Bridge data

Penkovy Bridge is located in Kronstadt on Petrovskaya Street, and spans the Obvodny Canal (Kronstadt).

This is a single-span metal simple bridge.

The span structure consists of eight welded I-beams connected by orthotropic roadway slab with longitudinal ribs and transverse I-beams. The outline of a new span structure is similar to the outline of beams of a pre-existing bridge. The upper zone is outlined by the curve, and the bottom chord is a straightline.

The protective layer made of hydraulic concrete with a metal grid and a cast-iron stone block cover are laid on metal plate. The cells of the stone blocks are filled with fine-grained asphalt concrete.

The bridge abutments are made of rubble concrete masonry with hinged granite facing, which is a continuation of the granite walls of the embankment. The base of the abutments - granite slabs on timber sills. To join the abutments with filling, reinforced concrete approach slabs were used.

The metal railings are installed on the bridge. There is street lighting on the bridge.

Bridge history

The bridge was built in 1873, and rebuilt in 1887-1888. Drawbridges across the Obvodny Canal, that Penkovy Bridge was originally, allowed sailing ships with tall masts on the canal.

The project of major repair of Penkovy bridge as a result of which it has got a modern appearance, was drawn up by the Lengiproinzhproject Institute (Chief Designer – B.E. Dworkin) and the bridge was built in 1971-1972.

In accordance with architectural and restoration work specification the roadway pavement of cast iron blocks was saved on the bridge. This coating was used for the roadway pavement in Kronstadt in the initial period of their construction.

Currently the pavement of almost all the bridges was replaced by a modern type of covering – asphalt concrete, granite slabs.
