Final September 2026 Service Changes

RTD’s September 2026 Service Changes will take effect Sunday, September 27. The changes are designed to strengthen the transit network by improving reliability, restoring and enhancing service, and better aligning resources with customer needs. The changes also include new and expanded service, frequency and schedule adjustments, seasonal service updates, and other improvements across the system.

Highlights include ongoing accommodation of the Downtown Rail Reconstruction Project, the introduction of new SkyRide service connecting Longmont and Denver International Airport, initial service changes to support East Colfax Bus Rapid Transit, improvements to select bus and rail services, and adjustments that help maintain and optimize the transit network. The changes below reflect customer and stakeholder feedback, ridership and operational trends, and ongoing efforts to provide a more reliable, responsive, and resilient transit system.

Customer feedback is essential to shaping RTD’s service changes. We sincerely appreciate our customers for sharing their feedback in whatever way works best for them, whether it's completing a survey, joining a public meeting, speaking with a service planner, sending an email, or simply stopping by to chat at a community event. Thank you for your participation and feedback as we strive to make lives better through connections.

Final September 2026 Service Changes

In addition to the routes listed below, the following changes will also take effect on Sunday, September 27th.

Route 0B - South Broadway - Schedule Timing

Service Change

Minor changes to weekday, Saturday and Sunday/Holiday schedules.

Service Change Reason

Schedule changes will eliminate overlap with Route 0L.

Survey Results

Since this change was not included in the proposed September Service Changes, no survey data was collected.

Route 23 - West 20th Avenue - Route Adjustment, Schedule Timing

Service Change

Route 20 will be split into Route 20 and Route 23, with Route 23 serving the western portion and Route 20 serving the eastern portion of the route.

Route 23 will operate between National Lab of the Rockies and Union Station.

Customers traveling between the western and eastern portions of the former Route 20 will need to transfer between Routes 23 and 20.

Service Change Reason

Breaking the route 20 into eastern and western separate routes was a recommendation of the System Optimization Plan, which will improve reliability and schedule adherance. However, the route 23 continues into downtown, which was not recommended in the SOP, in order to maintain connectivity between Lakewood and Edgewater to downtown Denver.

Survey Results

Out of 26 respondents, 57% reported a positive impact from the change, 8% indicated it had no impact, and 34% perceived the change negatively.
