Irinovsky Bridge across the Okhta River (with the Bypass Bridge in the background) 9.27.2014

Translated from opeterburge.ru:
The Irinovsky Bridge (Ириновский мост) crosses the Okhta River along the axis of Irinovskaya Avenue. It is a three-span reinforced concrete beam construction, in a continuous system. It was built here between 1982-1983 by project engineer AA Sokolov. There was an earlier Irininskaya bridge, known as the 1st Okhta Bridge (now Bypass bridge) located upstream, which provided tram connections to the Rzhevsk tram line.

The name Irininskaya comes from the Irinovka village, which was situated near St. Petersburg, on territory used to harvest peat in the 19th century. Modern Irinovsky Avenue additionally got its name from the former Irinovskaya railroad where it now runs. The Irinovskaya railroad was laid in 1889, when Baron Paul Leopoldovich Korf, who served as Mayor and Chairman of the Free Economic Society, wished to build a railway line from the Neva River to his Irinovka estate. This project was approved by the Emperor Alexander III, and became the first Russian railway. The new railway line become very popular among the residents along the Ohta River. A new road, which later became the current Irinovskaya prospectus, was eventually built along the railway line.

The modern Irinovsky bridge is a reinforced concrete structure. The superstructure consists of reinforced concrete beams in T-section with parallel belts. The facade of the bridge is decorated with a lining of metal sheets with a system of decorative belts. The foundations are made of concrete monoliths, standing on concrete stilts. The piers are lined with granite and are composed of five racks mounted on a common pile raft foundation. The steel railing is a simple design. There are lamps placed on metal supports. The total length of the bridge is 63.3 meters and its width is 55.5 meters.
