Proposed August 2025 Service Changes
Overview of the Proposed August 2025 Service Changes
RTD is proposing service changes to enhance reliability and connectivity, improve on-time performance, accommodate seasonal ridership, and account for RTD’s continued work on the Downtown Rail Reconstruction Project. These updates also support the agency’s System Optimization Plan, which aims to improve the overall transit experience for customers.
Customer feedback is essential to this process, and RTD offers multiple ways to participate. We encourage customers to share your thoughts by completing the digital survey, attending virtual public meetings and Ask a Service Planner sessions, emailing us, calling our team, or engaging with us at community events.
Feedback on the Proposed August 2025 Service Changes was collected through Thursday, June 19.
Once all customer feedback is reviewed and the RTD Board of Directors approves the final changes, they will take effect on Sunday, August 31.
Learn more about the proposed service changes by reviewing our presentation.
