Stone Island (Kamenoostrovsky) Bridge across the Malaya Nevka River 9.24.2014

Translated from Russian Wikipedia:
Stone Island Bridge (КАМЕННООСТРОВСКИЙ мост, Kamenoostrovsky) crosses the Malaya Nevku in St. Petersburg to connect Apothecary Island with Stone Island in the alignment Kamennoostrovsky prospect.

In 1760, a pontoon bridge on 11 courts was built by architect AF Vista. In 1765 it was replaced by a new floating bridge with 10 pontoons combined with river abutments on piles. The bridge had to be repeatedly repaired.

Between 1811-1813 the engineer A. Betancourt built the first Russian semiprolёtny wooden arched bridge on wooden poles and stone foundations. Construction was carried out under the guidance of engineers AD Gotman and SO Panteleeva. The total length of the bridge was 150 meters. The bridge lasted 20 years. In 1833, the bridge supports were repaired under the direction of P. Bazin.

In 1859, the project engineer A. Shtukenberg carried out a complete overhaul of the bridge. The arch system was replaced by a complex strut system. In 1875, there was a major overhaul of the bridge for installation of drawn horse railway paths. In 1899, the bridge was completely rebuilt and turned into an 11-flight girder cutting system of four wooden frames with manual transmission. In 1906-1907, the bridge was strengthened to accommodate urban electric railways, under the direction of VR Paw Pomarnacki.

In 1938, Stone Island Bridge has been completely renovated. The wooden girders were replaced by metal I-beams and the hand-drive was electrified. The bridge was 152.5 meters long and 18 meters wide. Work on the repair was led by engineer led PP Stepnov.

In the years between 1953-1954, because of growing traffic intensity and load growth, and given the dilapidated state of the bridge, a new pyatiprolёtny metal bridge with a middle swing span was built by project engineers Lengiproinzhproject VV Demchenko, BB Levin and architects PAAresheva and VSVasilkovskogo. Concrete slabs with asphalt decking was used for the first time on the wings of a draw span, instead of the usual wooden decking. The bridge was simultaneously constructed with the Ushakovsky bridge, whose motto was "invisible draw span". This design decision was so successful that it was used in the reconstruction of Liberty Bridge across the Big Nevka.

The bridge was opened to traffic October 17, 1954. In 1999, the bridge overhauled.

The stationary spans are uncut dvuhprolёtnye metal spans 27.45 + 30.14 m. The cross-section consists of welded main beams with a curved bottom chord. The roadway is reinforced concrete slab with a coating of fine asphalt.

The adjustable span are blocked Diptera spans with a sliding-open system with tightly attachments counterweights. In cross section, they consist of a welded I-shaped cross section of the main beams of variable height. According to the joists and beams of the main wings is a laid concrete slab roadway with a coating of fine asphalt. Tram rails were laid as of the summer of 2009 on the draw span bridge, making current bridge wiring is impossible.

The bridge abutments are monolithic. The foundations are pile on wooden stilts. The foundations front surfaces are faced with granite. All intermediate supports are monolithic inherent high pile raft foundation and faced with granite.

There are welded steel railings on the stationary spans, the granite parapet, and on the draw span. The railings include individual cast iron decorations. There are granite stelae and parapets on the supports and abutments of the bridge railing ends.

Due to the limited loading capacity of the bridge the restricted weight is 25 tons.
