The Yale Bridge or Lewis River Bridge spans the Lewis River near Yale, Washington. It was built in 1932 by Cowlitz and Clark counties. The suspension bridge has a clear span of 300 feet (91 m), with a total length of 532 feet (162 m), replacing a previous steel truss bridge at the site. Construction of the Ariel Dam had created Lake Merwin with a water depth of 90 feet (27 m) at the site, requiring a new bridge that did not need to have support piers in the water. The road deck, stiffened by a steel Warren truss, is 50 feet (15 m) above the high water line of the reservoir.
The Columbia River Bridge at Wenatchee, Washington, also known as the Old Wenatchee Bridge and W.T. Clark Pipeline 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.
