This case study by the Pedestrian and Bicycle Information Center (PBIC) was published online in 2009. Boulder has leveraged natural advantages with a significant commitment, well-designed plans, and resourceful follow-through to build a multimodal system and institutionalize the accommodation of bicycling and walking on many levels.
Boulder has over 100 miles of multiuse pathway with 74 underpasses allowing uninterrupted travel through much of town. Since 1989, the city has added to the system each year, on average, one mile of off-street path, half a mile of on-street bicycle lanes, and two underpasses. Ninety-five percent of major arterials have bicycle lanes or adjacent pathways. The off-street system is complemented by an additional 200 miles of dedicated on-street facilities that include bicycle lanes, signed routes and bikable shoulders. Bicycle paths and bicycle lanes have equal priority with the city's major street system for maintenance and snow control.
Boulder enjoys an 8.8 percent bicycle mode share, according to the 2006 American Community Survey, compared to a nationwide average of 0.5 percent.
