Jay Road intersections improvements project starts Monday

Safety project will require lane closures and shifts

Boulder County, Colo. - Boulder County Transportation will begin work on a pedestrian safety project at 8 a.m. on Monday, July 30 at three intersections along the western portions of Jay Road. The work will require reduced speeds, lane closures, and lane shifts, so expect travel delays between 8 a.m. and 4:30 p.m. until the project is complete, which is anticipated for the end of August.

Crews will install pedestrian crossings with refuge islands designed to help people safely cross one lane of Jay Road at a time, rather than having to find a gap in both east- and westbound traffic simultaneously. The new crossings will be installed along Jay Road at the 30th Street, St. Croix Street, and Lonetree Court intersections. Designs are available on the county website.

These improvements are a part of the larger Jay Road Safety Improvement Program that the county has planned. Jay Road serves as an important connector between Boulder and Gunbarrel and sees some of the highest bicycle volumes of any county road. Unfortunately, Jay also has some of the highest numbers of bicycle-vehicle crashes of any unincorporated county road and has recently experienced multiple serious bike/car crashes. As a part of the department’s ongoing efforts to increase safety for all travelers, the county will make the following improvements over the course of the next few months:

  • Striping a one-foot buffer to separate the travel lane from the bikable shoulder between 30th and 63rd streets
  • Applying green paint to the bikable shoulder at the intersections between 30th and 75th streets to highlight the possible location of bikes in the intersection
  • Installing rumble strips in the one-foot buffer to alert vehicle drivers when they veer out of their lane
  • Enhancing the bike and pedestrian crossing on Jay Road at Cottonwood Trail.

Jay Road Connections Project

In addition to the on-street improvements, the Transportation Department is also working with the City of Boulder to evaluate options for multi-use path connections between the Longmont-to-Boulder (LOBO) Trail at Spine Road the Cottonwood Trail at Jay Road. Trail users currently travel on the shoulder of Jay Road and a narrow bike lane on Spine Road to make this connection. An alternatives study will be completed this year. Final designs and funding will be identified after the study concludes. Learn more on the project website.
