"The main structure passes over about 60 railroad tracks of the Pennsylvania Railroad, Baltimore and Ohio railroad and the Pittsburgh and Lake Erie railroad." |
This is the photo that motivated this research. The McKeesport-Duquesne Bridge is the one in the background, and the
GAP Trail/US Steel/Pennsy+B&O Bridge is the one in the foreground.
The bridge goes bluff-to-bluff, but they had to remove some of a bluff to connect some of the approach roads.
