Sound Transit Express – South Sound Service Change Proposal
With the upcoming opening of Federal Way Link, travel patterns in the South Sound are expected to shift significantly. To prepare for this change, the Central Puget Sound Youth Transportation Alliance (CSYTA) has developed a set of proposed adjustments to the ST Express network to better integrate with Link light rail, improve regional connectivity, and reduce duplication.
We are currently seeking feedback from riders, community members, and stakeholders to help refine these proposals. Your input will play an important role in shaping a network that meets the needs of South Sound residents while ensuring efficiency and reliability.

As a youth-led organization, we focus on timely issues affecting transit in the Puget Sound region. Our priorities shift as projects evolve and new needs arise. Here are the initiatives we’re currently paying attention to.
As East Link stations begin to open, we’re focused on making sure youth can actually use them. That means fighting for strong local bus connections, pedestrian-friendly access, and service hours that align with student and part-time worker schedules. We’re especially keeping an eye on:
Mercer Island’s limited local bus service
Redmond’s connections to neighborhoods and Microsoft
Transit priority and congestion relief on Bellevue Way SE
The Federal Way Link Extension will bring light rail service into South King County, opening new opportunities for youth to access schools, jobs, and activities across the region. We’re focused on ensuring that:
Sound Transit Express buses provide fast, reliable connections between Link stations and key destinations in Pierce County not currently well-served by Link.
Local transit agencies like King County Metro and Pierce Transit coordinate east-west routes to connect Link stations with nearby Sounder commuter rail stops, making cross-regional travel smoother
Transit schedules and infrastructure support easy transfers, minimizing wait times and improving overall rider experience for everyone
Many youth in Pierce County rely on buses that come once per hour — or not at all on weekends. We’re pushing for:
Better weekend and evening service on key Pierce Transit routes
Reliable connections between Tacoma, suburban neighborhoods, and schools
More efficient use of resources and better regional coordination with Sound Transit Express buses
The Sounder train is fast and comfortable — but underused by youth due to limited viable trips and lack of awareness. We’re working to:
Promote Sounder S line through videos, social media, and school outreach
Make Sounder N line useful for more trips
Consider how Amtrak Cascades services can complement both Sounder lines
Sound Transit’s STRIDE BRT network (S1, S2, and S3) will act as an orbital transit service connecting Link Light Rail and neighborhoods across the region. However, success depends on more than building bus lanes—it’s about making the right decisions now that will affect riders for decades. We’re focusing on:
Route Choices: STRIDE routes prioritize direct routes for faster travel instead of making more connections
Bus Priority must also be given when buses leave express lanes to prevent delays
STRIDE is designed to connect Link, Sounder, and local buses. We advocate for frequent service, accessible stations, and clear, rider-friendly signage and shelter.
