After building The Broadmoor, Spencer Penrose began to develop Cheyenne Mountain property that he purchased on the northern peak in 1915. He built the Cheyenne Mountain Highway in 1925. Initially called the Broadmoor-Cheyenne Mountain Highway, it began one mile south of The Broadmoor at the Old Stage Road and ascended to the summit with 32 switchback turns up the mountain, gaining almost in altitude with a maximum 10% grade. It afforded views of Colorado Springs and Pikes Peak.
