 The first section of the Ueno Route between Edobashi and Honchō was opened to traffic on 21 December 1963.The second section to be completed between Honchō and Iriya was finished on 31 May 1969.Plans were made to extend the radial route north to the Central Circular Route in 1992; however, they have been shelved due to geographic constraints and a lack of support among residents of the area that would be impacted by an extended Ueno Route.
