LINK LIGHT RAIL
- Extends the Lynnwood Link extension that is on track for 2023 completion northward from Lynnwood to downtown Everett via I-5, SW Everett Industrial Center and Evergreen Way, with up to eight (six plus two provisional) new stations. Riders could travel from Everett to downtown Seattle (Westlake Station) in 59 minutes. Trains would run every six minutes in peak commute hours, with more frequent service south of Mariner park-and-ride.
- New light rail stations would serve the areas of West Alderwood Mall, Ash Way, Mariner, SR 99 (provisional), Southwest Everett Industrial Center, Evergreen, Northern Evergreen (provisional) and the area of the existing Everett Station, with parking investments at Mariner and Everett Stations.
- Funds a study of a potential future extension of light rail from downtown Everett to Everett Community College.
- Extends the East Link light rail line that is on track for 2023 completion, from Redmond’s Overlake area to a new station with parking serving Southeast Redmond, continuing to downtown Redmond. Riders could travel from Seattle to downtown Redmond in 42 minutes. Trains would run every six minutes in peak commute hours.
- Establishes a new Eastside light rail line, reaching eastward from the southern edge of downtown Bellevue — with a connection via East Link to Seattle or Redmond and I-405 BRT — to Eastgate and Issaquah. Up to four new Eastside light rail stations would serve the areas of Richards Road, Eastgate near Bellevue College, Lakemont (provisional station) and Central Issaquah, with a parking facility in Central Issaquah. Riders could travel from downtown Bellevue to Central Issaquah in 17 minutes. Trains would run every six minutes in peak commute hours.
- Funds a study between Bothell and Bellevue to complete environmental review for a potential future high capacity transit line, while providing Kirkland-area residents with expanded near-term transit connections via access to I-405 BRT in Central Kirkland.
- Extends grade-separated light rail service from downtown Seattle to West Seattle with new stations serving the stadiums, SODO, Delridge, Avalon and Alaska Junction areas. Riders could travel from downtown Seattle (Westlake Station) to the West Seattle Junction in 17 minutes. Trains would run every six minutes in peak commute hours.
- Extends light rail to Ballard with a new tunnel through downtown Seattle and South Lake Union, with stations in the areas of Midtown, Denny, South Lake Union, Seattle Center, Smith Cove and Interbay. Riders could travel from downtown Seattle (Westlake Station) to Ballard in 12 minutes. Trains would run every six minutes in peak commute hours.
- Adds new stations to the existing Link line at Graham Street and the Boeing Access Road.
- Funds studies of potential future high capacity transit investments to link West Seattle with Burien. An additional study of high capacity transit across northern Lake Washington would include connections along SR 520, SR 522, Ballard to Kirkland via University of Washington, Sand Point to Kirkland and on to Redmond and/or Bellevue.
- Extends grade-separated light rail in South King County from Kent/Des Moines that is on track for 2023 completion to Federal Way, with three stations in Federal Way, including parking structures at South 272nd and South Federal Way and access to the existing Federal Way Transit Center. Light rail then continues farther south through Pierce County connecting with the major transit hub at the Tacoma Dome, including a new station in East Tacoma and a new station with parking in Fife.
- Riders will be able to travel between the Tacoma Dome and the Federal Way Transit Center in 19 minutes, and from the Federal Way Transit Center to downtown Seattle (Westlake Station) in 49 minutes. Trains would run every six minutes in peak commute hours.
- Further expands Tacoma Link extension to reach Tacoma Community College, with six stations. The project would follow the current Tacoma Link expansion project to MLK Avenue that is on track to start construction in 2018.
SOUNDER COMMUTER RAIL
Sounder North Commuter Rail
- Constructs new parking and other access improvements in Edmonds and Mukilteo as early deliverables.
Sounder South Commuter Rail
- Analysis and partner coordination prior to the adoption of a final ST3 measure will determine the most effective south corridor capital investments to serve more riders, including potential lengthening platforms for longer trains, and/or potential investments in tandem with BNSF to enable running more trains on an extended schedule.
- Extends Sounder South service from Lakewood to a new station at DuPont, with a station and parking facility at Tillicum, to help serve Joint Base Lewis/McChord.
- Increases parking and/or establishes other access improvements in the south corridor at Tukwila, Kent, Auburn, Sumner, Puyallup, Tacoma, South Tacoma, and Lakewood stations.
- Funds a study to explore future South Sounder connections to Orting.
BUS RAPID TRANSIT (BRT)
East, North and South Corridors
- Establishes BRT service from Lynnwood to Tukwila International Boulevard light rail station on I-405 and SR 518, continuing to the Burien Transit Center in new bus-only lanes.
- New parking garages are planned at Kingsgate/Totem Lake and South Renton.
- A new freeway station is included at NE 85th Street in Central Kirkland and a new transit center in South Renton. The BRT service will connect with existing freeway stops and transit centers in Lynnwood, Canyon Park, UW Bothell, Brickyard, Kingsgate/Totem Lake, Downtown Bellevue, Tukwila International Boulevard Station and Burien.
- Access by Kirkland residents to the system would be facilitated by the new Central Kirkland BRT freeway station along I-405. New bus-only lanes on NE 85th Street between I-405 and NE 6th would improve bus speed on NE 85th Street to the Kirkland Transit Center.
- BRT service on SR 522 and NE 145th would connect riders with the future Link light rail station on I-5 as well as planned I-405 BRT service, substantially improving transit options for residents of the Lake Forest Park, Kenmore, Bothell and Woodinville areas. Additional parking would be constructed at Lake Forest Park, Kenmore and Bothell.
- Sound Transit’s regional bus system, which led the nation in number of Commuter Bus boardings for 2015, will build ridership in key long distance corridors. ST3 would fund approximately 600,000 annual hours to continue providing interim express bus service in future HCT corridors.
INTEGRATING WITH TRANSIT PARTNERS
Sound Transit is coordinating its service planning with local transit agencies to extend the reach and frequency of transit services throughout the region. Each new rail station in the ST3 draft plan provides bus-rail and BRT transfer facilities to make customer connections easy and convenient.
PROVIDING MULTI-MODAL ACCESS
The ST3 Draft Plan enhances Sound Transit’s customer access to stations. It includes funding at each station for improved access to the system, tailored to the geography, land use and population and employment density surrounding each rail station. Sound Transit is committed to providing multi-modal access to the regional transit system: non-motorized (bike and walking), transit connections with local partner services, pick-up & drop-off and parking where appropriate. The plan includes a funding program for these improvements.
ENCOURAGING TRANSIT ORIENTED DEVELOPMENT AND AFFORDABLE HOUSING
Transit does more than move people from place to place. Well-coordinated transit and zoning supports transit-oriented development (TOD), resulting in residential and commercial neighborhoods that are compact, efficient, diverse and walkable. The ST3 Draft Plan targets resources toward coordinated planning with cities and counties to promote development of affordable housing near stations.
OPERATIONS AND MAINTENANCE FACILITIES FOR BUS AND RAIL
The new bus and rail lines provided under ST3 will include new maintenance facilities located strategically around the region to ensure efficient system operations. During environmental review prior to final project decisions, Sound Transit will work with cities and counties to determine the most appropriate locations for these essential facilities.
The ST3 Draft Plan includes funds to develop new transit technologies to:
- improve rider information and fare payment;
- study impact of connected vehicle and driverless vehicle technologies;
- build partnerships with public and private mobility service providers such as bikeshare, carshare, rideshare, and shuttle services;
- increase data analysis and research to identify and solve barriers to transit use;
- develop transportation demand management strategies to increase system ridership.
PROTECTING THE ENVIRONMENT
Regionally, transportation is the largest source of the air pollution that causes global warming. Transit helps lower pollution by providing low carbon transportation alternatives, reducing the number of vehicles on the road and supporting community development that reinforces smart regional land use goals. Transit also strengthens our region’s public health by reducing the harmful pollutants that cause serious respiratory illnesses such as asthma.
