Union Station

Sound Transit's main offices are located in historic Union Station within the International and Pioneer Square districts in Downtown Seattle; it is not to be confused with King Street Station, which has the tall clock tower and serves as the Amtrak Rail Station and Sound Transit's Sounder commuter train station. Sound Transit also has offices at the 625 Union Station and the 5th and Jackson building.

Taking transit to Sound Transit

Bus routes serving Fourth or Fifth avenues at South Jackson Street and tunnel routes serving the International District/Chinatown Station in the Downtown Seattle Transit Tunnel will take you near Sound Transit's Union Station at 401 South Jackson Street. Link light rail also serves the International District Station. Leaving the transit tunnel via the north exit, walk west to the Union Station front entrance, located on South Jackson Street between Fourth and Fifth avenues.
