Kantemirovsky Bridge
Kantemirovsky most
The Kantemirovsky Bridge is the last drawbridge to be built.
This is a 17-span structure with a draw span in the middle, and only five spans with a total length of 198 m are located above the river (two of them are within the supports of the draw span). Two spans pass over the embankments and ten (in the form of two overpasses) are hidden in ramps. Thanks to the approach ramps, the Kantemirovsky Bridge is the second longest draw bridge in the city, second only to the Alexander Nevsky Bridge.
The draw span is a single-wing opening system with a fixed axis of rotation, with rigidly attached counterweights. The clear size of the draw span is 43 meters. The span structure in cross section consists of four welded main beams. The bridge is raised by means of a hydraulic drive. The control panel is located in the left-bank support of the draw span. The draw span is carried out upon request, submitted two days in advance.
The permanent spans are covered with two-span continuous prestressed metal beams of variable height. In the cross-section, the I-beams are connected by transverse beams and an orthotropic slab.
The intermediate supports are lightweight reinforced concrete on a pile foundation, faced with granite. The supports of the overpass section are lightweight reinforced concrete on a pile foundation without facing.
The railing is made according to the Tuchkov Bridge type. It consists of square-section metal rods that create an unusual volumetric picture that has not been seen before in bridge construction practice. The author of the lattice is the architect P.A. Areshev.
At the entrance, massive rectangular pedestals are installed, along the upper edge of which a metal strip-board with the name of the bridge is placed. Granite stairways with a granite parapet are built on four sides of the abutments.
