The top flanges of the trusses, floor beams, and stringers are made flush, and are covered over with a solid floor of five-sixteenth inch flat plates. To handle the material a special traveler was designed and con- structed at the works of the Pennsylvania Company, shipped to Asia with the bridge material, and put together at the gorge. This is by far the largest traveler ever built, having an overhang of 165 feet.
