The Indian Timothy Memorial Bridge is a tied-arch bridge which spans Alpowa Creek less than half a mile before that creek joins the Snake River, about 8 miles (13 km) west of Clarkston in Asotin County, Washington. It was built by the Washington State Department of Transportation in 1923 and was listed on the National Register of Historic Places in 1982.[1]

It is the only two-span tied arch bridge in the state, and one of only five concrete tied arch bridges. It has two 100 feet (30 m) arches, each of which has 20 feet (6.1 m) rise.[2]

It is named for Ta-moot-Tsoo (Chief Timothy), a Nez Perce Indian who lived from 1800–1891, who was "a true friend of the early settlers of Washington, Oregon, and Idaho."[2] Chief Timothy Park is located on Silcott Island in the Snake River, close to the mouth of Alpowa Creek.[3]

It was preserved when what is now U.S. Route 12 was widened, and stands roughly parallel to the existing route 12 bridge, about 100 feet (30 m) apart.[2][3]

The bridge was documented in the HAER program in 1993, with photography by Jet Lowe.
