Damage of spans of the overpass caused by impact of underpassing vehicles are a frequent case. Objects that use prefabricated load-bearing elements that are not designed for such impacts are particularly exposed. After impact, such parts suffer extensive damage that need repair. Taking advantages of this recovery actions it is worth to perform strengthening that will protect object against possible future impacts. In this study the influence of the structural strengthening of the damaged overpass on its strength parameters is investigated. For this purpose the advanced computational model was created. The model includes reinforcement and prestressing tendons. This model enables reliably restore damage caused due to the vehicle's impact and analysing of re-impact the strengthened structure. The damage of the concrete and deformation of the reinforcement is presented.
