A press release from the City of Boulder announces the installation of new concrete “tall curbs” on some of the city’s protected bike lanes.

The press release explains, “The tall curbs will replace existing striped buffers and flexible white posts at strategic, prioritized locations on Baseline Road between 30th Street and Foothills Parkway. Ongoing work, along with community feedback, will help inform more significant improvements during the next phase of work beginning in 2024.”

Baseline Road is part of the Core Arterial Network (CAN), “a connected system of protected bicycle lanes, intersection enhancements, pedestrian facilities, and transit facility upgrades that will help reduce the potential for severe crashes and make it safer, more comfortable and more convenient for people to travel in Boulder.”

The project will be the first in the United States to use the more robust lane separators in an effort to improve safety for people on bikes. “Several of the tall curbs will showcase art from a local artist selected from the city’s mural roster.”
