About these documents
As a regional transit authority, Sound Transit is required to prepare a six-year transit development plan and annual report. This document provides updated information to the Washington State Department of Transportation (WSDOT) on the development of the various transit components undertaken by Sound Transit - the Central Puget Sound Regional Transit Authority. WSDOT uses these documents to prepare an annual report for the Washington State Legislature summarizing the status of public transportation systems in the state.
