The bridge was built in 2015. The bridge is situated in Blazowa (South-East Poland) over Ryjak River. It has a total length 22,3 m and width 10,54 m. The bridge span is single-span facility. This bridge is very innovative. It was one of the first composite bridges in Poland. The span of the bridge is made of composite girders, connected with the lightweight concrete deck slab.

Object analysis
The case of study of Blazowa Bridge is to research all points where it is possible to find some damages. Generally point of initiation of assessments is research interest. Monitoring of that bridge allows to eliminate all potential damages in qualitative criteria. All optical fibres sensors is situated in girders. Also very important is structural analysis. In this case it concerns ultimate limit state and acoustic emission. The physical intervention of that bridge is repair or upgrading.
Object state
The bridge over Ryjak River was constructed generally for roadway use. The most important damage for this bridge is excessive deformation. It is very important for dynamic behaviour of the bridge. It is used three performance indicator: deformation, other loads (e.g. temperature) and acoustic emission. The signal of sensors could monitoring dynamic response or visual inspection. This leads to reduction risks of the deformation.
