Reconstruction of the bridge at km 52+692 of the general-use highway of state importance M-04 Znamenka-Luhansk-Izvaryne (to Volgograd city via Dnipro, Donetsk)

Bridge at km 52+692

The bridge is designed on a straight line in plan, the longitudinal profile of the project area is designed with a slope of 17.8‰ in the first run, 17.1‰ – in the second and 17‰ – in the third run with a decrease in elevation from the beginning to the end of the bridge.

Taking into account the design task and the results of a special survey of the existing bridge, the working design provides for the construction of a new bridge.

The main parameters of the bridge after reconstruction:

• structure scheme – 3×21.0 m, temperature-inseparable;
• length – 64.74 m;
• overall dimensions – G-8.5+2×1.25 m;
• loads: self-weight of structures, temporary from rolling stock – A15 and NK-100, temporary from pedestrians (as a vertical uniformly distributed 0.4 t/m2), wind (characteristic pressure W0=400 Pa), temperature climatic;

After the reconstruction of the bridge, the residual resource of the bridge will be 80 years.
