DENVER --  The Colorado department of Transportation closed I-70 in both directions from C-470 in west metro Denver all the way to Idaho Springs. The closure was due to multiple accidents. CDOT warned drivers to expect long delays. There was no estimate on when the highway would reopen as of 9:30 p.m.

CDOT said late Wednesday that dozens of vehicles, possibly as many as 50, were either crashed or stranded along the highway.

Earlier, a 20 car pile-up closed I-70 Eastbound near Lookout Mountain on Wednesday afternoon.

The closure was between mile markers 256 - 260 on I-70.

Evergreen fire rescue reported several injuries from the crash.

Extreme ice on the road could be a factor in the multi-car accident.

With snowfall in full swing just in time for the afternoon rush, officials are warning drivers to take it slow out there.

As snow falls on the metro area, temperatures will drop into the upper 20s by 5 p.m.

Time frame for heaviest snow looks to be 4-11 p.m.  Snow continues overnight then tapers off mid to late morning Thursday.

I-25 still looks like the dividing line with totals of 1-4” to the east and 5-10” to the west. The Foothills could see 8-12” totals with a few over a foot possible.
