Jefferson County, CO – Drivers traveling through the foothills west of Denver are facing major disruptions today after a semi-truck blocked both southbound lanes of Highway 285, forcing a full closure in Jefferson County.
According to the Jefferson County Sheriff’s Office, the closure is impacting southbound Hwy 285 between Parmalee Gulch Road and Highway 8 after a semi-truck became stuck across the roadway. Authorities say the truck is blocking both lanes, making travel through the area impossible at this time.
The incident was reported today, and photos from the scene show snowy, icy road conditions as crews work to manage traffic and assess the situation. Emergency responders and law enforcement are on site, and drivers are being turned around or diverted away from the closure.
Highway 285 is a critical commuter and mountain access route connecting Jefferson County to the Denver metro area, including communities such as Morrison, Conifer, and Bailey. The closure is expected to cause significant delays, especially during peak travel hours.
Officials have not yet provided an estimated reopening time. Motorists are advised to avoid the area, use alternate routes if possible, and allow extra travel time if heading toward the foothills or returning to the Denver metro.
No injuries have been confirmed as of this update, and the cause of the semi-truck incident has not been released.
Drivers should continue to monitor updates from the Jefferson County Sheriff’s Office and Colorado traffic authorities as conditions develop.
