The McKenzie River Bridge at McKenzie Bridge was a very unique structure that was designed by the Oregon State Highway Department under State Bridge Engineer Conde B. McCullough.
The bridge featured one of a kind details such as the 100-foot long concrete encased steel pony truss that is shaped to appear as an elegant concrete arch bridge. The 100-foot main truss was suspended between two 15-foot long reinforced concrete cantilevered arched arms giving the main span a total length of 130-feet.
The approach spans consisted of 50-foot long reinforced concrete girders with the exterior girders arched to seamlessly blend with the arched main span.
The bridge featured a a 24-foot wide roadway and 4-foot wide sidewalks along each side protected by a standard OSHD baluster railing that is still seen on many of Oregon's remaining concrete bridges from the era.
The bridge was built in 1929 and was replaced with a pre-stressed concrete box girder bridge in 1968.
