Stadium station (Sound Transit)

Stadium station is a light rail station located in Seattle, Washington. It is situated between the SODO and International District/Chinatown stations on the 1 Line, part of Sound Transit's Link light rail system. The station consists of an at-grade island platform at the intersection of the SODO Busway and South Royal Brougham Way in the SODO neighborhood of Seattle, adjacent to Lumen Field and T-Mobile Park.

Stadium station was proposed in 1998 as part of the segment between the Downtown Seattle and Beacon Hill tunnels and subsequently deferred months later. It was reinstated in 2005 and construction of the station was completed in May 2006, several years before Link light rail service began on July 18, 2009. Trains serve the station twenty hours a day on most days; the headway between trains is six minutes during peak periods, with less frequent service at other times. Stadium station is also served by several Sound Transit Express and King County Metro buses that stop on the SODO Busway west of the platform, as well as the Seattle Greyhound station east of the platform.

Stadium station is situated at the intersection of the SODO Busway and Royal Brougham Way, under the ramps of Interstate 90, in the SODO neighborhood of Seattle. The station is adjacent to a King County Metro employee parking garage, which includes a pedestrian bridge over the platform to the Metro Ryerson Base, and the Seattle Greyhound bus station. The area surrounding Stadium station contains a mixture of light industrial zoning, primarily home to the manufacturing and warehousing industry employing over 13,000 workers, with some retail uses. Lumen Field and T-Mobile Park are located one block west of the station on the north and south sides of Royal Brougham Way, respectively. The light rail line is paralleled to the east by a mixed-use bicycle trail called the SODO Trail, which connects Stadium station to SODO station at South Lander Street. The Seattle Department of Transportation plans to extend the trail further south to Spokane Street, connecting it to a bike trail on the Spokane Street Viaduct, serving West Seattle.

Stadium station was not part of the initial Link light rail route approved in 1996, but was created as part of "Route C1" added to Central Link (now the 1 Line) by the Sound Transit Board in 1998. The routing included an at-grade section parallel to the SODO Busway and a tunnel under Beacon Hill, with stations at South Royal Brougham Way, South Lander Street and under Beacon Hill. While "Route C1" was selected as the final Central Link route in 1999, the station at South Royal Brougham Way was deferred, except for the construction of the platform and supports required for an infill station. The Sound Transit Board began studying the re-addition of a station at Royal Brougham Way in late 2004 and approved construction of the newly renamed Stadium station on January 13, 2005, using $3.7 million in surplus funds after bids for the construction of Link Light Rail were lower than budgeted.

Construction of Stadium station began with the laying of the first rails for Central Link, between Holgate and Lander streets, in August 2005. The station itself was built by Kiewit Pacific in less than a year, with opening ceremonies for Stadium and SODO stations held on May 30, 2006, celebrating the completion of the first two Central Link stations. Light rail testing on the 1.3-mile-long (2.1 km), at-grade SoDo segment began in March 2007, and ended in February 2008. Regular Link service from Seattle to Tukwila began on July 18, 2009, including the use of its pocket track to store extra trains serving a sellout friendly match between Seattle Sounders FC and Chelsea at Qwest Field.

The tracks crossing Royal Brougham Way sank by 3 inches (7.6 cm) due to ground settling and caused Link trains to be limited to 5 to 10 miles per hour (8.0 to 16.1 km/h). A track replacement began in August 2023 with trains on the 1 Line suspended for one weekend and single-tracking for several days afterward.

Stadium station consists of a single 400-foot-long (120 m), at-grade island platform accessible via an entrance at its north end, 130 feet (40 m) from South Royal Brougham Way. The platform itself has a width of 30 feet (9.1 m) to accommodate event crowds at Lumen Field (formerly CenturyLink Field) and T-Mobile Park (formerly Safeco Field). A pocket track located south of the station was built to store extra trains that are deployed after major sporting events.

The station's former pictogram was a depiction of the Olympic Torch, a representation of sporting culture. It was created by Christian French as part of the Stellar Connections series and its points represented nearby destinations, including the two stadiums. The pictogram series was retired in 2024 and replaced by station numbers.
