New construction of Dona Aminado Street in Kropyvnytskyi (Stage 1 of the construction site)

The work area is located in Kropyvnytskyi, Kirovohrad region.

The project provides for the construction of a new bridge with the following main parameters:

• prefabricated monolithic temperature-continuous span structure

according to the scheme 4×24.0 + 4×24.0 m;

• intermediate supports – reinforced concrete columnar on a pile foundation;
• end supports – single-row piled reinforced concrete;
• total bridge length – 193.7 m;
• the bridge structures are designed for the following loads: self-weight of the structures, soil pressure of the embankment, temporary loads from rolling stock – A15 and NK-100, temporary loads from pedestrians (as a vertically evenly distributed 0.4 t/m2), wind, temperature and climatic loads.

Taking into account the design tasks, as well as the requirements of Amendment No. 1 of DBN V.2.3-4:2015 in terms of the designation of the gauge, the working design must provide for:

1) the arrangement of a carriageway gauge with a width of 7.0 to 7.51 m, consisting of two lanes, each 3.0 m wide, as for a main street of citywide significance (district significance), which passes through a settlement in which a speed limit of up to 50 km/h and safety strips of 0.5 m on each side are in force;

2) arrangement of a sidewalk on one side, 1.81 m wide, and a bicycle path on the other, 3.21 m wide.

Ensuring the reliability and safety of a linear object of engineering and transport infrastructure (a bridge over the Ingul River) is carried out by complying with the requirements for mechanical resistance and stability, fire safety, limiting the threat to human health and harmful effects on the environment, as well as safety and accessibility in use.

The estimated service life according to DBN V.1.2-14:2018 and DBN V.2.3-22:2009 is 80 years.
