The South-Eastern Chord

In the conditions of an acute shortage of street and road network, The Chord Ring of Moscow is designed to provide Moscow with high-speed cross-links in the middle part of the metropolis. The South-Eastern Chord will reduce traffic load on the busiest roads and in the future will be extended to New Moscow.

Engineering solutions made by The Group of Companies Mosproekt-3 specialists on the sections of the South-Eastern Chord provide the residents of Pechatniki and Biryulyovo Zapadnoye District with the new alternative routes. Before these districts had a poor transport accessibility and were divided by numerous natural and artificial barriers.

On the section from Grayvoronovskaya to Shosseynaya Street, the engineering structures cross twice The Kursky Suburban Railway Line and the Big Circle Line tunnels under construction, as well as the operating sections of the Tagansko-Krasnopresnenskaya Line. In order to reduce the noise and vibrational impact, we used foundations with auger cast piles. Furthermore, the diameter of each pile was selected individually in each specific situation. For example, in particularly cramped conditions we used piles up to 2 meters in diameter.

In order to optimize the construction of the South-Eastern Chord section from the Paveletsky Suburban Railway Line to Moscow Automobile Ring Road (MKAD), our specialists applied different approaches to different parts of the engineering structures. On the sections, where we didn’t have to deal with the issues connected with topography or existing development, we used reinforced concrete prestressed beams for a span construction. For spans that cover railway lines, we used metal structures and orthotropic deck. The third section has a complex geometry, so we chose reinforced concrete ribbed plates due to the span’s location, as it is located both at entrance and exit roads of the South-Eastern Chord main road.
