Current I-25 Traffic Impacts and CDOT Safety Measures
Beyond the major accident scenes, travelers on I-25 must also contend with numerous ongoing traffic impacts and construction zones managed by the Colorado Department of Transportation (CDOT). These factors contribute to congestion and increase the likelihood of further incidents if drivers are not vigilant.
Ongoing Traffic Alerts and Closures
- Speed Limit Reduction: CDOT has lowered the speed limit on a major project stretch of I-25 between Mead and Berthoud to 65 mph.
- Off-Ramp Closure: The southbound I-25 off-ramp at WCR 34 (Weld County Road 34) is currently subject to closure, particularly on Sunday mornings.
- Frontage Road Closure: The I-25 East Frontage Road access to WCR 34 is scheduled for a permanent closure in January, a change that will impact local traffic flow around the Mead and Berthoud areas.
- Weather-Related Safety Concerns: Recent reports indicate that multiple highways, including parts of I-25 in Northern Colorado, have been shut down due to "safety concerns" amid snowy conditions and severe weather, leading to interstate closure. A multi-car crash near Pikes Peak Raceway was a direct result of snowy I-25 conditions.
The Colorado State Patrol (CSP) is maintaining a visible presence near high-incident areas like Crossroads Boulevard to enforce the reduced speed limits and monitor for aggressive driving. Drivers are urged to obey all posted speed limits, especially the 65 mph zone, and to check the CDOT website or Twitter for the latest Denver traffic news and real-time updates before beginning any journey.
