The bridge was built in 2013. The bridge is situated in Kwidzyn over Wisla River. It has a total length 808,4 m and width 15,9 m. The bridge in a six-span arrangement. The lengths of the spans are: 2 x 70 m, 2 x 130 m and 2 x 204 m. To increase efficiency was used a new carrying system – extradosed prestressed bridge. This kind of bridge connected the idea of a suspended and prestressed beam bridge.

Object analysis
The case of study of bridge in Kwidzyn is to research all points where it is possible to find some damages. Generally point of initiation of assessments is structural deterioration. Monitoring of that bridge allows to eliminate all potential damages in qualitative criteria and design value criteria. All sensors measure different value: forces, deformation, or vibrations. The monitoring system collected information in tables or graphs. Also very important is structural analysis. In this case it concerns ultimate limit state and fatigue limit state. The physical intervention of that bridge is repair, strengthening or upgrading.
Object state
The bridge over Wisla River was constructed generally for roadway use. The most important damage for this bridge is excessive deformation and geodetic conditions. It is very important for dynamic behaviour of the bridge. It is used six performance indicator: deformation of steel and concrete, angular displacements, forces in pylons, vibration acceleration, wind speed and direction and other loads (e.g. temperature). The signal of sensors could monitoring dynamic response. This leads to reduction risks of the deformation.
