This project aimed to upgrade the previously planned cable-stayed bridge to a higher-quality design. The concept focused on harmonizing with the open riverside of the Tama River and the surrounding mountain ranges, including Mount Fuji, Mount Takao, and Mount Kagenobu. Through refined details—such as streamlined cable anchoring that follows the flow of forces, seamless connections between the towers and piers, The shape of the main girder, which integrates the functions of a railing and wind-resistant fairings, features a seamless surface design that reduces maintenance needs. By minimizing the required structural elements while fulfilling functional demands, the design achieves an open bridge deck space that maintains visual continuity with the river landscape. A high-quality bridge can be achieved through the integration of refined, engineering-driven details. The bridge is a 330-meter-long road bridge with a main span of 165 meters.
