About

Today, Sound Transit and project partners celebrated the advent of heavy construction on the Sumner Parking Access Improvement project with a groundbreaking ceremony. When complete in 2026, the $49 million garage will serve Sounder S Line passengers and users of Sound Transit Express services. The 600-stall garage will provide approximately 500 net new parking spaces at the station. Currently, the existing parking at Sumner Station is routinely full very early in the morning.

“This project will provide increased access to Sounder, increased access to the region, and increased access to economic opportunity,” said Sound Transit Board Vice Chair and Fife Mayor Kim Roscoe. “As a Sound Transit Board Member from the South Sound and as a resident of Pierce County, it’s great to see our region’s investments in a robust transit system moving forward.”

“Given that Sumner was the first station to bounce back to 100% capacity after the pandemic, we know what a priority this project is for the community. Giving people more access to regional transit, and more options to travel, benefits us all,” said Sound Transit Interim CEO Goran Sparrman.

Previously, Sound Transit contributed $7.5 million for pedestrian, bicycle, lighting and ADA improvements to the Sumner station area. That work was performed by the city of Sumner.      

Sound Transit's Sounder S Line train service gives Pierce County residents a dependable, traffic-free commute to and from Seattle. The trip, with Wi-Fi, from Sumner Station to Seattle's King Street Station takes about 40 minutes. Weekend service is also offered for select major sporting events.

Sumner Station is also served by Sound Transit Express buses 578 and 596. Find S Line and ST Express schedule information here.

Sound Transit invites the public to learn more about potential options to restore some ST Express service in the South Corridor in 2025 and provide feedback on Phase One of the Service Plan.

As part of the service change in March 2024, Sound Transit reduced service on specific ST Express routes in the South Corridor due to industry-wide workforce challenges related to the pandemic that affected Sound Transit’s operating partner Pierce Transit.

The agency is committed to equitable restoration of ST Express service once staffing levels allow. We are working with operating partners to determine if we can restore the recent reductions subject to current operating constraints and staffing levels and are seeking public input about service restoration priorities.

However, if restoration is unachievable, Sound Transit will request Board authorization for continued service reductions.

In addition, Phase One of the 2025 Service Plan will include the opening of 2 Line service to Downtown Redmond. This extension will begin operating in the spring, with new stations at Marymoor Village and Downtown Redmond. Trains will run between Downtown Redmond and South Bellevue every 10 minutes between 5:30 a.m. and 9:30 p.m. seven days a week. ST Express Eastside bus service will not change in 2025.

The public can learn about the 2025 Service Plan – Phase One at soundtransit.org/2025serviceplan.

The website includes an online survey for visitors to provide feedback. Both the website and survey are also available in Spanish, Vietnamese, Simplified Chinese, Traditional Chinese, Tagalog and Russian.

The website is available now through August 26.

Sound Transit remains committed to working closely with its partners to continue serving the public. Efforts will continue to prioritize serving riders who depend on Sound Transit’s services, including seniors, people with disabilities, Title VI protected populations (race, color, national origin), low-income and limited-English-proficiency populations.

Just two months ahead of the opening of the Lynnwood Link Extension on Aug. 30, Lynnwood City Center Station has earned Leadership in Energy and Environmental Design (LEED) Gold certification from the U.S. Green Building Council. The certification is for the entire station campus, including the station, parking garage and public plaza areas. LEED certification provides independent verification of sustainable design and is a globally recognized symbol of sustainability achievement.

"This LEED Gold certification for Lynnwood City Center Station is a significant milestone, exemplifying our commitment to sustainability," said King County Executive and Sound Transit Board Chair Dow Constantine. "It sets a high standard for future stations and serves as a powerful reminder that the environmental benefits of light rail extend far beyond the transit system itself."

"This achievement is the result of the hard work and shared vision of the construction team, engineers, designers and Sound Transit staff who collaborated on the Lynnwood station," said Terri Mestas, Sound Transit’s Deputy CEO for Mega Capital Project Delivery. "They fulfilled Sound Transit’s commitment to creating a sustainable campus that will serve as a model for future LEED certification of other new Sound Transit stations and that will become a new standard throughout the system."

Key members of the design team were LMN as station architects, HNTB as lead engineers, and O’Brien 360 for sustainability certification. Skanska Constructors L300 JV did the civil construction for the project.

The certification recognized several areas of achievement, including the quality of the transit connections at the station, protection of habitat including restoration of Scriber Creek, energy efficiency of lighting and mechanical systems, and diversion of construction waste.

Specific achievements include the following:

• 30% energy cost reduction vs the ASHRAE 90.1 baseline, with advanced metering for real-time monitoring
• 34% indoor water use reduction through efficient fixtures vs EPA baseline
• 71% reduction in irrigation water use through native, drought-tolerant plant species vs EPA baseline
• 85% of open space covered in vegetation via pedestrian promenade, walkways, bike trails, and planting areas
• 81% of construction waste diverted from landfills
• 100% of paints, coatings, adhesives, sealants, flooring, ceiling, and insulation met LEED low-VOC requirements

Lynnwood City Center Station is the terminus of the Lynnwood Link Extension. The elevated station is served by a five-story, 1,670-space parking garage, which opened last year, and the Lynnwood Transit Center bus exchange which is expected to have 9,500 passenger boardings daily. 

The other stations on the Lynnwood extension are:

• Shoreline South/148th Station. Located just northeast of I-5 at the NE 145th Street exit, the elevated Shoreline South/148th Station includes a parking garage with approximately 500 new spaces as part of the project.
• Shoreline North/185th Station. Located on the east side of I-5, the Shoreline North/185th Station serves Shoreline Stadium, the Shoreline Conference Center and the surrounding neighborhoods. Improved pedestrian pathways connect the station to the west side of I-5. A parking garage with approximately 500 new spaces is part of the project.
• Mountlake Terrace Station. Located east of I-5 at the Mountlake Terrace Transit Center just north of 236th Street Southwest, west of Veterans Memorial Park, the elevated Mountlake Terrace Station straddles 236th Street Southwest, and is a short walk from the Mountlake Terrace Library, new city hall and future transit-oriented development. There are 890 existing parking spaces near the station.
