Large Izhorsky Bridge

The Big Izhorsky Bridge is a seven-span reinforced concrete girder continuous bridge in Kolpino on Proletarskaya Street, built from January 1975 to October 1977 by the efforts of SU-2 of the "Lenmostostroy" trust under the leadership of chief engineer L. S. Kulibanov. The construction involved the brigades of I. A. Pyzhov, A. P. Lebedev, E. F. Trus, and A. I. Galoshin, and thanks to the chairman of the Kolpinsky District Executive Committee, A. P. Paranichev, the project was implemented without the use of earthen dams. Each channel support of the bridge consists of two independent semi-supports with rocker-type bearing parts, and its span structure is formed by 12 I-beams. The roadway and sidewalks of the bridge have an asphalt concrete surface.
