Concreting of the section of the span structure of the direct passage of the North-Eastern Chord via Yaroslavskoe Shosse has been completed. The technical customer and general designer of the facility is Mosproekt-3, the company that forms a part of the so named Group of companies.

Concreting of the span was carried out by separate sections, it enabled to finally form the constructive part of the section of the main passage at the place of closing of the left-turn ramp to the Yaroslavskoye Shosse.

“In this section we provided the construction of the prestressed span from the insitu reinforced concrete. This type of the span has optimized performance characteristics and enables to make complex geometry structures. In particular, the structure is plate-ribbed and consists of five transverse ribs of different width. Due to the type of the ramp, the distance between two extreme edges of the ribs is arranged with variables ranging from 3.8 to 11.3 meters. Furthermore, it is planned to strengthen the plate of the traffic way by means of plate ribbing in the transverse direction in a section with a distance between the rib axes of more than 6.8 m. Each rib is reinforced by 7 or 10 high-strength 19-strand ropes, depending on its width,” said Anna Merkulova, CEO of The Group of companies Mosproekt-3.

“Up-to-date design and engineering systems were used to analyse the stress-deformed state of the pre-stress structure in a three-dimensional setting during the design and engineering stage. This provided us with the opportunity to conduct a detailed analysis of the operation of the structure and enabled to design and engineer the span with such complicated geometry,” added Evgeny Astafyev, Deputy Chief Engineer of the company Mosproekt-3.

The North-Eastern Chord is a new highway that is going to connect three districts of the capital in the center of the metropolis. With its launch, the traffic load on the Third Circle Road, outbound routes and the Moscow Circle Automobile Road in the north-eastern area of the city will definitely decrease.
