The Pioneer Square Station is a Downtown Seattle Transit Tunnel station located in Pioneer Square, served by Sound Transit Central Link light rail trains, Sound Transit buses and King County Metro buses. It is completely underground, with entrances in the former Public Safety and Lyon buildings and next to Prefontaine Place on 3rd Avenue. 3,300 daily Link light rail boardings are predicted for the year 2020.
Originally constructed as a bus-only station by Metro and opened in 1990 for use by dual-mode buses/trolleybuses, it was rebuilt in 2005-2007 by Sound Transit for eventual use by light rail trains. Light rail service at this station started on July 18, 2009, with the opening of the Link system.
There are entrances to the underground station at 3rd & James and 3rd & Cherry. There is also an accessible entrance along 3rd between Cherry and James.
