All lanes of C-470 were back open shortly after 8 a.m.
CDOT also reported a crash on C-470 at Ken Caryl Avenue due to a crash in the eastbound lanes. That crash has since cleared, as well.
Weld County officials reported a crash on Highway 85. That highway was closed between CR-90 and CR-96 but officials expected the road to reopen fairly quickly.
There were several other, smaller crashes around the area and multiple law enforcement agencies said they were on "accident alert," meaning officers would be focusing their efforts on responding to major crashes, such as those involving injuries.
