SOUTH-EASTERN CHORD INTERCHANGE WITH PROSPEKT MIRA IS GOING TO BE CONSTRUCTED IN 2022

Theconstruction of the North-Western chord interchange with Prospekt Mira is in its final stage, 76% of work has been done. The project of the structure was developed by the engineers of Mosproekt-3, which is one of the three companies consolidated into the Group of companies.

“North-Eastern chord is one of the largest-scale road projects of Moscow throughout its history. It lies from Businovskaya interchange to Nekrasovka, technically from the new road for St Petersburgh to the future road for Kazan. Moreover, the route of the chord is going to pass through 26 districts of Moscow and is going to improve the transport situation in the North-East of Moscow. The construction of the interchange is scheduled to be completed next year,” – Sergei Sobyanin, the Mayor of Moscow.

4,6 kilometres of roads are expected to be constructed within the project of the North-Eastern chord interchange with Prospekt Mira. For the pedestrians’ comfort two underpasses are going to be upgraded.

“Two overpasses of 702 metres and 460 metres length are going to be constructed to provide the traffic on the main road of North-Eastern chord above Prospekt Mira and railway lines of Yaroslavskoye route of Moscow railway. Four other overpasses will provide the ramps from the main road of North-Eastern chord into Yaroslavskoye shosse on the way to the suburbs and from Yaroslavskoye shosse into the North-Eastern chord on the way to the centre. Apart from that, there are certain plans to reconstruct the alternate route of Yaroslavskoye shosse and to extend the side driveways alongside Prospekt Mira, laying the speed change lanes,” – Andrey Bochkarev, the Deputy Mayor of Moscow on Urban planning and construction.

The engineering constructions, designed and engineered within the interchange, cross thrice the Yaroslavskoye suburban railway lines of Moscow railway that is one of the most congested in Moscow. The experts of The Group of companies Mosproekt-3 had to apply unique decisions.

“Our engineers suggested span launching of the main course by means of full cross-section. It was done to minimize the “technological intervals” in the operation of the railway systems, thus relieving the pressure on the railway service. Apart from that, the applied technology enabled to accelerate the process of construction and make it more secure”, – Anna Merkulova, CEO of The Group of companies Mosproekt-3.

The conventional method of launching could not be applied due to the extensive railway infrastructure in that location.

“In this case we had to settle each trestle individually into the space between the railway tracks, that is way they are located non-symmetrically. The span over its entire course is of different width which complicates the process of launching intensely,” – Evgeny Astafiev, Chief Engineer of the Engineering Structures Department of Mosproekt-3.

The engineers of the GC Mosproekt-3 managed to find the solution, having applied the incremental launching on the elastically settled-in trestles. Such a construction tends to compensate the load imbalance on the trestles when displacing the span and enables to keep it in a steady state.

Alexandr Shumilov, the Head of Engineering Structures Department of Mosproekt-3, as an expert, told the television channel “Moscow 24” about the densely development effect on the design and engineering of transport objects.
