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.
–By comparing this image with the previous posting, it is clear that these postcards are colorized, as the colors do not match. This image likely dates from the 1930s.
