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 river crossing structure is 28km away from the downtown. The width of the river under the bridge is 589m. The total length of the bypass of Krasnoyarsk is 32.3km. The project includes construction of 11 bridges and viaducts, including this bridge across the Yenisei River. The bridge has 33.0+(126.0+231.0+126.0)+3x63.0+3x33.0m span. The total length of the bridge is 814.3m. It also has 2-lane carriageway, which width is 11.5m. River bed piers are constructed for full development, for 4-lane carriageway. The river bed part of the bridge is the half through truss with 126+231+126m 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.
The viaduct of the junction in Nizhnevartovsk is located above the road from Nizhnevartovsk to Izluchinsk. The skew is 62°. The viaduct is designed as a frame structure with 16,6+22,6+16,6m skew spans. The total width is 15.4m. The length between abutments is 65.6m. The width of the deck is 11.5m with two 1.5m-long footpaths. Obstruction clearance varies between 6.4m and 6.8m.
The viaduct has 7х18.0+3х21.0+54.0+2х21.0m span. The full length between the abutments is 291.57m. The superstructure, overlapping the road from Surgut to Nefteugansk, is steel and split, with orthotropic deck and span’s length 54m. It is suspended with cables on arch pylon in the middle of the deck. The arch tower is steel fixed arch with box cross section.
