The M10 "Russia" () 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 road,  long, in this area was built by order of Peter the Great from 1712 to 1746.

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.
