Jay Road serves as an important connector between Boulder and Gunbarrel and sees some of the highest vehicle and bicycle volumes of any county road. Unfortunately, it also has some of the highest numbers of bicycle-vehicle crashes of any unincorporated county road. Between 2006 and 2018, two-thirds of bicycle-vehicle crashes on Jay Road are the result of conflicts between turning vehicles and cyclists traveling straight.
Community Cycles advocated for improvements along Jay Road, including a buffered bike lane, green paint at intersections, pedestrian islands, lane narrowing and flexible delineator posts with the goal of lowering speeds and calming traffic on Jay. The County has moved forward with improvements such as repainting, narrowing the existing travel lanes by one foot to accommodate the buffer, and installing a signalized crossing at the LOBO Trail crossing at the Cottonwood Trailhead and Jay Road.
