Hosting the Games brought about improvements to Nagano's transportation networks with the construction of the high-speed "shinkansen" line, the Nagano Shinkansen (now the Hokuriku Shinkansen), between Tokyo and Nagano Station, via Ōmiya and Takasaki. In addition, new highways were built, including the Nagano Expressway and the Jōshin-etsu Expressway and upgrades were made to existing roads.
