Isaakievsky Bridge

Categories / Architecture/Bridges
ISAAKIEVSKY BRIDGE, (St. Isaac’s Bridge) the first floating bridge over the Bolshaya Neva, opposite what is now Decembrist Square. It linked Admiralteysky Island with Vasilievsky Island. In 1727, the bridge was first launched. From 1732 it was launched annually (in 1856-1912 on the site of the present Dvortsovy Bridge). In 1819-21, it was rebuilt as a pontoon span bridge with strut-supported decks (engineers А.А. Bethencourt, V.K. Traitteur); the rubble abutments were faced with granite and rounded staircases. Isaakievsky Bridge burnt down in April of 1916. As for the bridge range, until 1844 there were approximately 70 projects designed, none of which were carried out - floating and permanent bridge projects, with most interesting designs being those of I.P. Kulibin (three timber, 1769-76, and three metal ones, 1806-15), of P.P. Bazen (two suspension, 1825-27, jointly with G. Lame and B. Clapeyron, three floating bridge projects), of N.I. Bogdanov (with lattice girders), of А. De Fontaine and S.B. Kerbedz (1841, suspension bridge projects).
