Funabori Bridge, Road bridge in Edogawa-ku, Japan

Funabori Bridge, officially Shin-Funabori Bridge, carries Tokyo–Chiba Route 50 (Shin-Ohashi-dori) across the Arakawa, Nakagawa and former Nakagawa rivers. Its total length of 1,487.4 m makes it the longest bridge managed by the Tokyo Metropolitan Government; the Arakawa span is 524.05 m, with a 169.75 m Nakagawa span and a 559.97 m curved right-bank approach that includes the Funabori Kobashi over the old Nakagawa.

The current steel bridge opened on 17 July 1971, replacing a wooden predecessor about 400 m downstream that dated from 1923 and carried a 518 m span over the Arakawa flood channel. That old timber bridge, Tokyo's longest, was closed after a barge struck a pier on 2 October 1966 and dropped a 14 m section. The right-bank approach over the former Nakagawa, including Funabori Kobashi, was finished in December 1970, and part of the bridge was widened to 27.4 m in 1990.

The bridge carries Tokyo Metropolitan Route 50 (Shin-Ohashi-dori) and was designated a Tokyo priority emergency transport road for disaster response. Its structure incorporates the Funabori Bridge interchange of the Metropolitan Expressway Central Circular Route, and it runs parallel to the Toei Shinjuku Line Arakawa bridge just downstream.

The location is roughly 760 meters from Funabori Station, making it easily reachable for commuters. The pathways are clearly marked, and the infrastructure is straightforward to navigate for daily users.

The bridge crosses the Arakawa 3.5 km from the river mouth, and its total length of 1,487.4 m makes it the longest bridge managed by the Tokyo Metropolitan Government. The Arakawa span alone measures 524.05 m, with a 169.75 m span over the Nakagawa.
