This image shows a view of the Hanging Bridge from the opposite side of the previous posting, with a better view of the support beams and cabling, and a clearer view of the unsupported underside of the bridge.
The description states:
HANGING BRIDGE IN THE ROYAL GORGE
The Grand Canyon of the Arkansas is nearly ten miles in length, extending from near Canyon City to Parkdale. About midway is the Royal Gorge, the deepest and narrowest part of the Canyon, where the walls rise to a height of 2,500 feet and the river channel is so restricted that the railroad is carried over the stream by a bridge suspended from the rocks above.
–This image likely dates from the 1930s.
