Imari Bay Bridge is located in Imari Port, Imari City, Saga Prefecture, and is a bridge (arch bridge, partially reinforced concrete ramen bridge) that connects Kusuhisa, Yamashiro-machi and Seto-cho in the same city.
It was constructed as a part of the Imari Port harbor road with the primary purpose of facilitating logistics in the port by directly connecting the Imari Port Nanatsujima area and the Kuhara Minami area. In addition, it has also contributed to shortening the route between Fukuoka and Karatsu cities and the northern part of Nagasaki prefecture by short-circuiting National Route 204.
