More King County Metro bus service starting March 29

King County Metro will update schedules and increase bus service starting March 29. Improvements include hundreds of new weekend bus trips on key routes that are supported by the Seattle Transit Measure.

“Metro ridership is growing as more people embrace the region’s fast, frequent, and reliable transit network, seamlessly connecting buses and trains,” King County Executive Dow Constantine said. “With new Eastside train stations opening this spring, riders will enjoy even better community connections.”

“By expanding weekend bus service on key routes, we’re making it even easier for Seattle residents to leave their cars at home and travel to every corner of our beautiful city,” Seattle Mayor Bruce Harrell said. The Seattle Transit Measure, approved by voters in November 2020, supports transit access and frequency citywide and is funded by a 0.15% sales tax through early 2027.

“Morning, noon and night, our transit operators are safely and reliably connecting our community to where they need to go every single day – 300,000 boardings each weekday and counting,” Metro General Manager Michelle Allison said. “Our ridership reached nearly 90 million in 2024 and we’re welcoming more riders each day. As we celebrate Transit Appreciation Week, we’re so very grateful for our Metro employees who will expertly deliver these service changes, as well as our public transportation every day.”

Service highlights

Seattle Transit Measure funded

• Route 8: Eight new trips will be added on Saturday and 33 new trips will be added on Sunday. 

• Route 36: 14 new trips will be added on Saturday and 36 new trips will be added on Sunday. 

• Route 56: This route will have one fewer trip each weekday during the morning commute hours, which is a reduction in trips that are currently funded by the Seattle Transit Measure. These service hours will be re-invested in other routes to better meet the City’s policy goals and equity commitments.

• Route 107: Six trips will be added on weekdays, 61 trips will be added on Saturday and 63 trips will be added on Sunday. 

• Route 124: One trip will be added on Saturday and two trips will be added on Sunday. 

• RapidRide C Line: Buses will come about every 10 minutes or more frequently. This route will have fewer trips during afternoon commute hours, some of which were funded by the voter-approved Seattle Transit Measure. This change is to support Seattle’s equity goals, better align with transit need and demand, and be consistent with Metro’s RapidRide policies.

• RapidRide G Line: Two late night trips will be added for both weekday and weekend service. 

• RapidRide H line: Five trips will be added on weekdays and three trips will be added on Saturday and Sunday.
