The Service Network Map

This map is not a service change proposal, but a long range vision developed for the purpose of generating representative costs and benefits. Final decisions on project elements or alignments will require additional outreach, analysis, engineering and appropriate council or board approval. Elements on this map should not be construed as a commitment that all representative features will be included in the final projects.

Unchanged routes retain existing route numbers. Four-digit route numbers are placeholders for future routes. 1000s are frequent routes (red); 2000s are express routes (green); 3000s are local routes (yellow). Transit alignments are approximate and do not represent final decisions. Sound Transit services represented here have been developed to assist the Sound Transit Board as it develops an ST3 system plan for voter consideration.
