Shepperds Dell Bridge, Spanning Young Creek at Columbia River Highway, Latourell, Multnomah County, OR

Significance: Shepperd's Dell Bridge was designed by bridge designer K.P. Billner under the supervision of Samuel Lancaster in 1914. The bridge is a reinforced concrete deck arch with a 100-foot span. It was the second bridge built on the Historic Columbia River Highway. The solid curtain wall between spandrels and above the crown of the parabolic arch is a unique feature of this bridge. Later bridges of Conde B. McCullough's on the Columbia River Highway imitate this design. K.P. Billner believed this was one of the strongest and best-erected bridges on the highway. The structure harmonized beautifully with its hilly woodland setting.
