During the operating life of the Colorado Springs and Cripple Creek District RR (the Short line) many of the original wooden trestles were filled in with waste rock from the Cripple Creek mines. More were filled in later when it became first the Corley Mountain Highway, and then the Gold Camp Road.
In 1982, one of the reservoirs for the city of Cripple Creek failed, and washed out one of the larger fills between Gillett and Cripple Creek. Underneath the fill the trestle was almost perfectly preserved except for the deck, which had been removed. I have not been up there in years, but the last time that I was up there, the Gold Camp Road was regraded around the remains, and they were still there.
