Proposed September 2026 Service Changes
RTD’s Proposed September Service Changes are designed to further enhance and strengthen RTD’s transit network by refining service, improving reliability, and better aligning resources with customer needs.
As part of the September 2026 Service Change, RTD is advancing a coordinated set of transit service enhancements designed to strengthen reliability, restore key frequencies, and improve access to major destinations across the system. These proposed changes reflect observed utilization trends, operational performance, and lessons learned during recent reconstruction activities, while maintaining flexibility for future evaluation and adjustment. Several of the recommended enhancements are supported by Clean Transit Enterprise (CTE) grant funding and are intended to restore and expand service consistent with the System Optimization Plan (SOP), noting that final CTE allocations are still in development.
You can view all the proposed changes below and learn more by watching our presentation in English or Spanish.
Customer feedback on the Proposed September Service Changes was collected through July 8, and we thank all who participated!
Final service changes will be published once approved by the RTD Board of Directors and will take effect on Sunday, September 27.

Reason
Maintains connectivity between Lakewood and Edgewater to downtown Denver.

Reason
Requested by policymakers, stakeholders and customers, service will provide connections from Longmont to Denver Airport via the Lafayette Park-n-Ride
Survey Results
Out of 257 respondents, 98% reported a positive impact from the change, 1% indicated it had no impact, and 1% perceived the change negatively.
BMFX - Broomfield FlexRide
Service Increase
Proposed Change
Extend weekday service to 9 p.m., with an extra vehicle added during a.m. and p.m. peaks. Add a second vehicle during Saturday peak hours; and implement Sunday service from 9 a.m. to 4 p.m.
Reason
The City and County of Broomfield requested additional service, which can be supported through available grant funding.
Survey Results
Out of 17 respondents, 83% reported a positive impact from the change, 12% indicated it had no impact, and 6% perceived the change negatively.

Dashboard: Routes and Lines
A
Union Station – Denver Airport
- Schedule Timing
- Service Reduction
- Seasonal Adjustment
Change
Schedule adjustments, modifying early morning and evening service frequencies as follows: 3 a.m. to 6 a.m.: 30-minute frequency 6:15 a.m. to 7:30 p.m.: 15-minute frequency 7:30 p.m. to end of service: 30-minute frequency (as compared to current schedule, which transitions to 30-minute frequency beginning with the 6:30 p.m. departure from Union Station and the 7:27 p.m. departure from Denver Airport). These changes to schedule timing will also result in the loss of (2) daily morning trips, the 5:45 a.m. eastbound and the 6:42 a.m. westbound.
Reason
Adjusting the span of 15-minute service better aligns frequency with customer demand by providing more frequent service later into the evening. Schedule changes also create more consistent departure times during periods of 30-minute service, making the schedule easier to understand while improving operational efficiency and better aligning service with contractual requirements.
Survey Results
Out of 152 respondents, 40% reported a positive impact from the change, 28% indicated it had no impact, and 32% perceived the change negatively.

- Service Reduction
Change
The D Line, which is currently not operating, will be permanently discontinued once the Downtown Rail Reconstruction Project is complete.

Service beyond I-25•Broadway may be considered based on ridership demand, available funding, and operational considerations.
Reason
Upon completion of the Downtown Rail Reconstruction Project, reinstating and enhancing L Line service would restore rail service along the corridor, provide additional connections within the light rail network, and support travel options for customers previously served by the D Line through the Downtown Loop.
