History

‘Gerard’ bridge

The first bridge to be built was constructed at the end of the 18th century; construction was supervised by engineer Ivan Gerard. The ‘Gerard’ bridge replaced a wooden beam aqueduct built to carry the Ligovsky Canal—the Yamskoi Vodoprovodniy Aqueduct—though the Ligovsky Canal was filled-in in the 1890s;^{[citation needed]} the ‘Gerard’ bridge occupied the alignment of the filled-in canal.^{[citation needed]}

‘Bazaine’ bridge

After having problems with decay^{[clarification needed]} and levels of passenger traffic, the ‘Gerard’ bridge was replaced. Engineer Pierre-Dominique Bazaine supervised the construction of the second bridge on the current bridge's site, which took place between 1816 and 1821.^{[citation needed]}

‘Erakov’ bridge

A third bridge was constructed between 1846 and 1848 under the direction of engineer A. N. Erakov. The ‘Erakov’ bridge featured granite pools for drinking from,^{[clarification needed by rewording sentence]} with the water being sourced from the Ligovsky Canal.^{[citation needed]} The ‘Erakov’ bridge was repaired and reconstructed in 1862, 1872 and 1874^{[citation needed]}—though changes were not made to the bridge's design or general appearance.

Current (‘Guttsajt’) bridge

With intensive building in southern areas of (the then) Leningrad in the 1950s, Ligovsky Avenue and the roads around Obvodny Canal Quay became congested.^{[citation needed]} The 14 metre-wide ‘Erakov’ bridge—built in 1848—was too narrow to cope with the volume of traffic using it and, thus, a decision was taken^[who?] to substantially widen the bridge.

The current bridge was designed by architect L. A. Noskov^{[citation needed]} and was constructed between 1968 and 1970, developed by engineers N. P. Agapov and A. D. Guttsajt.^{[citation needed]} The ‘Guttsajt’ bridge was substantially wider than its predecessor—at just under 45 metres in width—and was opened to public use on November 7 1970.^{[citation needed]}
