Due to additional flooding and erosion the single lane temporary closure evolved to an extended full closure. Plan for the road to be closed for the morning commute tomorrow (Tuesday 16th May 2023.) 


“Updated Today at 4:14 PM MDT by Colorado Department of Transportation – Between CO 93 (Arvada) and Twin Spruce Road (Coal Creek) from Mile Point 10.65 to Mile Point 17.5. Road closed expect delays because of flooding. Comment: Both directions closed to through traffic. Local traffic only to MM16 westbound, no through traffic permitted.”
