The footbridge was built in 2019 over Kamienica River. It was built as part of the European network (EuroVelo cycle routes). It has a span length 78 m, usable width 2,5 m and maximum height of structure 10 m. The deck (panels) of the bridge is made from hybrid concrete-composite. The material which was used to panel performance is FRP polymers.

Object analysis
The footbridge in Nowy Sącz is convenience for residents. The case of study is to research all points where it is possible to find some damages of bridge. Generally point of initiation of assessments is research interest. Monitoring of that bridge allows to eliminate all potential damages in qualitative criteria. The integrated structural monitoring system was built primarily on the composite EspilonRebar strains sensors. They are made in the form of GFRP reinforcing bars and connected within composite deck panels. Also very important is structural analysis. In this case it concerns ultimate limit state. The physical intervention of that bridge is repair.
Object state
The footbridge over Kamienica River was constructed generally for pedestrians or bikers use. The most important damage for this footbridge is excessive deformation. It is very important for dynamic behaviour of the bridge. It is used three performance indicator: deformation and other loads (e.g. temperature). The signal of DFOS sensors could monitoring dynamic response. This leads to reduction risks of the deformation.
