The Columbia River Bridge at Wenatchee, Washington, also known as the Old Wenatchee Bridge, was built by the Washington Bridge Company in 1908, primarily as a means to carry irrigation water pipelines across the Columbia River. It was the first road bridge over the Columbia south of Canada. The bridge is a pin-connected cantilever truss, 1,600 feet (490 m) long, with one 200-foot (61 m) Pratt truss between two 160-foot (49 m) cantilever arms, with 240-foot (73 m) side arms and a 60 feet (18 m) girder span. The bridge was purchased by the Washington highway department for $182,000 for highway use. As originally built, the bridge carried a 20.5-foot (6.2 m) wide timber roadway, with additional ability to carry a street railway. However, the east approach to the bridge was built at a 6% grade, limiting its potential.^[3]

The bridge was replaced in 1950 by the Senator George Sellar Bridge. The next year the Wenatchee Reclamation District bought the bridge for $1.00, moving the pipes from outside the truss to within. The bridge was opened to foot traffic.^[3] In 2007 concerns were raised about the bridge's ability to sustain foot traffic.^[4] Repairs were made in 2010.^[5]

The bridge was placed on the National Register of Historic Places on July 16, 1982.^[2]
