Project Description

Federal Highway Administration, Central Federal Lands Highway Division (FHWA-CFLHD) in cooperation with Chaffee County, the U.S. Forest Service, Pike and San Isabel National Forests are making improvements to Cottonwood Pass Road. The project begins at the summit, where the CO FLAP 209(1) Cottonwood Pass project ends, and would continue 18.5 miles east to County Road 321 at the Town of Buena Vista western limit. The upper 0.5 mile section is proposed to be widened and shifted into the cut slope to avoid an embankment failure slipout, address failing guardrail, and to provide a rockfall storage area. Rehabilitation is proposed for the remaining 18 miles, including subgrade stabilization; rock scaling, guardrail replacement, select culvert replacement and installation, signing and striping, pulverization, and asphalt. Additionally, a 6-foot wide bike lane will be built on both sides of the road, from County Road 342 to 321. These bike lanes would connect with existing 6-foot wide bike lanes within the Town of Buena Vista.
