Superstructure of Bannoye Lake Bridge installed

Stroytransgaz has completed to install the 80m long superstructure of the Frunzensky bridge across Lake Bannoye. This construction is made of in-situ reinforced concrete, and it used 1,600 cubic meters of concrete.

The superstructure is supported by seven piers, out of which two are on the banks and five are in the lake. To construct the piers, about 1,800 cubic meters of concrete was needed, the construction materials were delivered by local suppliers.

«We have completed major concreting operations on the Bannoye Lake Bridge as scheduled. For this, we used 3,400 cubic meters of concrete. Currently, the surface of the bridge deck is being prepared for installation of waterproofing. Then, we are going to install the road pavement and auxiliary facilities: lighting poles, pedestrian and metal W-beam guardrails will be mounted. In future, this bridge will carry the main traverse of the highway towards the interchange at Shosseynaya street,» said Project Execution Director Konstantin Agalakov.

Meanwhile, piers of the Samara River bridge are still being installed. There will be eight of them—four in the riverbed, and another four on the banks. To date, three abutments are compete—Nos 7 and 8 on the left bank, and No. 2 on the right one.

At the main traverse section between the Samara River Bridge and the Bannoye Lake Bridge, sand is deposited using the hydraulic fill method to build up the roadbed. Filling of working platforms at eight ramps (C1 to C8) is underway in the area of the designed interchange at Shosseynaya St. Also, RC prismatic driven piles are being sunk to construct piers for the overpass at C3 ramp.
