Description 

Pair of trestles on the historic Moffat Road, just east of Rollins Pass. Bypassed by the Moffat Tunnel in 1928; the rails were removed in 1935. The trestles were reopened as part of a road from 1955-1979. They have not been open to cars or pedestrians since 1979, though the trestles still carry an active natural gas pipeline.

Listed as a "Covered Railroad Bridge" because these trestles were covered by snowsheds during their use as an active railroad line.

These trestles are a notable engineering achievement for crossing extremely difficult rockslide terrain.
