1935 Joseph Stalin's master plan of Moscow provided for expansion of Garden Ring to at least 30-40 meter width, and demolition of buildings set at the ends of Garden Ring boulevards to create wide open squares. Grand Stalinist buildings, envisioned on all the ring, were initially planned only for major squares like Kursky Rail Terminal Square and Triumphalnaya Square. However, one end-of-boulevard block survives, precisely on Triumphalnaya Square, atop the six-lane tunnel. The same plan required removal of tram tracks in line with Moscow Metro construction. In fact, removal of tram tracks proceeded well in advance of subway construction; by 1938, tram remained only in southern and south-eastern segments of the Ring (this segment was closed in 1961 ).
