Almost exactly 100 miles of I-70 closed Monday afternoon due to snow and safety concerns. The main Colorado artery shut down eastbound between E-470 (near Aurora) and the Kansas border, and westbound between the Kansas border and US-40 (near Limon).
That's approximately mile markers 386 to 486 eastbound, and 449 to 463 westbound.
Officials were not sure when it will reopen.
Multiple highways also experienced shutdowns on the eastern plains, including US-40.
The interstate closed at around 2 p.m. and was still shut late Monday night.
