# M10 highway (Russia)

The M10 "Russia" (Russian: "Россия") is a federal highway in Russia connecting the country's two largest cities, Moscow and Saint Petersburg. Other than in the vicinity of Moscow and Saint Petersburg, the M10 is basically a two-lane highway (one lane for each direction), with an occasional third centre lane to allow overtaking or for left-turning traffic at intersections.

## History

The highway Moscow - Tver - Novgorod existed even before the founding of Saint Petersburg. Along the way there were special checkpoints (Yam) in particular Yedrovo, Valday, Yazhelbitsy, Krestsy, and Bronnitsa. The first 778 kilometres (483 mi) long road in this area was built between 1712 and 1746, by order of Peter the Great.
The construction of this road was run by an office that formed for this purpose. After the completion of the road in 1755, it was transformed into the Office of the structure of public roads. It was later known as the Commission on the Roads in the State.

The route section between Saint Petersburg, and the border with Finland is known as the "Scandinavia" (Russian: Скандинавия) highway and has officially been renamed to route A181. The designation M10 stayed valid until December 2017. This section is a part of the European route E18. News about the plans to expand this route section to a motorway with three lanes in each direction came out in August 2011.

### Characteristics

The temperature range is almost unchanged: the annual average temperature throughout the section of the road may vary between 2 and 4 °C. The average temperature in January is -11 °C. In July it is +19 °C.
The road crosses the river Sister (a tributary of the Dubna, near Klin), Volga (in Tver), Msta (near Novoselitsy), Volkhov (at Krechevitsy), etc. Bridges longer than 50 meters have a capacity of 60–80 tons. In Tver region (127 km, 132 miles), there are bridges with carrying capacity of 40 tons.
