Southwestern Colorado Rumble Strip Installation
About the Project
The Colorado Department of Transportation and Surface Preparation Technologies (SPT) will be constructing rumble strips along sections of fourteen highways in southwest and south central Colorado.
The project will include centerline mill work for rumble strips and pavement markings in twelve counties: Alamosa, Archuleta, Conejos, Costillo, Dolores, Huerfano, Montrose, Montezuma, Rio Grande, San Miguel, La Plata, and Saguache.
A total of 268 miles of roadway will be improved with the centerline rumble strips along segments of the following highways: Colorado Highways 90, 97, 141, 184, 172, 151, 114, 15, 136, 368, 370, and 150; and US Highways 160 and 550.
Rumble strips are an effective measure for reducing roadway departure crashes. Grooves are cut into the pavement which cause a vibration and rumbling sound when the tires of a moving vehicle come in contact with the cut pavement. The noise and vibration produced by rumble strips alert drivers when they leave the travel lane. Centerline rumble strips reduce head-on collisions and cross-over crashes; shoulder rumble strips reduce
run-off-the-road crashes and warn drivers when they have drifted from their lane. SPT is the contractor for this $887,235 project.

Proposed Work Schedule
- Work is scheduled to begin May 4, 2020. Construction will start at the Utah border in Montrose County.
- Crews will install centerline rumble strips and restripe existing center lines along sections of CO 97 from milepost (MP) 1 to 4; CO 90 from MP 0 to 34; CO 141 from MP 0 to 16; CO 184 from MP 0 to 26; US Highway 550 from MP 33 to 46; CO 172 from MP 10 to 18; and CO 114 from MP 8 to 20.
- Construction will proceed in a southern and eastern direction along remaining highways. View interactive project map in Project Facts, above.
- The entire project duration from start to finish is estimated to be approximately one month and will be completed no later than June 1, 2020.
Normal working hours will be from 7:00 am to 5:00 pm Monday — Saturday; however construction on CO 141 and 114 will be performed 10:00 am to sunset to minimize impacts to Gunnison Sage-grouse and its habitat.
