Palace Bridge, a road- and foot-traffic bascule bridge, spans the Neva River in Saint Petersburg between Palace Square and Vasilievsky Island. Like every other Neva bridge, it is drawn by night, making foot travel between various parts of the city virtually impossible. The bascule span was designed by an American firm, the Scherzer Rolling Lift Bridge Company, and built by the French firm Société de Construction des Batignolles between 1912 and 1916.
The total length of Palace Bridge is 260.1 metres, width is 27.8 metres. It is actually composed of five spans, the southernmost joining Palace Embankment between the Winter Palace and the Admiralty and leading to Palace Square.
