This project involved the relocation of the Vantage Ferry Bridge over the Columbia River to accommodate the Lower Monumental Lock and Dam project for the U.S. Corps of Engineers. The two-lane, steel cantilevered bridge, has a main span length of 1000’ and a length overall of 2040’. It is currently known as the Lyons Ferry Bridge and carries State Route 261 over the Snake River.
This is the oldest extant steel cantilevered bridge in the State of Washington. It is a good example of early-twentieth century cantilever bridge construction using carbon steel. The structure served first at Vantage Ferry on the Columbia River and then was dismantled and re-erected on the Snake River at Lyons Ferry. |
