Movement along the entire CRR will be launched in the third quarter of this year

Builders work around the clock at the first launch complex of the Central Ring Road (CRR) at the territory of Larger Moscow.

“Currently, the works on the CRR are almost finalized. The last section of 25 kilometers long will be open this summer, and there are only minor works left. According to our assessments, it is 83% ready. The works on it are perfomed around the clock”, commented Marat Khusnullin.

21 artificial structures are installed along these 25 kilometers. Their readiness ranges from 80 to 95 percent, stated Vyacheslav Petushenko, Chairman of the Board of “Russian Highways” State Company. Base line of mound formation is backfilled, and the lower layer of stone sand mixture is formed, he added. At the same time, road reservations and clearance boxes are arranged, road and information signs are erected, along with metal barriers and noise screens.

Artificial structures are finalized. Crossover of M-2 "Crimea" Highway now has supports, beams, and interjoints are encased. Levelling coat is being arranged, and crossover will be connected with the embankment. Further, the facility will be waterproofed, and asphalt concrete road will be laid.

In addition, a bridge is built over the Petritsa River at the first CRR launch complex. 24 reinforced concrete span beams are already mounted. In total, there will be 36 span beams. When the latter are mounted, road construction workers will connect the crossover with the embankment (install transition slabs and expansion joints), encase the span beams (seams between them will be covered with concrete turning them into a monolith structure), and lay the bridge deck. In late May, it is planned to start asphalt laying on the bridge.

This bridge is peculiar as four out of eight intermediate supports are laid more than three meters below the water surface. Designers opted for land cofferdam. About 300 tons of fillets were unloaded during the works. Modern innovative technologies were applied: barriers and suspended trench drains are made of composites, in line with other CRR launch complexes. Unlike metal, composites are not corrosion-prone, so they do not demand regular repainting.

In general, around 1,300 people and 150 road construction machines are involved at the first CRR launch complex.
