Centerline rumble strip project to begin on CO 6 on Tuesday

June 21, 2019 - Northeastern Colorado

PHILLIPS AND LOGAN COUNTIES — The Colorado Department of Transportation and Surface Preparation Technologies will be adding centerline rumble strips along 60 miles of Colorado Highway 6, starting at the Kansas border in Phillips County and proceeding westward to Sterling in Logan County.

The work will occur between June 25 and July 12. Work will not take place on weekends and July 3-5.

As part of CDOT’s Whole System-Whole Safety initiative, rumble strips are an effective measure for reducing roadway departure crashes. 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. According to the Federal Highway Administration, centerline rumble strips reduce fatal and injury crashes by 38% to 50% on rural two-lane roads and by 37% to 91% on urban two-lane roads.

Motorists can expect single-lane closures with delays from 5 to 10 minutes. No single lane closure will exceed two miles, but there may be multiple closures set up allowing the work convoy to continue while the previous closure is removed.


  • For the week of June 24: Short-duration single lane closures with delays from 5 – 10 minutes.

  • No construction will take place during the July 4th holiday from July 3 – 5, 2019.


The following tips are to help you stay safe while traveling through maintenance and construction work zones.

  • Do not speed in work zones. Obey the posted speed limits.

  • Stay Alert! Expect the unexpected.

  • Watch for workers. Drive with caution.

  • Don't change lanes unnecessarily.

  • Avoid using mobile devices such as phones while driving in work zones.

  • Turn on headlights so that workers and other drivers can see you.

  • Be especially alert at night while driving in work zones.

  • Expect delays, especially during peak travel times.

  • Allow ample space between you and the car in front of you.

  • Anticipate lane shifts and merge when directed to do so.

  • Be patient!


To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project takes a systematic statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.


CDOT has approximately 3,000 employees located throughout Colorado, and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated interregional express service. Governor Polis has charged CDOT to further build on the state’s intermodal mobility options.
