Boulder’s Public Transit System

Boulder maintains an extensive public transit system focused on sustainability, accessibility, and rider experience.

Complementing the RTD regional routes is the innovative local transit network. The free HOP bus loops between downtown Boulder and University Hill, while the DASH and SKIP provide neighborhood shuttle services. These local routes offer bike racks, wheelchair lifts, and real-time bus tracking through the Transit app.

Boulder Transit promotes sustainability through initiatives like the Zero Fare for Better Air program, which eliminates fares during August to reduce car trips and emissions. This boosted 2021 ridership by over 25% during the month. The program’s success highlights Boulder residents’ avid support for green transportation alternatives.

Sustainable Transit Initiatives

With the climate crisis intensifying, Boulder continues to lead in sustainable transportation planning and policies. The city’s Transportation Master Plan sets ambitious goals to mitigate transportation emissions, which account for 16% of Boulder’s carbon footprint.

Strategies include expanding zero-fare transit access, electrifying buses, integrating multimodal hubs across the city to promote walkability, and connecting more residents with frequent transit services. Boulder also emphasizes equity, developing routes to serve all neighborhoods regardless of income levels. Grants from the state’s Multimodal Transportation and Mitigation Options Fund will support several of these proposed projects.
