Krasnooktyabrsky Bridge across the Bypass Canal 9.22.2014

Translated from Russian Wikipedia:
Krasnooktyabrsky bridge (Краснооктябрьский мост) crosses the Bypass channel in the alignment of Rosenstein street in St. Petersburg.

The first bridge on this site was built in 1914. It was a wooden trapezoidal-braced bridge trehprolёtny design. The bridge was called Leuchtenberg, because of nearby Leuchtenberg street. In 1925 the dilapidated bridge was dismantled.

Between 1957-1958 a reinforced concrete bridge named Krasnooktyabr'skaya was built. for the purpose of expanding heating pipes across the canal. Originally it was only supposed to be a pedestrian bridge but it was giving a transport function the second phase of construction.

The bridge was designed by the "Lengiproinzhproject" institute. The author of the project was engineer V. Blazevic.

The bridge is a monolithic reinforced concrete structure, according to the static scheme - two-hinged frame. The full length of the bridge is 32.44 m and the full width is 18.80 m. The roadway clearance is 12.00 m. The sidewalks are 2 × 3,20 m.

It is a monolithic bolt frame ribbed design, with a calculated span of 23.48 m. Within the bolt cross section are nine main beams. There are an average seven beams combining the carriageway slab thickness of 14 cm and four apertures. The main beams bolts have curved shapes of the lower zone by changing the height of the center crossbar height of the beams (which is 93 cm, at the junction with the foot frame 148 cm). The bearing on the foundations is through lead joints.

The concrete bridge supports are monolithic. The base of the foundation pillars are wooden piles. The foundations and lean-faced pink granite facade are painted beams. Asphalt covers the roadway and sidewalks. Reinforced concrete embankments are installed on the bridge. The railing are cast iron grilles, fixed on metal pedestals. The extreme section of railing are embedded in the granite parapet foundations. Decorative metal poles are installed on the bridge foundations which feature lighting fixtures.
