	Summary:
	This paper presents damages, problems and repair solutions of reinforced concrete bridge over the river „Belica“ at KM 711 +351.49, right lane of motorway E-75, Belgrade –Nis. The original bridge section was designed for arterial (main) road capasity and it was widened to the motorway section. Significant damages of concrete and reinforcement in the zone of longitudinal ( joint of original bridge and widening) and transverse dilatations were noted by inspection . Long-term exposure to water, frost and salt caused damage of protective concrete layer, corrosion of concrete and reinforcement and separation of rebar reinforcement from concrete, which reduced bearing capacity of structure and jeopardized safety of traffic participants. Removal of longitudinal dilatation and monolithization of the both existing structures in one with repair of all damages at bridge was performed by proposed repair solution.
