Friday Roundtable: 2025 Ridership Data

Key Takeaways

• Route 223 records ~1,000 weekday boardings, highest among new routes.
• Federal Way Link Extension opened Dec 2025, cutting A Line boardings by 40%.
• South King County ridership shifts ahead of Fall 2026 service restructure.
• Eastside routes see dramatic changes after March 2026 2 Line launch.
• Dashboard now includes 2025 data for Metro and Sound Transit routes.

Pulse Analysis

Transit agencies rely on granular ridership metrics to fine‑tune service levels, allocate resources, and justify capital investments. The updated Seattle Transit Ridership dashboard aggregates daily boardings across Metro and Sound Transit corridors, offering a unified view that was previously fragmented. By integrating 2025 figures, planners can compare pre‑ and post‑expansion performance, identify emerging demand clusters, and calibrate frequency adjustments with greater precision. This level of transparency also supports public accountability, allowing riders and policymakers to track the impact of recent funding measures.

The most striking story in the new data set is the rapid adoption of the Federal Way Link Extension, which opened in December 2025. Within months, the A Line’s outbound boardings at the 200th St stop fell from roughly 500 to 300 weekday riders, a 40% decline that underscores a modal shift toward the faster, higher‑capacity Link service. Meanwhile, the east‑side’s Route 223 quickly reached about 1,000 weekday passengers, confirming the demand for the newly introduced east‑side connections. These patterns illustrate how strategic infrastructure can cannibalize existing bus routes while simultaneously generating new ridership corridors.

Looking ahead, the upcoming Fall 2026 service restructure—dubbed South and East Link Connections—will likely amplify these dynamics. As Metro and Sound Transit roll out additional route realignments, ridership will continue to migrate toward high‑frequency, rail‑centric corridors, prompting a reassessment of bus‑only services. Stakeholders should monitor the dashboard closely to gauge the effectiveness of these changes, inform future funding requests, and ensure that the evolving network meets the region’s growing mobility needs.
