Kamennoostrovsky Bridge spans the Little Nevka River and connects Aptekarsky Island with Kamenny Island in Saint Petersburg, Russia. Originally constructed as a floating pontoon bridge in 1760. Between 1811 and 1813, Kamennoostrovsky Bridge became the first seven span timber arch bridge in Russia. In 1859, the bridge was improved with the addition of strut-supported spans. In 1952, the bridge was rebuilt to its current design with five spans.[1]
The bridge was originally designed by architect Alexander Vist in 1760 to be a pontoon bridge consisting of 11 pontoon sections. In 1765, the pontoons were replaced with a floating bridge and was connected to the river abutments on piles.[1]
19th century improvements
Between 1811 and 1813, Project Engineer Agustín de Betancourt replaced the floating bridge with a seven span wooden arch bridge on timber foundations with stone abutments. The total length of the bridge in this form was 150 metres (492.1 ft).[1]
In 1859, Project Engineer Anton Shtukenberg conducted a complete reconstruction of the bridge. The arch design was replaced with a complex strut-frame system.[1]
In 1899, during repair work, the bridge was completely rebuilt again. This reconstruction converted the bridge from a seven span to an eleven span simple timber bridge.[1]
