The McMillin Bridge (also known as the Puyallup River Bridge) is a concrete half-through truss bridge crossing the Puyallup River, in Pierce County, Washington, built in 1934. The main span of the bridge is 170 feet (52 m) long, which was the longest beam span or concrete truss in the US when it was
built. It was part of State Route 162 until it was replaced by a new span in 2015.
