The Vistula River Bridge near the city of Grudziądz in Poland carries a major national motorway across Poland’s longest river. The structure, which opened to traffic in 2011, is the longest bridge of its kind in Poland, with a total length of almost two kilometres. The main part of the bridge, excluding approaches at each end, has a main span of 180 m and side spans of 110 m each. The northern approach has 21 spans and the southern one has 12 spans, each approximately 50m long. The main span was constructed by the cantilever method (overhang concrete pouring).
In 2010, mageba supplied four TENSA-MODULAR expansion joints for the construction of this bridge – two with eight movement gaps each for one end of the bridge, and two with nine gaps each for the other end. All of the joints feature noise-reducing surface plates (“sinus plates”) which provide a continuous driving surface, avoiding wheel impacts and thus minimising the noise from over-rolling traffic. The mageba designations LR8-LS and LR9-LS indicate, with the suffix “LS”, that the joints feature noise-reducing surfacing.
