This is the earliest bridge built in St Petersburg. In the 18th century it was known as Petrovsky. Shown on the city map of 1705, it had been constructed two years before, first as a floating one. In 1706 it was put up on wooden piles and became a drawbridge. Located next to the bridge, in Troitskaya Square, was Peter I’s notorious Austeria (tavern). In 1738 the bridge was completely rebuilt and arched stone supports were added to it by the Kronverksky Strait banks. These supports carried the wooden structure with piles while its central span had a bascule. The bridge has remained almost the same since then. In the 1950s in the cause of its restoration undertaken to mark the 250th anniversary of the city its wooden elements were replaced with metal ones and it was decorated with metal railings and lampposts modelled on the railings and lamps of the floating Troitsky Bridge (engineer P. Stepanov, architects N. Belekhov and A. Rogach). The bridge is 74.66 m long and 10.51 m wide.
