Description

The Jōgakura Bridge is a 360-meter-long (1,180 ft) deck arch bridge that carries National Route 394 at a height of 122 meters (400 ft) above Jōgakura Creek. The bridge's main span has a length of 255 meters (837 ft).[1] It is the longest deck arch bridge in Japan.[2] The bridge is known as tourist destination because the panoramic views it affords of the Hakkōda Mountains in Towada-Hachimantai National Park. The Jōgakura Bridge becomes especially crowded with tourists when the surrounding Siebold's beech forests begin to change color during autumn.[3]

History

Jōgakura Bridge was opened to traffic on 27 October 1995, replacing an older bridge that was heavily impacted by the rapid deterioration of the columnar jointed andesite rock that it was built on. The total cost of its construction was 87 billion yen.[4]
