2 Line service between South Bellevue and Redmond Technology Station began on April 27, 2024.
On May 10, 2025, the 2 Line will open to Downtown Redmond and Marymoor Village.
In late 2025, the Cross Lake Connection will complete the 2 Line between downtown Seattle and Bellevue across I-90 and Lake Washington. 2 Line trains will run every 8 minutes at peak between Downtown Redmond and Lynnwood City Center, serving 26 stations in Redmond, Bellevue, Mercer Island, Seattle, Shoreline, Mountlake Terrace, and Lynnwood.
The 2026 Service Plan (Phase 1) survey is now closed. Stay tuned for updates — we’ll be sharing next steps soon.

Current service
Sound Transit currently provides ST Express service to Redmond, Bellevue, Issaquah and Bothell in east King County. These six ST Express routes serve just under 15,000 riders daily; about 75% are served by routes 545 and 550. All routes except Route 556 operate all day, all week in both directions, with Route 556 providing weekday, peak-only supplemental service.
- 522 // Bothell/Woodinville–Roosevelt
- 542 // Redmond–University District
- 545 // Redmond–Seattle 5th Avenue
- 550 // Bellevue–Seattle
- 554 // Issaquah–Seattle
- 556 // Issaquah–University District
Future service
When the 2 Line Cross Lake Connection opens in late 2025, trains will run every 8 minutes during peak times from Downtown Redmond to Lynnwood City Center via downtown Seattle. 2 Line trains will combine service with 1 Line trains between International District/Chinatown and Lynnwood City Center. Link train frequency will increase to every 4 minutes at shared 1 Line and 2 Line stations during peak times.
2 Line riders looking to access SeaTac/Airport or other stations south of downtown Seattle must transfer to the 1 Line at International District/Chinatown. Riders can expect a trip from the Redmond Technology Station to Bellevue Downtown in 13 minutes and from Bellevue Downtown to Symphony Station in Seattle in 25 minutes.
If you currently ride any of the bus routes listed above, your trip could look different when Link opens. Changes could include:
- Buses that integrate with the growing Link light rail network
- Bus routes that have updated schedules
- More frequent and reliable service throughout the day – trains will arrive about every 8-10 minutes between 6 a.m. and 9 p.m.
- More seats and overall capacity
- More connections to more places throughout the region
- A new option to avoid highway traffic
What have we heard?
Eastside ST Express riders shared their feedback with us during East Link Connections, a community engagement program co-led by King County Metro and Sound Transit from 2021 to 2024. Before opening the 2 Line, we engaged thousands of bus riders in Bellevue, Redmond, Kirkland, Issaquah, and many other Eastside communities to design a better bus network with more connections to the 2 Line. We received hundreds of comments about our proposed ST Express route changes. Riders generally supported our plans to maintain ST Express bus service to major destinations such as UW, South Lake Union, Bellevue, Redmond, Eastgate, and Issaquah.
After this round of feedback, we will develop more specific proposals for east King County ST Express bus service that could change bus frequency, the number of stops, and routes.
We will share and ask for your feedback on these proposals through this online hub in June and July and then will recommend a 2026 Service Plan to the Sound Transit Board of Directors in September. The Board will then vote on the plan as early as October. The plan will take effect as early as 2026.
