Lower Yauza river had numerous bridges, dams and water mills since Middle Ages.
One was eventually demolished without replacement, three others correspond (west to east) to present-day Maly Ustinsky, Astakhovsky (Yauzsky) and Tessinsky bridges.
Most important of these, Yauzsky Bridge, connecting city center with eastbound roads, was rebuilt in stone in 1804.
[5] Before World War II, city planners intended to complete the Boulevard Ring with a link through Zamoskvorechye.
Maly Ustinsky and Yauzsky (Astakhovsky) Bridge were also torn down and rebuilt to the same high capacity standard.
Ring link was never completed; its planned outline can be vaguely traced by a chain of grand stalinist buildings near Tretyakovskaya metro station.
It was named after the nearby New Kriegskomissariat, a castle-like military depot (built 1778-1781); there is no relation to Red Commissars of 20th century.
