News & Events

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.

The Institute for Sustainable Infrastructure (ISI) has awarded Sound Transit’s Federal Way Link Extension an Envision Platinum Award for sustainable infrastructure for going above and beyond to deliver improvements to the social, economic and environmental conditions of its community.

The Federal Way Link Extension is both the second Sound Transit project and the second transit project in the Pacific Northwest to receive verification by ISI, and only the seventh Envision Platinum-rated transit project in the nation. Envision is an internationally recognized rating system for sustainable infrastructure projects. This award is issued following a comprehensive independent peer-review process conducted and overseen by ISI that verified the project accomplishments. The evaluation assessed the project’s performance across 64 sustainability criteria addressing a wide range of indicators including: community, quality of life, management, planning, materials, energy, water, environmental impacts, emissions and resilience.

The design-build contract for FWLE stipulated the need for the project to attain at least an Envision Gold award level. Through the combined efforts of the Sound Transit project team and sustainability group and Parsons, the project’s lead design team, and design-build contractor Kiewit, platinum was achieved.

“We are honored to present the Envision Platinum award to the Federal Way Link Extension project, recognizing its outstanding commitment to sustainability, equity and resilience,” said Kristi Wamstad, ISI’s Verification Director. “This achievement underscores the project team's dedication to creating a transit system that prioritizes environmental stewardship and social equity while meeting the needs of the community.”

“This award is a testament to Sound Transit’s long and deep commitment to sustainability and to the high levels of collaboration achieved with our project partners during challenging times,” said Sound Transit Chief Executive Officer Goran Sparrman. “We are proud of this achievement and look forward to many more sustainability milestones as we build public transit that connects our region to the places we live and work.”

“As a global leader in infrastructure, Parsons is transforming the rail and transit sector by providing innovative, tailored solutions that modernize transportation systems and deliver long-lasting, sustainable benefits to our clients,” said Mark Fialkowski, president, Infrastructure North America for Parsons. “Our contribution to the Federal Way Extension project represents Parsons’ combined engineering expertise and enterprise-wide commitment to sustainability. We are honored to be part of the team that achieved this award by creating a lasting, valuable public asset for the region and community.”

“Kiewit is proud to be the design-build contractor for Sound Transit’s Federal Way Link Extension, a project that showcases innovation in sustainable infrastructure. Strong partnerships, particularly with the community, are essential to our success,” said Kiewit Corporation Executive Vice President Doug Glaser. “We would not be able to accomplish what we did without the remarkable people we had on the team, including the 400 local union tradespeople and the 200 subcontractors and suppliers who came together with our construction and engineering staff to achieve a common goal.”

Set to open in 2026, the Federal Way Link Extension extends light rail from Angle Lake Station in the city of SeaTac to downtown Federal Way. The 7.8-mile extension includes three stations: Kent Des Moines near Highline College, Star Lake at South 272nd Street and Federal Way Downtown. More information about the project is can be found on the Federal Way Link Extension page. 

In 2022, the Downtown Redmond Link Extension was the first Sound Transit project to complete Envision verification and received Envision Platinum. Sound Transit anticipates pursuing Envision verification for all its future light rail expansion projects.

Seasoned professional with more than 30 years of experience will fill newly created position to oversee delivery of capital programs

Sound Transit today announced that Terri Mestas has been appointed as deputy CEO for megaproject delivery, a new position created to lead the development of the agency’s concurrent projects quickly and effectively and bring forth ways to accelerate project timelines and reduce capital expenditures. Sound Transit currently has the largest transit expansion program in the country, including ST3 capital projects totaling an estimated $54 billion. Mestas will start in her new position on April 29.

“The next phase of Sound Transit’s expansion is categorically different than what the agency has done before, which is why the Board sought an experienced leader to deliver on our commitment to voters,” said Sound Transit Board Chair and King County Executive Dow Constantine. “With her background as a leader of large, complex infrastructure programs, Ms. Mestas brings the depth of experience and expertise that the agency needs to set the nation’s largest capital expansion project on a fresh path to success.”

“With the opening of the Lynnwood Link Extension just months away, we are even more focused on extending light rail to Everett,” said Sound Transit Vice Chair and Snohomish County Executive Dave Somers. “The Everett Link Extension will be the longest extension that Sound Transit will have ever undertaken and will be vital for enhancing economic opportunities and quality of life for Snohomish County residents. I’m pleased that Ms. Mestas will bring her wealth of experience to oversee this complex project, as well as all the ST3 projects.”

“Since before ST3’s approval in 2016, it’s been clear that voters want Sound Transit to build capital projects faster. Hiring a deputy CEO of megaproject delivery represents a critical next step in delivering transformative transit for our region,” said Sound Transit System Expansion Committee Chair and King County Councilmember Claudia Balducci. “By implementing a key recommendation of the Technical Advisory Group, today’s announcement is a huge step forward to accelerate project delivery. We’re fortunate that Ms. Mestas is willing to bring her incredible experience to take on this challenge. I look forward to collaborating with her and her team to execute on that commitment to build fast, frequent, reliable transit for the people of Central Puget Sound.”

“It is absolutely essential that a culture of accountability and delivery is instilled at Sound Transit, especially while managing the largest transit megaproject in the nation,” said Sound Transit Board Member and Pierce County Executive Bruce Dammeier. “That’s why I’m excited we have brought on Terri Mestas as Sound Transit’s first deputy CEO of megaproject delivery. Our communities have been paying taxes for decades and we have to make sure we are delivering for the entire region – including Pierce County. A leader like Terri is critical to accomplishing this.”

“Sound Transit’s capital program needs a strong leader who understands and can manage complex, multibillion dollar programs,” said Grace Crunican, chair of the Technical Advisory Group, or TAG. “TAG members were part of the selection process and believe Ms. Mestas is the right choice to deliver this program.”

“I’m excited to be joining Sound Transit at this critical juncture in its transformative capital program,” said Mestas. “The hard work and dedication of the talented staff have been essential to the program’s success to date, and I look forward to working with them in taking the program to the next level in achieving the goals that voters have entrusted to us.”

Mestas is a seasoned professional with more than 30 years of experience leading large, complex infrastructure programs for space exploration, military installations, national and international antiterrorism physical security, and innovative project delivery for the aviation industry. Most recently, she was the chief development officer for the Los Angeles World Airports’ (LAWA) $30 billion capital improvement program, the largest aviation capital improvement program in the nation.

Prior to her executive leadership role at LAWA, Mestas held several positions for AECOM supporting public and private organizations. Mestas led the capital improvement program at NASA’s Ames Research Center, which includes Moffett Federal Airfield, a joint civilian-military airport. She also held the position of senior director for capital projects, modernization, planning, design and construction at The California Institute of Technology, where she oversaw the development of one-of-a-kind research facilities. Mestas earned a Bachelor of Architecture from Catholic University of America’s School of Architecture and Planning.

The region is home to more than 50 cities and more than 40 percent of the state’s residents, who have authorized the most ambitious transit expansions in the nation. Next month, Sound Transit will open the light rail extension from South Bellevue to Redmond Technology Center and later this year to Lynnwood.

The Sound Transit Board of Directors today approved the one-year appointment of Goran Sparrman as the agency’s interim CEO. 

"In the next nine months, we will expand Link light rail at a scale never before seen at the agency, and we’re excited to have Goran’s skillset and background leading the way," said Sound Transit Board Chair and King County Executive Dow Constantine. "This is ambitious, exciting and, of course, daunting. The Board believes in Goran’s ability to lead the agency through this transformative period of growth while continuing to focus on delivering reliable, frequent, and safe transit service for all our passengers."

"I am looking forward to joining with the dedicated professionals at Sound Transit to celebrate the upcoming successes and tackle the challenges ahead," said Sparrman. "By working together creatively and efficiently, I am confident that we will be able to deliver for the residents of our region."

Sparrman’s first day at the agency will be Jan. 13. Departing CEO Julie Timm’s last day at the agency is Jan. 12. Timm announced her resignation last month in order to return to the East Coast to take care of family matters.

"With his extensive public and private sector experience in Puget Sound region transportation planning and operations, and familiarity with Sound Transit, Goran will bring a unique skillset to help the board and staff drive the agency forward," said Sound Transit Board Chair and King County Executive Dow Constantine. "Goran will be able to quickly step into leadership of the staff and seize the opportunities of the two new rail extensions opening this year, while continuing development of the largest transit expansion in the nation, to ensure Sound Transit’s success."

"Goran is well-respected for his skill and knowledge in transportation and infrastructure projects," said Sound Transit Vice Chair and Snohomish County Executive Dave Somers. "He’s a trusted regional leader who would bring a steady hand to an agency with which he is already familiar."

"In my years of experience working with Sound Transit, I know the staff to be dedicated professionals committed to building and operating the transit system our region deserves," Sparrman said. "I’m looking forward to collaborating with them as we build on the successes that are coming this year and look for solutions for the challenges that lie ahead."

Sparrman would bring more than 30 years of experience in the public and private sector to the interim CEO role. His most recent position has been as business development officer and vice president at HNTB Corporation, a major infrastructure firm.

Prior to joining HNTB, from 2011 to 2014 Sparrman served as the deputy director and interim director of the Seattle Department of Transportation, where he led planning, design, building, maintenance, and operations of Seattle’s transportation infrastructure. He was also Director of the City of Bellevue Transportation Department for 12 years, where he worked closely with Sound Transit on the planning for the East Link Extension.

Moody’s Investor Service has affirmed its “Aaa” ratings for Sound Transit’s first lien “Prior Bonds,”— the highest possible for tax-backed bonds—as well as its “Aa1” rating on second lien “Parity Bonds.” The bond ratings affect approximately $1.9 billion in debt.

“The affirmation of these bond ratings is a vote of confidence in the strong financial stability of Sound Transit,” said Sound Transit Board Chair and King County Executive Dow Constantine. “These ratings save taxpayers money and underscore why good stewardship of public funds is our guiding principle.”

“These bond ratings are a particularly encouraging endorsement of Sound Transit’s ongoing fiscal strategies given the financial challenges currently faced by transit agencies across the country,” said Sound Transit CEO Julie Timm. “The agency is demonstrating that it has the structure and policies in place to weather the headwinds that transit as a whole faces in this country.”

Moody’s based the ratings on Sound Transit’s robust debt service coverage by pledged revenues as well as the size and strength of the service area's economy from which the pledged revenue is generated. The ratings also incorporate the overall growth trend of pledged revenues with manageable historical volatility, the bonding programs' adequate legal provisions, and the authority's very large capital expansion plan that could entail significant additional borrowings over the longer-term. The ratings also consider demonstrated voter support for Sound Transit's transportation programs and the agency’s strong management.

Sound Transit CEO Julie Timm announced today she will be leaving the agency in order to return to the East Coast to take care of family matters. Since joining Sound Transit in September 2022, Timm has overseen a renewed emphasis on the rider experience as Sound Transit approaches the opening of several new extensions, starting with East Link next spring. Her focus and leadership in centering current and future riders in the agency’s capital and operating programs will benefit the region for years to come.

Timm’s last day with Sound Transit will be January 12th. 

The board and staff leadership will form a transition team to navigate the agency through the leadership transition. The board is expected to appoint an interim CEO in the weeks ahead.

The Sound Transit Board has awarded a design-build contract for the Kent Station parking garage to Absher Construction of Puyallup. When complete in 2027, the $62.5 million project will include a new structured parking facility, additional surface parking and other associated access improvements which will serve Sounder S Line, Sound Transit Express, and King County Metro passengers.

The U.S. Department of Transportation today announced that its Build America Bureau has provided low-interest loans totaling $327 million to the Central Puget Sound Regional Transit Authority (Sound Transit) for improvements to the transit system. By providing Transportation Infrastructure Finance and Innovation Act (TIFIA) and Railroad Rehabilitation & Improvement Financing (RRIF) Loans. The Bureau helps communities expedite infrastructure projects and reduce project costs.  

“DOT's $327 million in loans to support Sound Transit’s light and commuter rail lines supports an alternative to car travel on congested roadways and improve connections to jobs, healthcare, and educational opportunities,” said Deputy Transportation Secretary Polly Trottenberg. “Construction of these three new projects will reduce carbon emissions and improve air quality.”

The TIFIA and RRIF loans will finance three projects:

• Hilltop Tacoma Link Extension (TIFIA loan for $93.3 million, 33 percent of total $282.7 million cost), which will
  • Extend light rail line by 2.4 miles
  • Build six new stations and relocate one station
  • Purchase five new light rail vehicles
  • Improve bike/pedestrian infrastructure
  • Expand an operations and maintenance facility
• Elevated Light Rail Platform Along Lynnwood Link Extension (TIFIA loan for $79.3 million, 33 percent of total $240.2 million cost), which will:
  •  Build a new light rail station in North Seattle
  • Build new bus and paratransit facilities
  • Add sidewalk and bike infrastructure
• Sounder Access Improvements (RRIF loan for $154.2 million, 49 percent of total $314.6 million cost), which will:
  • Improve access for hundreds more people at three stations
  • Construct new sidewalks and improve street lighting
  • Expand existing, insufficient parking facilities for transit users without the ability to walk or bike to a station

“Sound Transit is our largest borrower, now at $4.17 billion,” said Bureau Executive Director Morteza Farajian. “They are leveraging low-interest financing to build critical projects that will benefit passengers for years to come.” 

Sound Transit estimates the loans will save $245 million through 2046, when the agency's voter-approved expansion plan is expected to be completed, and a total of $445 million over the entire life of the three loans. 

“Strong partnership with the federal government is crucial to our success, and these loans signal a shared commitment to reinvest in the nation’s infrastructure and help us build the transit network our region needs,” said Sound Transit Board Chair and King County Executive Dow Constantine. “We thank USDOT and our congressional delegation for investing in residents’ future.” 

The Build America Bureau advances investment in transportation infrastructure by lending Federal funds to qualified borrowers; clearing roadblocks for credit worthy projects; and encouraging best practices in project planning, financing, delivery, and operations. The Bureau draws on expertise across DOT to serve as the point of coordination for states, municipalities, private partners, and other project sponsors seeking Federal financing.

To date, the DOT has closed more than $38.9 billion under TIFIA financing program, supporting more than $133 billion in infrastructure investment across the country and $7.6 billion under RRIF program.
