https://doi.org/10.4467/2353737XCT.15.158.4333The present paper is related to the motorway overbridge, the technical state of which has been showing deficiencies related mainly to the presence of cracks. Verification of the design and construction documents was carried out prior to advanced analysis which covered the construction process with phases, loads acting in various periods of time as well as the progressing ground deformations. Conclusions drawn on the basis of the analysis results are not typical because the emergency situation is resulting from many simultaneously acting factors. The level of the reduction of the safety margin of the bridge has been estimated.
