Transit Planning

While the county actively supports and funds some existing transit services, our main role is planning for future services. Our most recent efforts have been to create the Mountain Town Transit Feasibility Study.

In addition to actively participating in long range planning of transit routes, the county supports and encourages addressing first and final mile needs in order to make transit more accessible to a variety of users. RTD has recently completed some important studies on the subject:

Bus Passes – Boulder County EcoPass Subsidy

Boulder County companies and neighborhoods new to the EcoPass program that sign-up through the county are eligible for an introductory subsidy. The multi-year subsidy takes up to 60% off the first year and 30% off the second year of new contracts.

EcoPass is an annual transit pass purchased by an employer as a benefit for full-time employees. EcoPass provides unlimited rides on all local, regional, and light rail transit services operated by RTD.
