Route description

Ikebukuro Route at Gokokuji Interchange in Bunkyō.

Route 5 begins at Takebashi Junction with the Inner Circular Route in Chiyoda City just north of the Tokyo Imperial Palace. From there it travels northwest through Shinjuku, Bunkyō, Toshima, and Itabashi in Tokyo before crossing over the Arakawa River into Toda in Saitama Prefecture where Route 5 ends at Bijogi Junction where it intersects the Tokyo Gaikan Expressway. The expressway continues northward as the Omiya Route to Ōmiya-ku.[1]

The speed limit on the Mukojima Route is set at 60 km/h.[2]

History

The Ikebukuro Route was first opened in March 1967 between Nishi-kanda and the expressway's southern terminus at Takebashi Junction. It was extended to its current length in phases completed in 1969, 1977, 1990, and 1993.[3]

In preparation for increased congestion during the 2020 Summer Olympics, a new traffic-control system was installed along Route 5 at the interchanges at Kita-Ikebukuro, Nishi-Kanda, Gokokuji, Nakadai, Takashimadaira, Toda-minami, Higashi-Ikebukuro, and Iidabashi.[4]
