City bridge over the Ishim River with 8 traffic lanes. Clear roadway of bridge – Г (0.5 x 3 +4.5 +2.0 +4 x3.5 +0.5) + two sidewalks of 3 m each. Over-water length of the bridge is overspanned by an arch span with a design span of 151.2 m. This arch structure is a combined system without horizontal thrust with a roadway on bottom boom – a flexible curve with a rigid tie. The camber of arch is 30 m. The arch is combined with the roadway by means of a flexible suspension system, where the suspension system consists of two planes in each arch. The bridge is a doubled arch in its cross-section and consists of two arches inclined to the vertical at an angle of about 30°. Inclined arches are combined with each other by means of rigid spacers in order to provide for plane stability. Those arches support the steel-reinforced concrete roadway by means of hangers. The height of binding beams is 3 m. The hangers are cable-stayed elements consisting of 12 strands.
