DENVER (KDVR) — Eastbound and westbound lanes of Interstate 70 between Washington Street and Interstate 270 will close from 10 p.m. May 21 to 5 a.m. May 24 as part of Colorado Department of Transportation’s Central 70 Project.

Roads will be shut down so crews can prepare for the Mile High Shift. The Mile High Shift will move six lanes of I-70 from the existing viaduct to the future westbound lanes between Brighton and Colorado boulevards.
