Significance: The Willamette River Bridge (commonly called the Oregon City Arch Bridge) is 745' long with a 360-foot steel through arch of box-girder construction, encased in gunite. The gunite encasement was necessary to prevent corrosion from sulphur dioxide fumes from the paper mills south of the bridge. This is the only gunite-covered bridge in Oregon. The 1921-1922 Biennial Report of the Oregon State Highway Commission praised this bridge as being "the most artistic appearing large bridge in the State."
