Sasamuta Bridge, Stone arch bridge in Takeda City, Japan.

Sasamuta Bridge is a two-arch stone aqueduct bridge over the Sasamuta River in Hasamida, Takeda, Oita Prefecture. It carries the Waka-miya irrigation channel across the river and a road: 59.0 m long, 30.0 m high, 4.0 m wide, with arches spanning 21.5 m and rising 9.0 m. It was completed in 1917 to a design by Kudo Torahiko.

The stone bridge was built in 1917 after earlier water transport systems failed in the area. It replaced an iron pipeline that had collapsed and a temporary wooden structure that followed.

The bridge carries water from the Inaba River in Takeda to the Asaji district of Bungo-Ono as part of the Wakamiya irrigation channel. It is managed today by the Asaji Town Land Improvement District, and the channel still crosses the Sasamuta River and the road beneath it.

From JR Kyushu's Bungo-Taketa Station on the Hohi Line, take an Oita-bound Ono-Taketa bus and get off at the Nigoribuchi stop; the bridge is about a two-minute walk from there. The structure is an irrigation aqueduct, not a road bridge, so it is seen from the paths below rather than crossed.

The bridge is an aqueduct of the Wakamiya Iro irrigation channel, carrying water from the Inaba River in Takeda to the Asaji district of Bungo-Ono. Its two arches span 21.5 m each, with a rise of 9 m and a bridge height of 30 m. It was designed by Kudo Torahiko and is managed by the Asaji Town Land Improvement District.
