The Fairfax Bridge is a steel-lattice three-hinged arch bridge spanning the Carbon River on State Route 165 in Pierce County, Washington. Previous to the construction of the bridge in 1921, the only route south to the area around Fairfax was by train. At a total cost of $80,000, the bridge's deck sits 250 feet above the river. Being a single-lane bridge, vehicles must yield to oncoming traffic already on the bridge.
The bridge was added to the National Register of Historic Places in 1982. From Wikipedia
