Novosibirsk metro bridge, Metro bridge across Ob River in Novosibirsk, Russia

The Novosibirsk Metro Bridge is a seven-span covered metro crossing over the Ob, 2,145 m long (896 m over the river), linking Sportivnaya and Rechnoy Vokzal stations on the Leninskaya Line. Its right-bank and left-bank galleries are glazed turquoise box corridors with 2 m by 2 m windows; the central span is a grey reinforced-concrete box with porthole windows, half closed since the mid-1990s. The bridge rests on V-shaped reinforced-concrete piers.

The final design came from Lengiprotransmost in 1978, by chief engineer K. Vinogradov and architect S. Tsyganov: a separate crossing on 14 piers, 80 m south of the Oktyabrsky bridge, after tunnel and shared-deck options were rejected. Work began in August 1980 with the river piers, finished in December 1982; the span was launched by hydraulic jacks and set on the piers by 31 January 1985. On the night of 19 December 1985 four loaded trains of sand bags, 1300 t in all, tested the bridge; trains began running on 7 January 1986.

The bridge's name, metromost, is the everyday Russian term for a metro bridge, and its two portal galleries are glazed turquoise boxes with 2 by 2 metre windows. Since the mid-1990s the porthole windows of the grey central span have been half closed. The station Sportivnaya sits on the left-bank gallery, parallel to the Kommunalny Bridge dam.

The bridge carries only metro trains of the Leninskaya Line between Sportivnaya and Rechnoy Vokzal; there is no road traffic. Sportivnaya station sits on the left-bank gallery, parallel to the Kommunalny Bridge dam. From the mid-1990s the porthole windows of the central span have been half closed, so views from passing trains are partial.

The bridge features a fully enclosed design that shields trains and passengers from harsh Siberian winters. This protective covering makes it a rare example globally and keeps snow and ice from disrupting daily operations.
