Main route overpass bearings at the South-Eastern Chord section from Grayvoronvskaya to Shosseynaya Street are 50% complete. The facility was designed by Mosproekt-3 JSC, which is a member of the same named holding company.

“Constructors continue preparation for span launching and road bed concreting. To minimize impact on Volgogradsky Avenue automobile traffic (Volgogradsky Avenue is one of the busiest outbound highways), designers decided to apply traverse launching method. That means metal structures will be assembled near the highway and then will be brought into a final position by a jack”, – said Andrey Bochkarev, the Deputy Mayor of Moscow for Urban Planning and Construction.

Because of lack of space and utilities in the site area, The Group of Companies Mosproekt-3 had to develop an individual approach to every overpass bearing within the Chord interchange structure at the intersection with Volgogradsky Avenue.

“Artificial structures have two intersections with the Kursky Suburban Railway Line; they also have intersections with the Big Circle Line tunnels under construction and operating section of the Tagansko-Krasnopresnenskaya Line. In order to reduce noise and vibrational impact, we used bored pile foundation. Diameter of each pile was chosen depending on the specific situation. For example, in some cases we used piles, which are up to 2 m in diameter”, – explained Anna Merkulova, The Group of Companies Mosproekt-3 CEO.

According to Anna Merkulova, this approach allows to decrease the number of piles and make foundation more compact by integrating it into the underground space at high utility density areas.

The section from Grayvoronvskaya to Shosseynaya Street will improve transport service for Pechatniki and Tekstilshiki Disticts, will reduce transport load on the interchange at the intersection of the TTK and Volgogradsky Avenue, and will provide comfortable access to residential development, social and cultural facilities.
