I-70 Mountain Corridor Advisory ― Rockfall-related lane closure on westbound I-70

November 29, 2019 - Statewide News - Travelers should plan ahead, seek alternate routes

COLORADO ― A rockfall has closed the right lane along westbound I-70 near mile marker 236, east of Dumont. One lane remains open, but delays are already building, and travelers should expect backups to grow. Denver metro-area travelers looking to go to destinations in Summit County and further west should consider using US-285 to CO-9. More details will be made available as crews determine the extent of the issue.


Travelers are urged to “know before you go.” Gather information about weather forecasts and anticipated travel impacts and current road conditions prior to hitting the road. CDOT resources include:


Earlier this year, CDOT announced its Whole System — Whole Safety initiative to heighten safety awareness. This initiative takes a systematic, statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.


CDOT has approximately 3,000 employees located throughout Colorado, and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated inter-regional express service. Governor Jared Polis has charged CDOT to further build on the state’s multi-modal mobility options.
