Malyshev Street. One of the oldest streets in Yekaterinburg. Previously, the street was called Pokrovsky Prospekt. In 1919, the street was renamed in honor of Ivan Malyshev, since it was here in the house number 46 in 1917 that the Yekaterinburg Committee of Bolsheviks was located, which immediately after leaving the underground was headed by I. M. Malyshev, who was killed by the white guards in 1918.

In 1763, the Tobolsk road became the Siberian highway, and the part of the highway passing through Yekaterinburg became known as Sibirsky Prospekt. In 1935, the Avenue was renamed Kuibyshev street in honor of the revolutionary, Soviet political and party figure who died in 1935.
