Grudziadz Bridge Poland

Grudziadz Bridge is a pre-stressed concrete bridge which crosses the Wisla River in Grudziadz, Poland. The whole length of the bridge is 404 m, with span lengths of 110 m, 180 m and 110 m. The used construction method is free cantilevering. The maximum cantilever lengths reach up to 94 m in the side spans and 89 m in the central span. During the construction two temporary piers were used which were placed only in the side spans 22 meters away from the pier. The cross-section is a single cell hollow box which has a varying depth from 4 m at mid-span to 10.5 m above the piers.
