I-70 will be closed in both directions from 8 p.m. to 6 a.m. The detour will take drivers on and off the highway using the exit ramps.

“Weather is one of the most important factors in when we schedule construction work, especially when we’re working along the I-70 mountain corridor,” CDOT Region Transportation Director Tony DeVito said in a statement. “This work was originally scheduled for last week, but was postponed due to the recent winter storms. We now have to take advantage of this window of opportunity when we have the weather in our favor and equipment available.”
