Siuslaw River Bridge, Spanning Siuslaw River at Oregon Coast Highway, Florence, Lane County, OR

description

Summary

Significance: The Siuslaw River Bridge is historically significant as one of five Depression-era bridges that completed the Oregon Coast Highway. For Oregon's southern coastal region, the completion of these bridges is considered the dividing line between a period of relative isolation and dependence on sea transportation, and its modern era of land transportation and connection with the hinterland. The Siuslaw River Bridge is the only one of the five PWA coastal bridges with a bascule span. The bridge is also representative of the innovative designs by State Bridge Engineer Conde B. McCullough, a pioneer in American concrete bridge design. The Siuslaw River Bridge is an early example of McCullough's use of tied arches and Considere-type hinges.
