The first elements of metalwork of the superstructure on the cable-stayed bridge across the Oka River were delivered to the project site. The average weight of one element used to assemble the mounting units is 13 tons, while its length amounts to 15 meters. It requires 364 such elements to build a bridge crossing 1,377.6 m long, which will connect the shores of Vladimir and Nizhny Novgorod Regions.
As part of preparation for building the bridge over the Oka River, the last phase of engineering and geological surveys is almost completed at stage 4 of the M-12 Highway in the river bed where the foundations of the bridge crossing pylons will be erected.
The drilling unit drove up to the site in the river bed through a special technological bridge. This temporary artificial structure will serve to organize the work for building a pier and installing the main parts of the superstructure in the water area, connecting the right bank and the pier. The working bridge is 80 percent ready; an additional process platform envisaged by the project remains to be built using the floating rig. After the cable-stayed bridge is built, the temporary one will be dismantled.
The bridge across the Oka River is the only cable-stayed bridge on the M-12. The two-pylon bridge construction involves separate supports to be raised, each about 80 m high.
