THE SPAN OF THE OVERPASS OF THE NORTH-EASTERN CHORD THROUGH YAROSLAVSKOE HIGHWAY HAS BEEN COMPLETED

Concreting of the section of the flyover structure of the direct passage of the North-Eastern Chord via Yaroslavskoe Highway has been completed. The technical customer and general designer of the facility is Mosproekt-3 JSC, which is part of the same name holding.

Concreting of the superstructure was carried out by separate sections, it made possible to finally form the constructive part of the section of the main passage at the place of closing of the left-turn exit on the Yaroslavskoe Highway.

“We have planned to erect a prestressed monolithic reinforced concrete superstructure at this section. This type of superstructures have optimum performance characteristics and make it possible to make complex geometry constructions. In particular, the structure is plate-ribbed and consists of five different width transverse ribs. Due to the exit, 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 carriageway 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,” Anna Merkulova, The Group of Companies Mosproekt-3 CEO, said.

“Modern design systems were used to analyse the stress-deformed state of the pre-stress structure in a three-dimensional setting during the design stage. This made it possible to conduct a detailed analysis of the operation of the structure and allowed us to design such a complicated geometry superstructure,” Evgeniy Astafyev, Mosproekt-3 Company Deputy Chief Engineer, added.

The North-Eastern Chord is a new highway that will connect three districts of the capital in the center of the metropolis. After its launch, the traffic load on the Third Ring Road, outbound routes and the Moscow Ring Road in the northeastern area of the city will decrease.
