December 18 commissioned plot reconstruction of the federal highway M-7 "Volga" from Moscow through Vladimir, Nizhny Novgorod, Kazan to Ufa km 564 +000 — km 579 +700 in the Nizhny Novgorod region, the Chuvash Republic (2 and 3 start-up facilities).

Acceptance committee reviewed the documentation for the project and inspected the site. Also made additional measurements of the width of the roadbed, curbs, pavement, roadway cross slopes and roadsides, and tests of adhesion of the coating. According to the results of the inspection committee members set their completed works project.

Work on the reconstruction of the next section of the M-7 "Volga" was conducted in the framework of the federal target program "Modernization of transport system of Russia." Work on the site began in November 2010.

The reconstruction is another important part of the M-7 "Volga" with the length of 3.4 km was 1b match the technical category. Instead of the two-lane traffic now organized quad, two lanes in each direction, between which there is the dividing line with the barrier fence. Carriageway width has increased by 2.5 times.

In the course of constructing the road builders used innovative designs and materials. For example, the topsheet is made of paving stone mastic asphalt (SMA-15), which considerably improves the strength of the coating. To enhance the strength of the pavement layers between layers of gravel and sand stacked separating layer of non-woven geotextile "Dornit-2." Gabion structure lean-reinforced (inputs and outputs) of pipes. Another innovation, easy-to-assemble and durable in operation, — the device arch viaduct of corrugated galvanized metal.

The device allowed the two overpasses to separate high-speed traffic flow on the main road from the adjacency of local roads, which greatly increases the level of security of travel site. To ensure the safety of traffic signal poles installed as well, barrier fence, traffic signs. Thermoplastic road marking is made. On the site there is a pedestrian walkway, is organized lighting. The road at the insertion site undeveloped Auto Pavilion and toilets.
