RapidRide K Line
Coming to Kirkland and Bellevue
Metro is working to bring new RapidRide service to the Eastside, to provide better, more reliable bus service to communities in Kirkland and Bellevue. By 2030, Metro plans to bring RapidRide K Line to the fast-growing communities between Totem Lake Transit Center, downtown Kirkland, downtown Bellevue and the Eastgate Park-and-Ride.
Project overview
Metro plans to bring RapidRide to more Eastside communities by 2030. The RapidRide K Line will serve a 16-mile north-south corridor between Kirkland and Bellevue as part of Metro Connects, Metro’s long-range vision approved by the King County Council in 2017.
Metro ridership continues to increase since the impact of COVID-19. In October 2024, RapidRide routes were reporting an increase of over 4,600 average weekday boardings compared to October 2023, including an increase of 7.6% for the RapidRide B Line serving Bellevue and Redmond. The RapidRide G Line replaced former Metro Route 11. Prior to RapidRide G Line construction, Route 11 carried an average of 1,800 people (weekday for September 2023), Now in service, the G Line carries over 4,000 average weekday riders (data for November 2024).
Existing eastside service on routes 225, 239, 245, 250, 255 and 271 have also seen a yearly increase in average weekday ridership. Approximately 1,400 new trips were taken on average in October 2024, compared to October 2023.
The expansion of RapidRide will continue to bring riders high-quality, more frequent and reliable service with better connections to other buses and modes of transportation. Improving the Eastside transit network is necessary to serve the fast-growing communities of Kirkland and Bellevue. The RapidRide K Line will provide connections to major transit services in the area, including Sound Transit’s Link light rail 2 Line, existing RapidRide B Line and the I-405 Stride Bus Rapid Transit planned for service in 2030. The K Line will serve many major employers in the medical, technology and aerospace industries, as well as several universities and other popular destinations.
Originally planned to begin service in 2025, Metro paused work on the RapidRide K Line due to funding issues caused by the COVID-19 pandemic. Metro is committed to engaging key partners and eastside communities as project work starts up again with a planned launch of the service by 2030.

FAQ
Project notifications were sent to landowners along the K Line route during Phase 2 of community engagement. The next phase will include preliminary design, which will further identify any potential property impacts. Once a potential impact is identified, the property owner will be contacted. If property owners are not contacted, it means there is no planned impact to the property. No matter the impact level, all property owners along the route will continue to receive project notifications throughout the project lifecycle.
During the preliminary design phase, if the project team identifies a right-of-way need, the property owner is contacted directly by Metro (with support from city partners). Property owners can participate through the larger community engagement process and impacts to their property are not decided without a Metro conversation. Metro plans to identify these property impacts during the preliminary design phase starting in 2025. Affected property owners would be contacted by summer/fall of 2025.
Ridership projections were developed in 2019, however ridership trends have shifted following the COVID-19 pandemic which saw a national decrease in transit ridership. King County continues to see an increase in riders and some routes are back at (or near) previous ridership levels. The project team is revising ridership projections to reflect these new conditions and will have revised ridership for the K Line in early 2025.
For comparison, the RapidRide B Line which serves eastside cities of Bellevue and Redmond is reporting 76% ridership recovery (as of Oct. 2024). Route 250 is reporting 58% ridership recovery (as of Oct. 2024). Route 239 and 250, introduced in 2020, have seen ridership growth each year and are currently averaging 700+ and 2500+ average weekday boardings.
The projected travel times with proposed improvements for the K Line are 68 minutes for northbound travel (from Eastgate Park-and-Ride to Totem Lake Transit Center) and 70.1 minutes for southbound travel (from Totem Lake Transit Center to Eastgate Park-and-Ride).
By comparison, corridor travel times without any proposed improvements would be 88.5 minutes northbound and 96.5 minutes southbound.
Note: the travel times reported above are for the Weekday PM Peak Hour, which is typically 3 pm to 7 pm.
The new RapidRide K Line route will include a restructure of surrounding transit service. This restructure will include a separate engagement process with city partners and community, in order to identify local routes that should be included in the service restructure and how the new, proposed transit network can best meet community needs. A service restructure will aim to reduce duplication of service and deliver a unified transit network that will maximize frequency, coverage area and timely connections to other regional transit service.
The $120 million is the planning-level estimate to deliver RapidRide service to meet national and county standards for bus rapid transit. The project budget includes new and upgraded stations with enhanced passenger amenities, ADA compliant ramps and other access projects, such as sidewalks and new crosswalks. All new features will be designed provide safe and convenient access to bus stations, as well as transit priority improvements (new bus signal technology and transit lanes, etc.) to ensure the RapidRide service is fast, reliable and frequent.
The project budget is assumed to be a 50/50 split between federal funds and a local funding match, of $60 million each. The cost of operation is not included in the project budget.
