Full closures will continue through early June 2020 for the installation of a ramp metering system   

DOUGLAS COUNTY – A new ramp metering system to improve traffic flow on I-25 in Douglas County will be installed.  Construction is scheduled to begin this Sunday night, May 10th, with work taking place at night.  

The new ramp metering system will coordinate the rate of vehicles entering I-25 along 16 ramps in Douglas County.  This will allow blocks of vehicles to smoothly enter the highway avoiding side and rear collisions.

Detour routes range from one to 10 miles and will add up to 15 minutes in travel time depending on traffic volumes.  A detailed schedule is listed here.

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.
