Northeastern Colorado Pavement Marking & Rumble Strips

About the Project:

The Colorado Department of Transportation and Surface Preparation Technologies (SPT) will be completing pavement markings and constructing rumble strips along sections of six highways in northeastern Colorado.

The project will include pavement markings, edge line and center line rumble strips in seven counties: Boulder, Cheyenne, Larimer, Morgan, Washington, Weld and Yuma counties. A total of 176 miles of roadway will be improved along segments of the following highways: CO 7, CO 52, CO 93, and US 34, US 40, and US 287.

The project goal is to improve safety for drivers. 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.

Project Benefits

• 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.

Work Schedule:

• Work will last for 67 working days or approximately two months
• Working hours are approximately 30 minutes before sunrise to 30 minutes after sundown, Monday to Friday

Traffic Impacts:

Motorists can expect the following impacts during the period of construction:

• Lane closures in both directions of work
• Traffic shifts in work zone
• Reduced speeds through the work zone
• Narrowed lanes and reduced shoulders
• Width restrictions
• Signs will be posted to alert motorists to the closures and available detour routes
• Refer to COtrip.org for real-time travel conditions and road closures
