Kronstadt, located on the water, is famous for its many bridges, most of which were built during the Russian Empire. Among them stands out the Penkovy Bridge, originally erected in 1873 and reconstructed in 1887-1888. This drawbridge spanned the Obvodny Canal, allowing sailing ships with tall masts to pass through.

The bridge maintained its pre-revolutionary appearance for almost 100 years until major repairs began in the 1970s, completed in 1972. Last year, the bridge underwent repairs again, during which about five thousand cast iron slabs were laid on its surface, five hundred of which were made during the Russian Empire. Unlike most other bridges in the city, which have long been asphalted, this bridge has preserved its unique surface.

The bridge's structure includes a span made of eight welded I-beams, combined with an orthotropic slab of the roadway with longitudinal ribs and transverse I-beams. The new span replicates the outlines of the previous beams: the upper flange is curved, while the lower one is straight. On the metal plate, a protective layer of hydraulic concrete with a metal mesh and cast iron slabs is laid, the voids of which are filled with fine-grained asphalt concrete. The bridge's supports are made of rubble-concrete masonry with granite cladding, continuing the granite walls of the embankment. At the base of the supports lie granite slabs on wooden sleepers, and reinforced concrete transition slabs are used to connect the supports with the embankment. The bridge is also equipped with metal railings.
