Sound Transit Express routes will undergo changes starting August 29, with most routes expanding service and Route 515 being eliminated, according to a published update on August 20, 2026.
Residents relying on Route 515 will need to adjust to new service patterns, as the route's elimination is part of broader adjustments to improve connections and add stops serving Cathcart Park & Ride, as noted in a separate August 14, 2026 announcement.
The changes follow Community Transit's approval of a six-year Transit Development Plan on August 3, 2026, which includes expanded bus rapid transit and microtransit service.
