Oliver Swing Bridge
Posted December 26, 2015, by William Kearns (wkearns [at] columbus [dot] rr [dot] com)

In the 1950's my grandmother lived in Superior, WI, and I had an aunt, uncle, and cousin in Duluth. Occasionally we'd go over this bridge. it had a wooden deck and large steel columns came vertically thru the roadway holding up the RR tracks overhead. The last time I was in the area (about 1995), I was amazed to see this bridge still there and in use.
