UPDATE: Two people involved in the crash have been transported to St. Mary's Hospital with unknown injuries.  All westbound lanes are now reopened.  The driver and vehicle were out of Missouri.

Just before 9am we started to hear reports of a single vehicle rollover in the westbound lanes of I-70 near mile marker 58. Trooper Reid with Colorado State Patrol tells us an ambulance is en route to the scene and the left lane is blocked at this point by debris. The vehicle is a maroon Dodge pickup. There's no word on injuries, but radio traffic was reporting three of the occupants were walking around following the crash.
