2. New SLU connections across SR-520


Sound Transit continually monitors the performance of the ST Express system and identifies routes or trips that do not meet standards and are candidates for change. Currently, two SR-520 routes, Routes 540 and 541, are among the lowest performing of all ST Express routes.


As part of our continued coordination with King County Metro and their proposed North Eastside Mobility Plan (NEMP) and to more effectively use taxpayer resources, Sound Transit will be considering the following changes to ST Express SR-520 service:

  • Consolidate ST Express Routes 540 and 541 into new Route 544, serving Overlake, South Kirkland, SR 520 and South Lake Union.
  • On morning eastbound trips, Route 544 would serve Capitol Hill at Bellevue Ave & Olive Way. Route 545 would no longer stop on Capitol Hill.

Note: These proposed service changes to ST Express service are contingent upon King County Metro changing Route 255 to serve University of Washington Station.
