相模川橋梁, Railway bridge in Hiratsuka, Japan
The Sagamigawa Bridge carries the Tokaido Shinkansen line across the Sagami River, connecting the areas between Samukawa and Hiratsuka in Kanagawa Prefecture. The structure uses continuous steel trusses designed to meet the demands of high-speed rail operation.
The bridge opened on October 1, 1964, marking the start of Japan's high-speed rail system linking Tokyo with western regions. It became a critical part of the country's modernized transportation network during the post-war period.
The bridge showcases engineering skill through its Warren truss design, which keeps bullet trains stable as they cross the river. Visitors can appreciate how this structure supports one of Japan's most important transportation routes.
You can watch Shinkansen trains pass from Hiratsuka City Okami Sports Ground, which is reachable by bus from either Hiratsuka or Hon-Atsugi Station. The afternoon hours tend to offer more frequent train sightings for those interested in watching.
The steel trusses create an optical illusion where the structure appears as one connected piece rather than separate segments. This design choice adds both visual continuity and structural strength to the crossing.
