Overhaul of the overpass at km 24+478 of the national highway M-04 Znamenka – Luhansk – Izvaryne (to Volgograd via Dnipro, Donetsk)

The detailed design provides for the construction of a new span structure with a bridge deck complex, the construction of new intermediate supports, the construction of end support attachments, and the construction of a connection between the overpass and the approaches.

The main parameters of the overpass after the overhaul:

• prefabricated monolithic continuous span structure according to the scheme 11.38+16.8+11.38 m;
• total length of the overpass – 40.26 m;
• overall dimensions of the structure: G-8.0+2×0.75 m;
• under-bridge dimensions are 7.2 m;
• overpass structures in accordance with DBN V.1.2-15:2009 “Transport structures. Loads and influences. Bridges and pipes” are designed for the action of permanent loads: self-weight of structures, temporary from rolling stock – A11 and NK-80, temporary from pedestrians (as a vertically evenly distributed 0.4 t/m2), wind (characteristic pressure W0=450 Pa), temperature and climatic.
