The Hakucho Bridge is located at the entrance of Muroran Port, connecting the new development zone and the industrial and commercial center of Muroran City, Hokkaido. It was completed and opened to traffic in 1988 and was the first section of the Hakuchō Shindō that is signed as an alternate route of Japan National Route 37.
The Hakucho Bridge is the first suspension bridge in Japan to use a streamlined steel box girder structure. The suspension bridge's white and elegant steel structure is as impressive as a white bird spreading its wings. The decorative lanterns emit a swan-white light at night, and the bridge's skeleton emerges very beautifully.
This long white bridge has become a famous landmark like a silk belt across the sea. It appeared in the film "Detective Conan: Magician of the Silver Sky" as an important location.
