Sound Transit, the regional transit authority, provides weekday Sounder Commuter Rail service and daily express bus service to and from Seattle. Sound Transit has also established Tacoma Link light rail, a free electric streetcar line linking Tacoma Dome Station with the University of Washington, Tacoma, Tacoma's Museum District, and the Theater District. Expansion of the city's rail transit system is in planning stages by the city of Tacoma and Sound Transit. The line will be extended north along Commerce St/Stadium Way and then west along Division Ave. It will then turn south along Martin Luther King Jr. Way and end near South 19th Street.
