UPDATE: CDOT will close the Mamm Creek overpass on Garfield County Road 315 between Rifle and Silt. The work is now rescheduled to August 12-13, overnight from 11 pm to 3:30 a.m. The work is for deer guard replacement.

All traffic will need to use either Garfield County Road 346 or 352 to access I-70 during this time, as the guards will be removed, leaving an open trench during construction.
