Tacoma Link Expansion

Tacoma Link light rail passes Union Station in Tacoma

The 1.6-mile Tacoma Link light rail line currently serves six stations between the Theater District and Tacoma Dome Station. Trains run every 12 minutes during the day and served one million riders in 2012. Voters approved Sound Transit 2 in 2008, which included funding for a partnership to explore options for expanding Tacoma Link.

This project will identify and study alternative travel corridors for expanding the Tacoma Link system and produce a project financing plan that identifies committed and potential funding sources. Sound Transit, in cooperation with the City of Tacoma and Pierce Transit, engaged the community to help identify a range of alternatives, study these alternatives  and determine a preferred alternative for expansion. Sound Transit will continue to engage the community throughout conceptual design and environmental review for the selected alignment.
