The wooden bridge was replaced with a stone one in the 1830s, but the speed of its construction led to significant problems, with the vaulting in danger of collapse.
Numerous repairs and renovations have taken place over the bridge's existence, before finally being given a degree of stability after work in the 1920s, which retained the original appearance.
Today the bridge links the Field of Mars with the Summer Garden at the Swan Canal's junction with the Moyka, close to the Mikhailovsky Castle.
The Lower Swan Bridge is in Dvortsovy Municipal Okrug, part of the Tsentralny District of the city.
[1] The point at which the Swan Canal diverged from the Moyka River was first crossed by a wooden drawbridge built to the design of engineer Harmen van Bol'es, and in existence between 1720 and 1733.
[2][3] The wooden crossing was replaced with a stone and brick one over six months between December 1836 and mid-1837, as part of the redevelopment of the area around the Mikhailovsky Castle.
The structure was strengthened with reinforced concrete and lined with granite, retaining the earlier appearance of the bridge, including Rossi's railings, which were restored.
