US Highway 6 Reopens

Thanks to the tireless efforts of the construction team, US Highway 6 opened to normal traffic patterns late last night. Thank you all for your patience last week. Here are a few shots of the construction from early last week.

Upcoming Highway Closure

A portion of US Highway 6, from the intersection of State Highway 119 west to the intersection of US Highway 40, will be closed March 22nd – March 28th.  At each highway bridge we will install an underpass as part of the eastern most section of CCC-3. We anticipate no impacts to traffic traveling west through the Canyon to Black Hawk and Central City . We will provide detailed information as the closure date approaches, but please see the map and photo simulation below for more information.
