preferably consists of a latticework construction (10, 11, 12) which is rigid in the transverse direction of the tension band (4) and which is connected, in the longitudinal direction of the bridge, by means of diagonal struts (13) in each of which shock absorbers (14) are disposed.
