OREANDA-NEWS. Mostotrest won the public tender for the right to enter into a long-term investment agreement for the construction, maintenance, repair, overhaul and toll-based operation of the fourth section (km 208 - km 258) of the M-11 "Moscow - St. Petersburg" Highway in the Tver region (Phase 1 construction). Mostotrest has been awarded the contract following the comparative assessment of bidder applications and competences.

The State Company Russian Highways announced the tender for the long-term investment agreement on September 11, 2014. In accordance with the contract, the total cost of construction to be completed in 36 months as of the contract date will be RUB32.3 billion (including VAT). The contract validity period is 23 years, until December 31, 2037. The project envisions contractor investment of RUB5.2 billion (including VAT), in respective year prices. The total amount of payments for maintenance, repair and overhaul during the operational phase will be RUB9.19 billion.

As part of the project, Mostotrest will build a new Class 1A road. Three split-level interchanges and 26 elevated structures, including 4 bridges, 19 overpasses on M-11, 2 overpasses as part of traffic interchanges, and an overpass on the Mednoye-Kulitskoye-Kievo road will be erected on the 47.9 km contracted highway section. The design speed of the new four-lane section is 150 km/h. The new road will run through the Tver region, bypassing the city of Torzhok in the Kalinin and Torzhok districts.

The road will be built as part of the M-11 "Moscow - St. Petersburg" Highway construction project. The km 208 - km 258 section will be part of modern and efficient high-speed automobile road infrastructure linking Moscow with St. Petersburg. The new road will redirect transit traffic currently passing through the streets of Vishny Volochek and 52 other communities, and create conditions for economic growth in nearby regions.

In accordance with current construction requirements, the project envisions all necessary measures to minimize environmental impact, including noise screens, modern local storm water treatment facilities to protect the aquatic environment from pollution, special structures to ensure animal migration routes, and other environmental measures.

Mostotrest will use innovative construction technologies and materials to ensure a high level of quality and durability of infrastructure, as well as to optimize operating costs over the life cycle of the new route. To ensure traffic safety, enhanced barrier protection and durable composite polymeric railing will be installed on bridges and overpasses. In addition, the road section will be equipped with an automated deicing system to prevent winter slipperiness on traffic interchange sections with unilateral cross slopes. The use of advanced materials, structures and technologies to improve water resistance of concrete, as well as durable anti-corrosion coating systems for bridge steel structures will increase maintenance-free service life of the road pavement to 15-25 years.
