DVORTSOVY BRIDGE (1918-52 Republican Bridge, in honour of the Soviet Republic), across the Bolshaya Neva, joining Dvortsovy Passage with Birzhevaya (Stock Market) Square. Named after the Winter Palace. The project for a pontoon bridge was developed in about 1828 (engineer P.P. Bazen). From 1856-1912, in this position was St. Isaac’s Bridge. In 1879, experiments were performed with electric traffic lights by P.N. Yablochkov. The permanent Dvortsovy (Palace) Bridge was built in 1912-16 (engineers A.P. Pshenitsky and Colomensky Plants Society). Three competitions took place before the construction, in which 54 designs were entered. Dvortsovy Bridge is a metal, five spans, covered with an unbroken beam framework with curvilinear outline for the lower girdles. The navigation opening is a two wing, two span construction - the first in the world and a successful decision for the locking system of the third articulating arch. The piers are concrete with granite facing, and the bridge has a caisson foundation. In 1939, a cast iron handrail was added (architect L.A. Noskov, sculpture. I.V. Krestovsky), in 1956-57 parapets were added on the piers with red granite. In 1967 and 1977-78, a full overhaul was undertaken. In 1998, the tramline was removed from the bridge. In 2001, the transverse girders of the bridge were repaired and the links of the opening span. Length from alignment with the embankment 260.1 metres, width: 27.7 metres.
