Info from a "remember when" column in the local paper under the heading "75 years ago", publication Dec 2004:
The first wedding to take place on the world's highest suspension bridge over the Royal Gorge took place Sunday. The bridge is 1,050 feet above the ground. Mrs. Estella Bratton of Pueblo, CO and Sam L. Argus a Pueblo railroader, were married in the center of the suspension bridge.
