The station consists of two side platforms situated under street level, with two mezzanines connecting to the surface at James Street and Yesler Way in Seattle's Pioneer Square neighborhood. It opened on September 15, 1990, and was used exclusively by buses until 2009. The tunnel and stations closed for almost two years, from 2005 to 2007, for renovation and modifications to accommodate light rail trains. Link light rail service to Pioneer Square station began on July 18, 2009, and bus service ended on March 23, 2019. Trains serve the station twenty hours a day on most days at a frequency of six minutes during peak periods and 12–20 minutes at other times. In early 2020, Pioneer Square station served as a transfer point between trains with a temporary center platform as part of construction for the 2 Line.
Much of the non-government and non-historic land use around Pioneer Square station is for high-rise offices and multi-family housing. Within a 1⁄2-mile (0.8 km) radius of the station is an estimated population of 12,866 people, and approximately 69,795 jobs.[7] Nearby office towers include Smith Tower,[4] the Columbia Center, and Wells Fargo Center.[8] The corporate headquarters of logging company Weyerhaeuser was moved from Federal Way to Occidental Park near Pioneer Square station in 2016; the company cited transit access as one of its main reasons to choose the neighborhood.[9][10]
History
Earlier proposals
Pioneer Square was developed as Seattle's initial settlement in the 1850s and continued to serve as the city's downtown into the early 20th century.[11] In 1911, civil engineer Virgil Bogue presented a comprehensive plan for the city of Seattle, including a rapid transit system centered around a "trunk" subway under 3rd Avenue, passing through Pioneer Square and the growing commercial and retail district to the north.[12][13] The plan was rejected by voters on March 5, 1912,[14] and the 3rd Avenue subway was unsuccessfully proposed twice in the 1920s.[15][16]
In the late 1960s, the Forward Thrust Committee put forward a ballot measure to fund a rapid transit system in the Seattle metropolitan area, including a downtown subway under 3rd Avenue with a station between Cherry and James streets.[17][18] The ballot measure, requiring a supermajority to support bonding to augment $385 million in local funding with $765 million from the Urban Mass Transportation Administration, failed to reach the 60 percent threshold in 1968 and again during a second vote in 1970.[19][20] The failure of the Forward Thrust ballot measures led to the creation of Metro Transit in 1972, operating bus service across King County.[21]
Bus tunnel

Metro Transit began planning a bus tunnel through downtown Seattle in the 1970s, to be eventually converted to use by light rail trains. Metro approved the construction of a bus tunnel under 3rd Avenue in 1983,[22] and chose to site one of the tunnel's five stations near the King County Courthouse at 3rd Avenue and James Street.[23][24] The station was to be completed by late 1989 and use brick, stone, and tile to complement the design of nearby Pioneer Square.[25][26]
Metro awarded a $44.1 million contract to a joint venture of Atkinson and Dillingham companies to build the tunnel's 3rd Avenue segment as well as Pioneer Square station. Excavation of the station from street level began in March 1987,[27] and the project's twin tunnel boring machines reached James Street from Union Station in September.[28] In June 1987, Atkinson-Dillingham and Metro were fined $80,000 after drilling at the station severed three electric power transmission lines, causing a day-long power outage in downtown Seattle, affecting the City Hall and Public Safety Building.[29] Work in the tunnel station was also blamed for shaking in the City Hall and Public Safety Building, requiring monitoring equipment to be set up by Metro.[30]

By late 1988, the Pioneer Square station structure was 70 percent complete, and work had begun on the station's entrances and the vaulted ceiling.[31] The station was the subject of two controversies during its construction over the use of South African materials in its construction, as the country was then under a Metro boycott for its Apartheid policies. In late 1987, Atkinson-Dillingham was forced to remove steel beams used for temporary shoring at the station box after unknowingly sourcing it from South Africa.[32] Metro later acquired South African black granite to be used in the station's platform and mezzanine, which was discovered and returned; the incident resulted in the resignation of Metro's executive director, amid outcry from African American leaders.[33][34]
Tunnel construction was completed in June 1990, and was celebrated with a soft opening of Pioneer Square station and the re-opening of Prefontaine Park.[35] During preparation for the resurfacing of 3rd Avenue above the new tunnel station, workers discovered an 11-foot (3.4 m) cable carflywheel that had been buried after service on the Yesler Way line ceased in 1940.[36] The flywheel was later restored and placed in the south mezzanine of Pioneer Square station.[4] Bus service in the Downtown Seattle Transit Tunnel began on September 15, 1990, with several Metro bus routes moved into the tunnel from surface streets.[37] At the time of its opening, Pioneer Square station had the longest and steepest escalator west of the Mississippi River.[38] All service on routes using the tunnel was operated by dual-mode buses, which operated as diesel buses outside the tunnel and electrically, as trolleybuses, when inside the tunnel. During its early months, Pioneer Square and other stations were affected by serious water leaks, which splashed water onto walkways during the tunnel's first winter in operation.[39] The leaks were later fixed by Metro contractors, but remained visible in the form of rust stains on the station ceiling.[40][41]
Light rail
A third platform was installed at Pioneer Square for use during a light rail construction project in early 2020
In the early 1990s, a regional transit authority (RTA) was formed to plan and construct a light rail system for the Seattle area. After an unsuccessful attempt in 1995, regional voters passed a $3.9 billion plan to build light rail under the RTA in 1996.[42] The downtown transit tunnel had already been planned for eventual light rail use and was built with tracks that would be incorporated into the initial system.[43][44] The RTA, later renamed Sound Transit, approved the tunnel as part of the route of its initial light rail line in 1999.[45] Ownership of the tunnel, including its stations, was transferred to Sound Transit in 2000 but returned two years later to King County Metro under a joint-operations agreement.[46][47]
The Public Safety Building, located at the station's northeast entrance, was demolished in 2005. In its place, the city planned to build Seattle Civic Square, a mixed-use skyscraper, with a new entrance to the station.[48] As of 2016[update], the project is on hold and a temporary entrance has been erected at street level.[49]
The downtown transit tunnel closed on September 23, 2005, for a two-year, $82.7 million renovation to accommodate light rail vehicles. The renovation included the installation of new rails, a lowered roadbed at stations for level boarding, new signalling systems and emergency ventilation.[50][51] The tunnel reopened on September 24, 2007,[52] and Link light rail service began on July 18, 2009, from Westlake station to Tukwila International Boulevard station.[53][54]
Bus service within the downtown transit tunnel ended on March 23, 2019, due to the expansion of the Washington State Convention Center at the site of Convention Place station, which includes demolition of the north portal. The tunnel became exclusively served by light rail trains, while the remaining seven bus routes were relocated to surface streets and nearby bus stops on 2nd, 3rd, 4th, and 5th avenues.[55][56]
As part of East Link Extension construction for the 2 Line in early 2020, Pioneer Square station was outfitted with a temporary third platform in the center to allow passengers on terminating single-tracked trains to transfer.[57] The temporary platform was installed during two weekend closures in October 2019 and was used from January to March 2020.[58][59] Ownership of the tunnel and Pioneer Square station was transferred to Sound Transit in 2022.[60] A 2022 proposal for the Ballard Link Extension includes a new transfer station one block east of Pioneer Square to be used by trains on the realigned 1 Line in lieu of a transfer at International District/Chinatown station.[61]
Laura Sindell's ceramic mural, located in the south mezzanine entrance
Pioneer Square station consists of two underground side platforms used to load passengers onto trains and buses, a mezzanine level, and several surface entrances.[62] The station has two mezzanines on its north and south ends, with the center portion opened to the platform below; all levels are connected by a series of eight escalators, six elevators, and stairs.[63] The north mezzanine under James Street has two entrances: a pair of escalators and a stairway to 3rd Avenue at the future site of Seattle Civic Square;[64] and a single escalator and stairway to 2nd Avenue in the Lyon Building. The south mezzanine has a single entrance to Prefontaine Park at Yesler Way between 2nd and 3rd avenues, under a large pergola similar to an older streetcar shelter in Pioneer Square. The Prefontaine Park entrance houses an 8-by-50-foot (2.4 by 15.2 m) ceramicmural created by artist Laura Sindell, depicting people-like figures, a 19th-century quilt pattern, a Coast Salish basket design, and a dugout canoe.[65][66] Several of the station's entrances feature inscribed quotes from historic Seattle figures, including Chief Seattle, "Doc" Maynard, and Arthur A. Denny. The south mezzanine also has a large flywheel once used by the Yesler Way cable car and later buried in a vault until its discovery during tunnel construction.[4][36] Pioneer Square station is approximately 570 feet (170 m) long, 70 feet (21 m) wide, and 60 to 70 feet (18 to 21 m) deep.[67]
Designed by architect Jerry McDevitt, the station has an arched vault ceiling that is meant to reflect the area's historic buildings.[62][68] The platform level also makes extensive use of red and gray granite, matching the King County Courthouse and former Public Safety Building,[65] and railings that resemble hitching posts and hanging lamps.[4][69] Artists Kate Ericson and Mel Ziegler created the station's two "artifact clocks", which hang from the mezzanine at each end of the platform. The north mezzanine clock uses materials from modern construction, including granite, steel beams, and electrical wires; the south mezzanine clock incorporates artifacts found during construction dating back to the city's early history, including cobblestones, brick, and cast-iron pipes.[62][70] Both clocks use various tools used during construction, including a handsaw and industrial-size tape measure, for the clock face's numerals.[65]
Pioneer Square station is part of the Downtown Seattle Transit Tunnel, which is served by the 1 Line of Sound Transit's Link light rail network. It runs from Northgate to the University of Washington campus, Downtown Seattle, the Rainier Valley, and Seattle–Tacoma International Airport. Pioneer Square is the eleventh northbound station from Angle Lake and seventh southbound station from Northgate, situated between International District/Chinatown and University Street stations. Light rail trains serve Pioneer Square twenty hours a day on weekdays and Saturdays, from 5:00 am to 1:00 am, and eighteen hours on Sundays, from 6:00 am to 12:00 am; during regular weekday service, trains operate roughly every eight to ten minutes during rush hour and midday operation, respectively, with longer headways of fifteen minutes in the early morning and twenty minutes at night. During weekends, trains arrive at Pioneer Square station every ten minutes during midday hours and every fifteen minutes during mornings and evenings. The station is approximately 33 minutes from SeaTac/Airport station and five minutes from Westlake station.[72] In 2019, an average of 4,677 passengers boarded Link trains at Pioneer Square station on weekdays.[1]
From 2009 to 2019, several bus routes also ran in the tunnel alongside Link light rail. The final set of bus routes in the tunnel were divided into three bays by their outbound direction: Bay A was served by three routes heading north toward Northgate and the University District and east towards Kirkland (routes 41, 74, and 255); Bay C was served by three routes heading south through the SODO Busway toward Kent and Renton (routes 101, 102, and 150); and Bay D was served by one route heading east via Interstate 90 to Bellevue (Sound Transit Express route 550).[75] The bus routes were relocated in March 2019 to new stops on 2nd, 3rd, and 5th avenues to serve Pioneer Square and the surrounding area.[79][80]
