Kōhoku Bridge

Kōhoku Bridge is a road bridge crossing the Arakawa River with a steel arch structure measuring approximately 449 meters long and 11 meters wide. It features separate lanes for pedestrians and cyclists to manage different types of traffic flow.

The original wooden structure was built in 1923 but sustained damage during the Great Kanto Earthquake and was rebuilt in 1925. The current steel arch design replaced it entirely in 1972.

The bridge stands near the former Arakawa embankment, known for its five-colored cherry trees, which held national scenic spot status.

The crossing accommodates both pedestrians and cyclists, though bicycles must be walked in certain zones for safety. Lighting along the structure makes nighttime crossing safe and visible.

Fluorescent lights installed along the railings significantly reduce nighttime traffic accidents. This safety feature is an unusual design choice for bridges in the region.
