The Mount Blue Sky Highway Project will reconstruct 0.7 miles of Colorado State Highway (SH) 5 in Clear Creek County, Colorado. The project is located approximately 50 miles southwest of Denver in the Arapaho and Roosevelt National Forest. SH 5 is designated a Scenic Byway and provides access to the top of Mount Blue Sky, which is the highest paved road in the United States. The project area is adjacent to Summit Lake Park located at 13,000 feet above sea level. The area receives on average 292 inches of snowfall per year with temperatures ranging from 65 to -40 degrees Fahrenheit. The project traverses between United States Forest Service and Denver Mountain Parks Lands. The Highway will remain closed for the duration of the project and will reopen for the season in 2026.
