"Built in 1912 the Beaver Creek Bridge is one of the oldest reinforced concrete deck girder bridges on the Oregon State Highway System. The 40-foot structure has arched fascia girders and an architectural railing that is typical of Oregon bridges built during the decade from 1910-1919. The bridge was built by Multnomah County and has served on the Historical Columbia River Highway since the highway was constructed."
