While snowfall varied across the state following Wednesday's storm, many roads and highways began to close down Wednesday afternoon to evening as the storm moved across the plains causing extremely dangerous driving conditions.

I-70 shut down Wednesday from the Denver Airport all the way to the Kansas border, as whiteout conditions caused multiple accidents according to Colorado State Patrol.

Snowflakes are still flying this evening, and along with 30-45 mph wind gusts over the eastern Plains, the weather has absolutely crippled parts of Colorado. As expected, the worst impacts have been occurring east of I-25. Winter Storm Warnings will not be allowed to expire over the northeastern Plains until 11 pm in some areas.

With the blizzard-like conditions, the big story has been the amount of road closures within the state. According to CDOT, here's the most current listing:
