Rockfall mitigation set for US 285 Kenosha Pass week of May 4

Travel Advisory

May 4, 2020 - Southeastern Colorado

Park COUNTY ― The Colorado Department of Transportation will be performing rockfall mitigation on US 285, Kenosha Pass at mile point 205.5, between Jefferson and Grant, the week of May 4. The rock fall mitigation operations should take about a week, as crews install netting on the rock face to reduce future rockslide activity.

US 285 Rock Scaling Operations


A rock scaling operation took place at the location in late April. Rock scaling is the removal of loose rock from slopes. Any loose surface material on a cliff or slope could present a rock fall hazard for motorists on the highway. 

HIGHWAY TRAVEL IMPACTS: Beginning Monday, May 4, during daytime hours, motorists will encounter up to 10 minute delays, during daytime hours, on US 285 Kenosha Pass at mile point (MP)205.5. The traffic stops will allow crews the opportunity to install the netting on the rock face. The rockfall mitigation operations are expected to be completed by Friday, May 8.

Safe transportation infrastructure is essential for emergency first responders and freight drivers as Colorado navigates the COVID-19 pandemic. With that in mind, road maintenance and construction continues on CDOT projects with social distancing and other health safety measures to reduce COVID-19 exposure on the worksite. The Colorado Department of Public Health and Environment announced guidelines for construction activities. The public is urged to join the campaign for #DoingMyPartCO by practicing social distancing, wearing face masks, staying at home when possible, and avoiding nonessential travel. With fewer vehicles on the roads, CDOT crews will be able to work more efficiently and safely. 


In early 2019, 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 interregional express service. Governor Polis has charged CDOT to further build on the state’s intermodal mobility options.
