A close-up view of UP's Harahan Bridge which was built in 1916. The ramp structure on the side was used by automobiles before 1950. The structure was covered with wooden blanks which, so I've been told, made for an interesting trek across the Mississippi. The bridge enjoys the history of having been the east to west link for the Rock Island, Missouri Pacific and Southern Pacific railroads back in the day. It is the current Mississippi River crossing structure for the Union Pacific Railroad.
