Expressways

Junctions, tunnels and long-span bridges of the expressway network that threads through Tokyo and the Kanto region.

Goshikizakura Bridge Adachi City A double-deck Nielsen-Lohse arch bridge spanning the Arakawa River on the C2 Central Circular Route, opened in December 2002 as the world's first bridge of its type.

Daikoku Junction Tsurumi Ward, Yokohama City The interchange where the Shuto Expressway Bayshore Route and Kanagawa Route 5 Daikoku Line meet, in Daikoku-futo, Yokohama. Its intricately curved ramp geometry, designed using differential geometry, forms a distinctive aerial pattern above one of Yokohama Port's main freight districts. Opened December 1994.

Tokyo Bay Aqua-Line / Umihotaru Kawasaki City, Kanagawa – Kisarazu City, Chiba A 15.1 km sea-crossing expressway linking Kawasaki and Kisarazu across Tokyo Bay, with a 9.5 km undersea tunnel (Aqua-Tunnel) and a 4.4 km overwater bridge (Aqua-Bridge). The midpoint artificial island, Umihotaru, offers 360-degree views of the bay. Opened December 1997.

Edobashi Junction Chuo City The first junction ever built on the Shuto Expressway, opened on 21 December 1963 above the Nihonbashi River in Chuo City, where the Inner Circular Route (C1) and several radial lines converge at one of central Tokyo's most consistently congested interchange points.

Nihonbashi Expressway Undergrounding Chuo City / Chiyoda City A ¥320 billion project to move 1.8 km of the Shuto Expressway's Inner Circular Route underground between Kandabashi and Edobashi junctions, dismantling the elevated structure that has shadowed Nihonbashi Bridge since 1963 and restoring open sky above the river by 2040.

Hakozaki Junction Chuo City The most structurally complex junction on the Shuto Expressway, where the Inner Circular Route (C1), Route 6 (Mukojima Line), and Route 9 (Fukagawa Line) converge in Nihonbashi Hakozaki-cho, Chuo City. A right-turn rotary embedded within a four-tier elevated structure earned it the nickname 'King of Junctions'.

Ohashi Junction Meguro City A four-tier loop interchange in Ōhashi, Meguro, connecting the elevated Shibuya Route with the underground Central Circular Route (C2). Its enclosed shell roof has been transformed into Meguro Sky Garden, a 7,000 m² circular public park running 400 metres around the loop.

Bayshore Route (B) Yokohama / Kawasaki / Ota / Koto / Edogawa / Ichikawa A 62.1-kilometre arc of expressway tracing Tokyo Bay from Yokohama to Ichikawa in Chiba, opened in stages between 1976 and 2001. The route links Haneda Airport, Odaiba, Toyosu, and the port logistics zones of Kawasaki in one continuous corridor.

Central Circular Route (C2) Shinagawa / Meguro / Shinjuku / Itabashi / Edogawa and more Tokyo's second ring expressway, completed on 7 March 2015 as the first of the Greater Tokyo three-ring network to open in full. At its core is the Yamate Tunnel — 18.2 kilometres long, Japan's longest road tunnel and the world's longest expressway tunnel.

Inner Circular Route (C1) Chiyoda / Chuo / Minato A 14.8-kilometre loop of elevated expressway encircling central Tokyo, opened in stages from December 1962 to 1967. The backbone of the Shuto Expressway network, C1 threads above rivers, moats, and filled canal beds through the heart of the city.
