OREANDA-NEWS. Mostotrest specialists have completed the construction of the Vyshny Volochyok Bypass in the Tver region - the 5th construction phase of the new Moscow-St.Petersburg Highway (M-11) (km 258 - km 334) - seven months ahead of schedule. The construction projects was completed by Transstroymekhanizatsiya LLC, which is part of Mostotrest Group, at the order of the State Company Avtodor.

The Vyshny Volochyok Bypass became the first commissioned section of the toll road Moscow - St.Petersburg Highway (M-11). In accordance with contract terms, Mostotrest will provide maintenance, repair and operation of the site and automated traffic management systems for 18 years after the completion of the construction phase. The section will be operating in toll-free test mode until july, 2015.

The Vyshny Volochyok Bypass is a new, modern roadway with lighting that is constructed in accordance with the highest international standards. The construction project for the 72 km stretch includes 54 elevated structures, including 40 flyovers, 14 bridges and 2 split-level interchanges (intersection with the M-10 Highway at km 257+474 near the village of Budovo, and at km 329+947 near the village of Kurskoye). The Vyshny Volochyok Bypass has 4 lanes (two in each direction) with the design speed of up to 150 km/h, and 4 rest areas with the capacity of up to 29 vehicles each.

The Mostotrest Group and TSM have significantly reduced the time of construction through the use of modern technologies and an efficient project management system. Many types of machinery and specialized equipment used to build the new 72-kilometer stretch of the road are among the most advanced technical solutions in the field of construction. Specifically, productivity has been boosted several times by equipping vehicles and machinery (graders, pavers, bulldozers, etc.) with 3D-navigators that accurately reproduce the design parameters of the road and guide construction vehicles and machinery accordingly.

Innovative technologies increasing the life and reliability of infrastructure and minimizing impact on the environment have been used during construction of the road and its elevated structures.

To clean storm and snow wastewater, high-capacity multi-stage treatment plants (including a two-stage sorption filter) have been erected. Purified water thus meets all the stringent standards for water discharged into fishing reservoirs.

Gabion structures for slope stabilization allow to preserve the local ecosystem in the construction area and support landscaping and drainage. During construction, slopes were additionally reinforced with spraying a fertilizer and plant seed mix. The plants' root system creates an additional protection of soil from erosion.

Barrier fencing to prevent access of wild animals to the roadway and underpasses for animals have been built along the road stretch.

The roadway and traffic interchanges are equipped with LED lights lowering energy consumption by 2 and allowing the use of lighting without damage to the environment.

The 72-kilometer Vyshny Volochyok Bypass (km 258 - km 334) is part of the M-11 Highway, under construction in accordance with the contract from the State Company Avtodor. The road segment passes through the Torzhokskiy, Spirovskiy and Vyshnevolotskiy districts of the Tver region.

Currently, Mostotrest is also completing the construction of the head section (km 15 - km 58), continues to work on the construction of the sixth section (km 334 - km 543) of the Moscow-St.Petersburg Highway (M-11), and will also implement a project for the construction, maintenance, repair, overhaul and operation of the fourth phase on the km 208 - 258 km section of the M-11 highway in the Tver region at a fee (first construction phase).
