The bridge was originally constructed in 1935 as a railway crossing for the JNR Saga Line.
The structure is officially recognized as a Registered Tangible Cultural Property of Japan.
The central section of the bridge is a lift span, designed to be raised vertically to accommodate boat traffic on the Hayatsue River.
The bridge spans approximately 500 meters in total length.
The tracks were removed following the closure of the Saga Line, allowing the bridge to be repurposed specifically for pedestrian and bicycle traffic.
The park is situated at the border between Saga City and Yanagawa-adjacent regions, serving as a gateway to the Ariake coastal area.
Morodomi Steel Bridge Tenbo Park is a waterfront recreation area centered around the historic former railway bridge of the Saga Line. The bridge is a designated National Registered Tangible Cultural Property known for its distinct red steel lattice structure. The park features an elevated pedestrian walkway that allows visitors to walk onto the bridge spanning the Hayatsue River. The site was once part of the Japanese National Railways, which ceased operations in this sector in 1987. The park serves as a hub for local cycling routes and riverside birdwatching. The surrounding landscape provides views of the Ariake Sea basin. The bridge's architectural design features a rare movable section once used to allow vessel clearance.
