Colorado portion of US Route 6

Colorado portion of US Route 6 is an epic journey that takes intrepid travelers from the Utah border to just east of Avon, weaving in and out of I-70 for some thrilling adventure. Experience a slice of Grand Junction through its Southside as you head into Rifle, then Silt and New Castle before making your way up toward Chacra. After departing Dotsero at the Colorado River’s confluence with Eagle River, US 6 reconnects briefly with I-70 again until Silverthorne where it ventures southward – bypassing Vail Ski Area but still giving you unforgettable views.

US 6 winds its way through Colorado with sensational sights to see. Starting in Clear Creek Valley, it meets I-70 at Loveland Basin Ski Area and travels eastward on the Eisenhower Tunnel’s eastern mouth before taking a scenic spin through the grandiose ravines of Clear Creek Canyon. Onwards from Golden, US 6 meanders south until again crossing paths with I-70, then making its way alongside Lakewood and into Denver via the ever iconic Sixth Avenue Freeway which further reveals an exciting journey ahead full of sharp turns as it heads north onto Interstate 25 before heading back East toward Vasquez Boulevard in Elyra Swansea.

US 6 navigates its way through Commerce City alongside US 85 and briefly follows the path of SH 2 before striking out on its own. The roadway meanders northeast until it joins I-76 for a portion outside Brush, then again continues east across Sterling with I-76 Business at its side. Eventually reaching Nebraska’s border, the final Colorado town along this route is Holyoke.
