An old, unused railroad signal still stands on the former Illinois Traction System (ITS)/Illinois Terminal System (ITC) bridge in North St. Louis. The bridge originally carried electric interurban passenger trains from the McKinley Bridge to the ITS' train station (the former Globe Democrat newspaper building) in downtown St. Louis. At the time this photograph was taken, the bridge had been unused for many years. However, up until the summer of 2004, the bridge was used to bring in news print by boxcars for delivery to the St. Louis Post Dispatch, St. Louis' biggest daily newspaper. I was able to capture some photographs of the newsprint delivery in the spring of 2004, just a few months before the operation ended. You can see those photographs at this link.
