The Novosibirsk Metro Bridge ( Russian: Новосибирский метромост ) in the Russian city of Novosibirsk runs the double-track Leninskaya Line (Ленинская) of the Novosibirsk Metro over the Ob .
It stands about 60 m upriver from the Oktyabrsky Bridge (municipal bridge), which bears the name of the district .
The total of 2145 m long bridge structure begins in the partially above-ground station Retschnoi Voksal (Речно́й вокза́л) on the eastern bank, leads with a 154 m long bridge over the six-lane Bolshevistskaya ul. To a large pillar serving as an abutment on the right bank the 896 m long main bridge over the Ob to the corresponding pillar on the left bank and leads with another 1095 m long foreland bridge over the floodplain to the slope with the entrance to the tunnel to Studentscheskaja station (Студе́нческая) .
The main bridge is a steel box girder , the floor of which consists essentially of two solid wall girders in the longitudinal direction and an orthotropic plate . The box girder is fully closed to prevent the trains, which have cooled down outside, from misting up in the warmer tunnels in winter and also to prevent the cold and hot air in the summer from entering the subway tunnels. The originally existing row of smaller round holes was soon closed because the drivers complained about the glare . The box girder rests on the two large bank pillars and on six V-shaped river pillars made of reinforced concrete with pillar axis spacings of 128 m each, which correspond to those of the neighboring municipal bridge . While this still required massive pillars due to the ice drift , the metro bridge built after the hydroelectric power station on the Ob was able to manage with slender pillars. The temperature-related change in length of the box girder can be up to 70 cm, which required special bearings and transition structures. The box girder was installed on the bank and, in sections, pushed across the river using the incremental launching method .
The high bridge on the right bank is a pre-stressed concrete - girder bridge m with four fields, each with 33 to station Retschnoi Woksal extends. It is closed with a roof and side walls made of trapezoidal sheets , although the side walls have windows that can be folded down at regular intervals.
The foreland bridge over the floodplain has 32 fields, also made of prestressed concrete with a roof and side walls made of trapezoidal sheet metal.
Construction of the bridge began in February 1980. In December 1985 the load tests were carried out. Subway traffic across the bridge began on January 7, 1986.
