Dvortsovy Bridge (Palace bridge) is a bascule bridge spanning the Neva River in St Petersburg between Palace Square and Vasilievsky Island. The total length of Palace Bridge is 260,1 meters, width - 27,8 meters. It is actually composed of five spans.

After Emperor Nicholas I lifted Peter the Great's prohibition to construct bridges across the Neva, a temporary pontoon bridge was set up about 50 meters downstream from the current structure. In 1901 the authorities announced architectural competition. 54 proposed designs were rejected and the final project was chosen only in 1911. The design was subject to prevent the bridge from obstructing the view from Palace Embankment towards Kunstkammer, Imperial Academy of Arts, and other structures on Vasilievsky Island. Construction of the cast-iron bridge was started in 1912 to designs by Andrey Pshenitsky, but the work was delayed by World War I and the bridge was not opened to the public until December 23, 1916. In 1918 the bridge was renamed Republican Bridge, but the original name was restored in 1944. In 1936 wood barriers of the bridge were changed to the cast-iron ones, designed by L.A.Noskov. The rest of wood barriers was removed only in 1977.
