Snake River Bridge at Lyons Ferry

Completed in 1968 by American Bridge, the Snake River Bridge at Lyons Ferry project consisted of the relocation of the Vantage Ferry Bridge over the Columbia River to accommodate the Lower Monumental Lock and Dam project for the U.S. Army Corps of Engineers. The two-lane, steel cantilevered bridge features a 1,000’ main span and an overall length of 2,040’. Now known as the Lyons Ferry Bridge, it carries State Route 261 over the Snake River. It is the oldest extant steel cantilevered bridge in the State of Washington and serves as a notable example of early twentieth-century cantilever bridge construction using carbon steel. Originally located at Vantage Ferry, the structure was dismantled and re-erected at its current location.
