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 will be collected through July 8. We invite you to virtually attend our public meetings and Ask a Service Planner sessions, or share your feedback through the online survey. Customer feedback is important to RTD, and we thank you for participating however you can!

In addition to the routes listed below, the following routes also have proposed changes:
23 - West 20th Avenue
Route Adjustment, Schedule Timing
Proposed Change
It is proposed to split the existing Route 20 into Route 20 and Route 23, with Route 23 serving the western portion of Route 20 along 20th Ave., terminating at Union Station on the eastern end.
Reason
Maintains connectivity between Lakewood and Edgewater to downtown Denver.
AL - Denver International Airport to Longmont

Reason
Requested by policymakers, stakeholders and customers, service will provide connections from Longmont to Denver Airport via the Lafayette Park-n-Ride
BMFX - Broomfield FlexRide
Service Increase
Proposed Change

Reason

Dashboard: Routes and Lines
A
Union Station – Denver Airport
- Schedule Timing
- Service Reduction
Change
Schedule adjustments, modifying early morning and evening service frequencies as follows: 3 a.m. to 6 a.m.: 30-minute frequency 6:00 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. and 7 p.m. departures) The proposed change to schedule timing would result in the loss of (2) daily morning trips.
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.
C

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.
