Katsushika Harp Bridge

The bridge spans across Ayase River with two asymmetrical towers of 65 and 29 meters, connected by 48 steel cables in an S-shaped curve configuration.

Opened on September 9, 1987, this engineering project introduced the world's first curved cable-stayed bridge design as part of Tokyo's Central Circular Route.

The name originated from a public contest, drawing inspiration from the musical instrument due to the bridge's distinctive cable arrangement resembling harp strings.

The four-lane structure extends 455 meters in length and 18.5 meters in width, serving as a critical connection between Higashi-Yotsugi and Nishi-Shin-Koiwa neighborhoods.

The bridge features 30 lighting poles that illuminate its towers during nighttime, creating distinct reflections on the confluence of Ayase and Nakagawa rivers.
