Sound Transit has been the popular name of Washington state's Central Puget Sound Regional Transit Authority since September 19, 1999. It was formed in 1996 by the Snohomish, King, and Pierce County Councils. It operates express bus, commuter rail, and light rail service in the region and constructs capital projects in support and expansion of those services.
Express Bus 
Sound Transit's express bus fleet is operated by local transit authorities Community Transit, King County Metro, and Pierce Transit. Its Regional Express Bus Service provides service to cities in all three counties, including Seattle, Redmond, Lynnwood, Mountlake Terrace, Issaquah, Lakewood, Bellevue, Auburn, Federal Way, Gig Harbor, Everett, Woodinville, and Tacoma.
Light Rail 
Current System 
Central Link runs between downtown Seattle and the Seattle-Tacoma International Airport. The initial section opened on July 18, 2009. The initial section runs through the Seattle's SoDo neighborhood, Beacon Hill, Rainier Valley, and portions of Tukwila. On December 19, 2009, the line was extended to the Seattle-Tacoma International Airport through Tukwila and SeaTac.
Under Construction 
University Link is a 3.5-mile (5.6 km) extension of the Link Light Rail system that is currently under construction. Construction on the line began on March 6, 2009, and is scheduled to be complete by 2016. The line will be underground for its entire route, and will connect downtown Seattle to the University of Washington via Capitol Hill. The cost of the extension is about $1.9 billion with half of the funding expected to come from a grant from the Federal Transit Administration.
Northgate Link Extension, an expansion of the Link Light Rail system from the University of Washington to Northgate, was approved by voters in November 2008. Although Sound Transit is currently developing the schedule for final design and construction, it had already finished the North Link's Final Environmental Impact Statement as of April 2006. The light rail line will link the University of Washington station to Brooklyn and Roosevelt, finally terminating at the Northgate Transit Center. The Northgate station would further provide access to the Northgate Mall and Lynnwood, via the Lynnwood Link Extension Project. This line is expected to be completed by 2021, following the completion of the University Link in 2016.
Sound Transit is also in the preliminary engineering phase for an 1.6-mile (2.6 km) extension from the SeaTac Airport Station to S. 200th Street in the City of SeaTac. The track is expected to be on an elevated guideway, following primarily 28th Avenue S. The line is expected to be completed sometime between 2015 to 2030, depending on funding.
The South Corridor HCT (High Capacity Transit) Project is expected to extend Link Light Rail from the planned S. 200th Street stop to Redondo/Star Lake, in a plan approved by the region's voters in November 2008. The project would add 4.8-mile (7.7 km) of track with stations at Highline Community College and Redondo/Star Lake. As the cost estimates have not yet been considered, the line is expected to be a primarily aerial line along SR 99. Final alignment and station designs are to be determined through the project level design and environmental review.
Similarly, the Lynnwood Link Extension Project is expected to extend the line from the future Nortgate stop to Lynnwood, via stations at NE 145th Street, NE 185th Street, and Montlake Terrace. However the Lynnwood Link Extension Project will rely primarily on federal grant money, for which Sound Transit still will need to complete the Alternative Analysis stage to qualify. Although this also means that the stations can be changed to reflect a number of scenarios, the Link Light Rail line is expected to be elevated.
Commuter rail 
Sounder Commuter Rail, a commuter rail service between Everett and Seattle, and between Seattle and Tacoma is operated by BNSF Railway on Sound Transit's behalf. There are currently 7 peak-direction and 2 reverse commute round-trips daily between Tacoma and Seattle and 4 peak-direction round trips between Everett and Seattle. Sound Transit will eventually run up to 18 daily round-trips from Tacoma once all trackwork is completed by BNSF Railway. They also plan on extending service to South Tacoma and Lakewood by 2012.
Current and soon-to-open stations are:
- Everett Station
- Edmonds Station
- Mukilteo Station
- King Street Station (Downtown Seattle)
- Tukwila Station
- Kent Station
- Auburn Station
- Sumner Station
- Puyallup Station
- Tacoma Dome Station
- South Tacoma (opening 2008 bus service/2012 commuter rail)
- Lakewood Station (opening 2008 bus service/2012 commuter rail).
Sound Transit 2 
2007 Vote 
Sound Transit 2 (ST2) was part of a joint ballot measure with the Regional Transportation Investment District entitled Roads and Transit, which was presented to Snohomish, King, and Pierce county voters on November 6, 2007. Sound Transit 2 would have made a number of mass transit related improvements. These changes included almost 50 miles (80 km) in new light rail lines, four new parking garages, two new Sounder stations, a streetcar line connecting First Hill, Capitol Hill, and the International District, a transit center in Bothell, and two expansion studies, one for studying rapid transit across the SR-520 floating bridge and the other studying the use of the Woodinville Subdivision between Renton and Woodinville. The ballot measure was defeated by voters.
2008 Vote 
The Sound Transit Board on July 24, 2008 voted to put a reduced Sound Transit 2 plan before voters. It passed by large margins on November 4, 2008. The financial plan for the measure shows $17.8 billion expenditure over 15 years, funded with a 5/10% rise in the regional general sales tax, which essentially doubles Sound Transit's revenue. Central Link Light Rail will be extended from the currently funded northern terminus at Husky Stadium north to Lynnwood. To the south, the tracks will continue from the current southern terminus at Sea-Tac Airport to the northern edge of Federal Way. The proposed East Link Light Rail will depart from Downtown Seattle and end in Overlake via Bellevue. A First Hill Connector (streetcar) is proposed from Central Link's Capitol Hill Station to the Jackson Street terminus of the former Waterfront Streetcar. In total, 36 new miles of two-way light rail track were approved by this measure.
Sounder Commuter Rail will receive longer and more frequent trains, for a 30% increase in service. Express Bus service will be immediately boosted (17% increase in service; 25 additional buses) and Washington State Route 520 will receive a Bus Rapid Transit line. A new commuter rail line is proposed to run from North Renton to Snohomish if additional funding beyond the Sound Transit taxes is secured.
