JEFFERSON COUNTY, Colo. (CBS4) – A deadly crash on Interstate 70 heading west closed some lanes Sunday afternoon. Colorado Department of Transportation says the crash happened between the Chief Hosa and Evergreen Parkway exits.
Colorado State Patrol says a 47-year-old male motorcyclist died and only one vehicle was involved. Investigators believe speed was a factor, saying specifically the motorcyclist was traveling through a curve and drifted into the outside guardrail.
CSP says 911 callers reported seeing a group of motorcyclists speeding, swerving and cutting drivers off before the crash.
There were miles of traffic backup. Right lanes were blocked.
“Curiosity slowing impacting eastbound traffic. Please be mindful of traffic conditions ahead of you,” CSP said on social media.
