The Royal Gorge Bridge is located near Canon City, CO. It was built in 1929 and was the highest bridge in the world until 2001 and the highest suspension bridge in the world until 2003. It is still the highest bridge in the country (955 ft. above the Gorge). Amazingly it took only six months to build at a cost of $350,000, an estimated $20 million today. And this was at the start of the Great Depression! The first photo shows the 1929 dedication, the second is from the 1940s, and the fourth shows the Chicago White Sox in 1910 at the Hanging Bridge, which was built over the Gorge in 1879 and is still in use.
