While stopped at the stoplight at Superior Street and Second Avenue East this morning, I noticed a cable strung diagonally across the intersection. The cable is strung between Old City Hall and the Temple Opera building. It is a plain steel cable, not holding up any sort of utility cable. The cable looks fairly old, based upon the brackets fastened to the buildings. Anyone have any idea as to it’s purpose? Lightning? Keeping one of the buildings from falling over? Old traffic signals?
