Boulder's Community Transit Network

The Regional Transportation District (RTD) owns and operates a majority of Boulder's Community Transit Network, while Via Mobility Services operates the HOP route. The City of Boulder collaborates with both RTD and Via to plan and fund Boulder's local bus service.

The City of Boulder's vision for transit services focuses on developing and enhancing a complete transit system – a network of high-quality, frequent and convenient transit routes that connect local destinations and neighborhoods and regional destinations.

Paratransit services are on-demand, door-to-door transportation options that serve limited mobility riders who would have difficulty accessing and using standard bus service. Via Mobility Services and RTD both have paratransit options available to riders in Boulder.
