Cable-strayed bridge over the Dudergofsky Canal in Krasnoselsky District of Saint Petersburg was constructed in 1986-1988, under the project of engineer A.A. Sokolov of Lengiproinzhproject and architect Yu. Shindin. UKS-6 of Glavleningradinzhstroy GlavUKS was a customer. The bridge is pedestrian, single-span metal cable one.

The cable bridge is a type of suspension bridge consisting of one or more pylons connected with the roadway by liner steel cables – guys. In contrast to the standard suspension bridges where the roadway is supported by vertical cables fastened to the main bearing cables extended along the entire bridge length; the cables (guys) are connected directly to the pylon.

As for the bridge across the Dudergofsky Canal, its span structure consists of the stiffening beams as a package of four I-beams interconnected by a metal sheet. The stiffening beam is supported by six guys – metal cables. One end of each cable is fastened to the span structure, another end – to the pylon made of reinforced concrete and faced by metal sheet. Pylons fastening points in the span structure and ramps are made of steel. Beside the wires galvanization, paint anticorrosion coating is provided. The pylons are located on the left-bank abutment. Pylons height is 15.5 m.

The bridge abutments are made of monolithic reinforced concrete on pile foundation and faced with granite. The pavement is asphalt concrete on orthotropic slab. The railing of a simple pattern is installed on the bridge. There were no bollards. There are granite stages at the entrance.

Such cable-strayed bridge is the first one in Saint Petersburg.
