LOWER SWING BRIDGE
The Lower Lebyazhy Bridge was built across the Lebyazhy Canal at the point where it flows into the Moika River.
In 1720-1733. there was a wooden drawbridge built according to the design of the engineer Hermann van Boles. The bridge was called the 1st Tsaritsyn Bridge after the nearby Tsaritsyn Meadow (Field of Mars). By the 1760s. the bridge gave way to a new girder crossing.
In 1835-1837, during the redevelopment of the territory near the Mikhailovsky Castle, a bridge was erected at the place of the crossing, designed by engineers P.P. Bazen, A.D. Gotman and A.I. Remezov. The single-span stone arched bridge with granite-faced facades and supports was named the Lower Lebyazhy Bridge. In 1849 the bridge was repaired due to the settlement of the vault.
In 1925-1926. the bridge was reconstructed according to the project of engineers B.D. Vasiliev and A.L. Salarev. The brick superstructure was dismantled and a monolithic reinforced concrete vault faced with granite was erected instead. At the same time, the appearance of the bridge was preserved.
The last restoration of the bridge was carried out in 2002. The bridge is 23.9 m long and 19.9 m wide.
