紀之川橋粱, Railway bridge in Wakayama, Japan

The Kinokawa Bridge is a railway bridge on the Nankai Main Line between Kinokawa Station and Wakayamashi Station. The 1903 upstream track consists of three pin-connected Pratt trusses flanked by 16-span and 3-span girder sections, designed by Kimura Tsutomu and built by the American Bridge Company. The 1922 downstream track, built in Japan, uses three Warren trusses with the same girder arrangement.

The first bridge, the present-day up line, was built in 1903 and designed by Kimura Tsutomu, one of Japan's first railway engineers; it was manufactured by the American Bridge Company. A parallel down line, made in Japan, was added in 1922, doubling the track. In 1998 a replacement was considered over seismic concerns, but a Railway Technical Research Institute study found no problem and the plan was dropped. Both spans were certified as JSCE Selected Civil Engineering Heritage in September 2022.

The bridge is a railway crossing of the Kino River on the Nankai Main Line, between Kinokawa Station and Wakayama-shi Station. In September 2022 both the 1903 upstream track and the 1922 downstream track were certified as JSCE Selected Civil Engineering Heritage sites.

The bridge carries the Nankai Main Line between Kinokawa Station and Wakayamashi Station; it is a railway crossing, not a road. The nearest access is Kinokawa Station, about a 15-minute walk away. Look at the two parallel spans: the 1903 upstream track and the 1922 downstream track.

The 1903 upstream span was designed by Kimura Tsutomu, one of Japan's first railway engineers, and built by the American Bridge Company; the 1922 downstream span beside it is of domestic manufacture. Both were certified as JSCE Selected Civil Engineering Heritage in September 2022.
