The Aigiōhashi Bridge (愛岐大橋, Aigi ōhashi) is a truss bridge over the Kiso River in Japan. It is an iron beam bridge which connects Kakamigahara in the Gifu Prefecture with Inuyama in the Aichi Prefecture. The bride is part of Aichi-Gifu Prefectural Route 17, known as the Kōnanseki Route. The bridge is an essential link in the route from Nagoya and Komaki in Aichi Prefecture to Kakamigahara, Seki, and Gujō in Gifu Prefecture. Because there are no other bridges for 4 kilometres (2.5 mi) up- or downstream, the bridge is generally congested all day.
