Ob River Crossing – Bugrinsky Bridge in Novosibirsk

Ob River Crossing – Bugrinsky Bridge in Novosibirsk

Novosibirsk (new construction)
Design, Detail Design Development
Project period: 2008 – 2014
General Designer: Institute Stroyproekt AO
Contractor: Sibmost ZAO
Client: Mayor’s office of Novosibirsk, Road Construction Administration


The new bridge, construction is completed, (the 3rd one) across the Ob River in Novosibirsk is located at the alignment of Olovozavodskaya Street and includes traffic interchanges: in Vatutin, Bolshevistskaya and Kirov Streets.

Main technical parameters:
 – total length of the bridge with approaches: 2,091 m
 – central span: 380 m
 – lanes: 3+3
 – navigation span dimensions: 160 х 15 m
 – two traffic interchanges with overpasses of 69 and 318 m long
 – traffic capacity of the river crossing: 7,180 vehicles per hour (with design speed of 80 km/h).

The central span has a combined deck: a tied arch with inclined suspenders (so called “network arch”). The central span is 380 m long, which is unique for Russia (as well as for Europe and Asia). Visually, the 70-m high arch resembles a gigantic red bow that is one of the Siberian symbols represented in the coat of arms of Novosibirsk.

The bridge does not only relieve significantly traffic flows in Novosibirsk but also ensure uninterrupted traffic between motorways M-51 “Baikal” and M-52 “Chuisky Trakt”.

The engineering and design effort resulted in a solution with a 380-m long network arch that is unique in terms of its dimensions and erection method. In Russia, the largest similar arches with flexible suspenders were 160 m long as a maximum.

The river span of the bridge is a combined arch deck with inclined crisscross suspenders (so called network arch): the arch is 70 m high and the arch legs are inclined inwards by about 12o towards the longitudinal axis of the deck.

The designers managed to find a solution that met the following criteria:


 Reduced steel consumption for the arch and the bottom flange due to decreased bending moments;
 Reduced effect of live loads on cables tension;
 Reduced material consumption for cables due to their optimised cross-sections;
 Reduced maximum forces in cables and their cross-sections;
 Decreased stress variation amplitude and reduced risk of fatigue failure;
 Aesthetically pleasing bridge appearance

The designers managed to find the best solution for the cable system arrangement, which allowed achieving an extremely efficient design of the deck system enabling reduced steel consumption and ensuring a high rigidity of the structure.

Based on the proposed engineering solution, the architects developed an aesthetic concept of the bridge. Despite the considerable dimensions of the deck, the arch span is a light and visually pleasing structure. Moreover, the arch looks like a hunting bow which has a symbolic meaning in relation to the Siberian history.
