Deputy Prime Minister of the Russian Federation Marat Khusnullin visited the construction site and assessed the work progress
Deputy Prime Minister of the Russian Federation Marat Khusnullin assessed the construction progress on the bridge across the Oka River on the M-12 Moscow – Nizhny Novgorod – Kazan Highway. The bridge is being built by Bamtonnelstroy-Bridge Group of Companies.
On June 13, the first stage of the superstructure launching began, Marat Khusnullin visited the construction site when the launching process started. Within the first stage 10 meters were launched. Until September 2022, 9 stages of bridge launching are scheduled – 211 meters will be launched in total.
Three methods of superstructure installation are used to build the bridge across the Oka River: longitudinal launching method, installation on temporary piers for the ramp section and cantilever erection for the superstructure over the riverbed.
“We got down to an important stage of the bridge construction over the Oka River. Launching of the superstructure 4-6 from the building berth No.1 has began,” Project Manager of SK MOST JSC (a part of Bamtonnelstroy-Most Group of Companies) Alexander Dmitrishin said.
Besides, he pointed out that the specialists of Bamtonnelstroy-Most Group of Companies apply the continuous concreting technology by using a “sliding formwork” to reduce the construction time when erecting the pylons.
The bridge across the Oka is the only cable-stayed bridge on the M-12 Moscow – Nizhny Novgorod – Kazan Highway under construction. It will connect the Vladimir Region and Nizhny Novgorod Region near the city of Murom. The bridge will be 1,377.6 long. Seventeen reinforced concrete supports on pile foundations including two pylons up to 90 meters high will serve as the supporting structures of the bridge crossing. The bridge has a steel-reinforced concrete superstructure with a 254-meter- long cable-stayed section. 6,800 tons of metal structures, 28,000 reinforced concrete structures will be used for the construction. At the moment, over 1,100 people and more than 120 equipment units are involved in the construction.
