Under the road reconstruction project it was prescribed to replace the existing superstructure of the bridges across the Sozh River with keeping existing piers. The new superstructure is composite beams with 11.5m-wide deck and two 1.0m-wide footpaths. The river bed part of the bridge is continuous 83.31+83.84+83.31m spans; the riverside part is split with designed 42.0m-long span.

This bridge is built on the bypass of Vitebsk City. The river under the bridge has strong current and the depth is 8m. The height of the piers is approximately 30m. The bridge has 63.0+126.0+63.0m spans. The superstructure consists of two steel continuous girders with box cross section, connected with reinforced concrete slab and lateral bracings. The front wall of the box cross section is inclined and in the inner side of the superstructure it is vertical. The height if this box is 3180mm and the width of the upper chord is 2600mm.
