URGENT UPDATE: Northbound lanes of Interstate 25 are currently closed at 120th Avenue due to a serious crash involving a semi-truck and a passenger vehicle. Multiple individuals have been transported to the hospital following the incident, which was reported early this morning, December 28, 2025. Northglenn Police confirmed the developing situation in a post on X.
The precise extent of the injuries remains unclear, but authorities indicate that this incident will lead to an extended closure of the highway. Drivers heading north are being detoured off I-25 at 120th Avenue. This disruption is compounded by adverse weather conditions, as slick roads across Colorado are impacting travel.
As a cold front swept through the Denver metro area overnight, light snowfall created hazardous conditions on the roads, prompting the Colorado Division of Emergency Management to advise drivers to “leave early and give yourself extra time” if travel is necessary. They emphasized lowering speeds, as roads, while not heavily covered in snow, remain dangerous.
According to the National Weather Service, a band of snow moved southeast over the metro area just before 4 a.m., rapidly deteriorating road conditions. Winter driving hazards are also anticipated in the mountains, where snow accumulation from Saturday continues to affect visibility and road safety.
The city of Centennial is currently on Accident Alert, meaning that residents involved in minor collisions should file online reports instead of calling local authorities. This alert was issued at 8 a.m. today, highlighting the increased volume of accidents under the current weather conditions.
The 9NEWS Weather Impact Team has issued a Weather Impact Alert for expected snow and slick conditions throughout the day. Snowfall is expected to taper off as the sun rises, but additional light accumulation may occur, contributing to ongoing travel concerns.
With temperatures projected to remain below freezing early next week, concerns about black ice will persist, particularly on untreated roads and north-facing slopes. Travelers are urged to exercise caution during this time.
