3-rd Transport bridge over Kazanka, Road and tram bridge in Kazan, Russia

The Third Transport Dam, also called Kompressor Bridge, is a hydraulic and transport structure crossing the Kazanka River along Khusain Yamashev Avenue in Kazan. It consists of an embankment dam carrying an asphalt road and tram tracks, plus two parallel bridges over the river channel: a high three-span bridge of precast reinforced concrete and a low five-span bridge of precast concrete.

The bridge was completed in 1976 as a major step to improve traffic connections in the growing city during the Soviet era. Its construction reflects the engineering techniques of the 1970s that allowed Kazan to link its districts more effectively.

Locals call it the Compressor Bridge after the nearby Compressor factory, and trolleybus routes 2 and 13 plus tram routes 5, 5a and 6 run across it. It links the bedroom district of Novo-Savinovo with the Siberian Trakt and the road to the M7 highway. Traffic accidents here can paralyse movement, causing long jams on Yamashova Avenue and Academic Arbuzov Street.

The dam carries buses, trolleybus routes 2 and 13, and tram routes 5, 5a and 6, so expect heavy traffic on Prospekt Khusaina Yamasheva and Akademika Arbuzova. Accidents here can paralyse movement and cause long jams, so allow extra time. A low parallel bridge north of the main span was kept as a reserve and is intended for future metro use.

During construction the tram rails were embedded directly in reinforced concrete, which later made replacing them difficult. A temporary duplicate bridge built north of the main span after 1994 still stands, and the old bridge was preserved rather than demolished after repairs ended in 1999.
