Oregon City Bridge Axis View South Portal Looking North

Oregon City Bridge (1922) is a steel through arch bridge spanning the Willamette River between West Linn and Oregon City in the Portland metropolitan area, carrying Oregon Route 43. The bridge was designed by Conde B. McCullough, completed in 1922 and stands alone as the only bridge in Oregon to be encased in gunnite (shotcrete), which protected the steel structural members from corrosive sulfur dioxide emissions from the former paper mills south of the bridge. Notable features include McCullough’s signature detailing in the obelisk pylons, ornate concrete railings, Art Deco piers and Art Deco light sconces. The piers were designed to accommodate public restrooms, and observation balconies; these were closed and sealed in 1937. In 2005 the bridge was added to the National Register of Historic Places. Clackamas County, Oregon, USA.
