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
