Long-term closure of IBM Drive at CO 119 starts Oct. 1

Travel Advisory

September 27, 2024 - Northeastern Colorado - Road closure required to build new CO 119 and CO 52 intersection

Boulder County - The Colorado Department of Transportation and Contractor, Kraemer North America, will close IBM Drive, from Colorado Highway 119 to IBM East Loop Road, as part of the CO 119 Safety, Mobility and Bikeway Improvements Project on Tuesday, Oct. 1.

Once closed, it will remain closed to all modes of transportation and travel for the duration of the closure–until the end of 2025.

For alternate access to the business park near IBM Drive, travelers should follow posted detour signs. Continue traveling southwest on CO 119 and exit at 63rd Street, head north on 63rd Street, turn east to Monarch Road and into the business parking lot.

This closure is required for crews to begin building the new CO 119 and the new CO 119 and Colorado Highway 52 intersection. Schedule can vary based on conditions.

What is the CO 119 Safety, Mobility and Bikeway Improvements Project?

By the year 2040, the Diagonal Highway between Boulder and Longmont is expected to see a 25 percent increase in vehicular traffic. Increased traffic can result in more congestion, delay, tailpipe emissions and potentially more crashes.

The CO 119 Safety, Mobility and Bikeway Project is constructing safety, mobility and bikeway improvements to make traveling through the corridor safer for all modes and transit travel faster and more reliable. The project is designed to integrate with other active multimodal projects on the corridor to ensure community members can safely and reliably travel throughout the corridor using their mode(s) of choice.

This project will:

  • Improve safety in the whole corridor.
  • Maximize the number of people able to move through the corridor.
  • Maximize intersection operational efficiency.
  • Improve transit travel times and increase ridership.
  • Maximize corridor-wide operational efficiency.
  • Increase opportunities for bicycle commuting and connectivity to the bicycle and pedestrian network.

Specific corridor improvements include:

  • New signage, striping and improved signal timing at all pedestrian crossings at signalized intersections.
  • Signal timing adjustments at key intersections (Jay Road, 63rd Street, Colorado Highway 52, Niwot Road and Airport Road).
  • Physically reconfiguring the CO 52 intersection to improve safety and to accommodate new Bus Rapid Transit stations and Boulder County’s Commuter Bikeway between the northbound and southbound travel lanes.
  • Changing access at Airport Road and CO 119 to reduce crashes and to improve safety and traffic flow.

During construction, CO 119 will largely remain configured as it currently operates, with various lane shifts and closures. Additional notice information will be provided prior to any major closures or detour routes throughout the project duration. In addition, lane and shoulder widths will be minimized. The speed limit will be reduced. Please pay attention and follow posted speed limit signs. Kraemer North America is the General Contractor for this project.

Know Before You Go

Travelers are urged to “know before you go.” Gather information about weather forecasts and anticipated travel impacts and current road conditions prior to hitting the road. CDOT resources include:

Remember: Slow For The Cone Zone

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!
