WHOLE SYSTEM. WHOLE SAFETY.  

To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project 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.

COVID-19

Safe transportation infrastructure is essential for emergency first responders and freight drivers as Colorado navigates the COVID-19 pandemic. With that in mind, construction continues on CDOT projects with social distancing and other measures to reduce COVID-19 exposure on the worksite. The Colorado Department of Public Health and the Environment has promulgated guidelines for construction activities. Gov. Polis announced an emergency, temporary stay-at-home order for all of Colorado, which went into effect March 26. With this order, the public is urged to #DoYourPartCO and avoid all nonessential travel. With fewer vehicles on the roads, CDOT crews will be able to work more efficiently and safely.

ABOUT CDOT

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.
