The article presents a description and analysis of the causes of damage to a road viaduct, made of prefabricated compressed beams of the WBS type in the 1970s. Both the design and damage are typical for objects made in those years. Damage results from the deck slab being too thin, low quality waterproof membrane, easily deformable deck surface, leaking bridge deck expansion joints, linear-contact bearings at excessively long spans, undurable drainage system elements. On the basis of the static and strength analysis, proposals for a way of repairing the viaduct were given, which, taking into account the occurrence of similar structural solutions in existing facilities, can be used as a guide when designing renovation and modernization.
