December 2018 marks the 90-th anniversary of the construction (1928) of the world’s first road truss welded bridge (put into operation in August 1929). The bridge designed by Professor Stefan Bryła is a truss bridge with the deck below the arch, having a span length of  27 metres. The article discusses the technical condition of the bridge during non-destructive acceptance tests performed in 1929 and the results of diagnostic tests performed in 1958 and 1960 by the Gdańsk University of Technology and the West Pomeranian University of Technology in Szczecin.
