From an 1891 report to the Board of Railroad Commissioners: "This bridge consists of three through spans, length 163 feet, 241 feet, and 264 feet respectively, center to center of end pins, and one deck span of 20 feet, five of 30 feet, six of 50 feet each and one of 60 feet, all double track. The spans rest at all points except the abutments, on iron towers, the highest of which are 139 feet from masonry to top of tower."
The through spans were Whipple trusses (9-, 11-, and 15-panels respectively), while the deck spans were riveted double-intersection lattices.
:^)
BTW, there were more than two bridges with Triple Whipples ;^)
There was some really neat stuff out there. Too bad most of it is gone and forgotten.
