旭川大橋, Steel arch bridge in Asahikawa, Japan

The Asahikawa Ohashi is a bridge over the Tōbetsu River in Asahikawa, Hokkaido, carrying National Route 12 (Daiba 4-jō-dōri). It is the furthest downstream bridge on the Tōbetsu and the only bridge on the stretch between the confluence with the Biei River and the Tōbetsu's mouth at the Ishikari River. It links the city centre with the Kamui district.

The Asahikawa Ohashi opened in 1969 (Showa 44) as a bridge of National Route 12 (Daiba 4-jo-dori). It is the lowest bridge on the Chubetsu River and the only crossing between the point where the Biei River joins the Chubetsu and the Chubetsu's own confluence with the Ishikari River.

The bridge carries National Route 12, known locally as Daiba 4-jo-dori, and links the city centre with the Kamui district. On the Kamekichi and Akebono side it meets 1-jo-dori, while on the Chuuwa and Kamui side it joins Hokkaido Route 90, the Asahikawa Ring Road. Three riverside plazas sit beneath it: two on the right bank, upstream and downstream, and one on the left bank.

Taking the bus to Tokiwa-koen stop provides the most direct access, followed by a short walk of around 200 meters to reach the bridge. It sits about 1.8 kilometers from JR Asahikawa Station.

The bridge carries National Route 12 and is the lowest crossing of the Chūbetsu River; downstream of the Biei confluence it is the only bridge until the Chūbetsu meets the Ishikari. Three riverside plazas sit beneath it, and the Hokkaido Chūō Bus Asahikawa office stands nearby.
