On main road M-1.12, section Niš – Dimitrovgrad, there is a reinforced concrete bridge over Nišava river. It was designed in 1971 at The Highway Institute, and built afterwards in the period 1972 – 1973. The bridge is a continuous frame construction with three fields, and distribution of spans 10.4 + 20.8 + 10.4 m.

In the course of operation lasting many years, due to inadeqaute maintenance, caused considerable damagas which occurred on the facility. Upon Employer’s request, in the year 2006 Main repair design was prepared, but the repair has not been carried out as yet. Due to the preparation of Main design of E-80 motorway, Niš-Dimitrovgrad, it was required to widen both the alignment of existing main road M-12 and existing bridge itself. With Main design of the bridge over Nišava river, i.e. on the right carriageway of E-80 motorway, bridge widening to the required motorway profile, as well as necessary repair measures of the structure have been anticipated.
