DENVER ( KDVR ) — Northbound US 85 and east and westbound US 34 in northern Colorado will experience nightly closures from 9 p.m. to 5 a.m. starting Monday to allow for the installation of overhead signage as part of a larger project aimed at improving safety.
The Colorado Department of Transportation (CDOT) is advising drivers to take alternate routes during those hours, which the agency said are weather-dependent and subject to change.
