America got its highest suspension bridge at 956 feet above Royal Gorge’s floor in 1929.
At 890 feet over the Colorado River, it is the world’s highest concrete arch bridge and America’s second-highest.
Standing 876 feet high, 3,030 feet long, with a 1,700-foot long steel arch, this bridge was designed by Michael Baker Company and cost $37 million to construct.
The construction of this 2,428 feet long bridge took an estimated $13 million.
A unique, horseshoe-shaped bridge standing 720 feet high and 70 feet wide, the Grand Canyon Skywalk is all things mind-blowing.
