When Sound Transit opened the Crosslake Connection in March 2026, over 200,000 people went for a ride on the first day. Since then, the 2 Line has carried thousands of passengers between Seattle and the Eastside everyday. Many of these passengers are new transit riders who used to drive across Lake Washington, while others switched to the train from an ST Express bus. Sound Transit’s decision to wait until August to restructure its bus network gives us an opportunity to examine the Crosslake Connection’s impact on ST Express ridership.
The agency has not yet published Link ridership data for March and April, but it has shared ridership data for its ST Express bus routes. Unless otherwise stated, the analysis below is looking at the average weekday ridership in April 2026 (percentages are compared to March 2026).
Crosslake Routes
Route 542’s ridership has remained stable, just a 1% increase to 1,517 passengers. This route is significantly faster than the 2 Line (26 vs 53 minutes) between Redmond and UW, so it is unlikely that many passengers would have switched to the train. Last year, Route 542 had a nearly 18% increase in ridership between March and April.
Sound Transit’s other all-day route on SR-520, Route 545, was impacted by the Crosslake Connection opening. Ridership was down 13.5% in April. Despite this, the route’s 4,281 daily passengers still make it the busiest ST Express route. Route 545 saw a slight increase in ridership between March and April 2025.
