新荒川大橋

Shin-Arakawa Bridge is a road bridge crossing the Arakawa River and connecting Kawaguchi in Saitama Prefecture with Kita Ward in Tokyo. The structure consists of two parallel spans completed in the 1960s and 1970s, together forming National Route 122.

The original bridge was completed in 1928, replacing a ferry service and becoming the longest bridge in Tokyo at that time. A second parallel span was added decades later to handle increasing traffic demands.

The bridge represents a daily crossing point where commuters and residents move between two prefectures, serving as a practical link in the region's urban fabric. It marks the boundary where Saitama and Tokyo meet, making it a significant geographical marker in everyday life.

The bridge is easily accessible when traveling between the two prefectures by car or public transport. Pedestrians and cyclists can cross the structure, though they should be aware of steady vehicle traffic as this is a well-used transportation route.

During the 2011 earthquake, the tsunami passed beneath the bridge without damaging it, making it a notable point of resilience during that disaster. This event highlighted how the structure was designed to withstand natural forces affecting the region.
