1 Line service is significantly reduced from Monday, April 14 through Wednesday, April 23 due to planned maintenance. Plan ahead for additional travel time.
In effect: April 14-24
Routes: 1 Line
Planned maintenance is necessary at this time to replace a section of rail south of the International District/Chinatown Station.
During this time trains are operating approximately every 12 minutes between Lynnwood City Center and Westlake and from Stadium to Angle Lake stations.
Passengers must transfer trains at Westlake and Stadium stations to continue to downtown Seattle stations, where trains are running about every 25-30 minutes. All trains are sharing the northbound platform at Symphony, Pioneer Square, and International District/Chinatown stations. Please follow in station signage and train signage to ensure that you board the correct train.
Passengers traveling from Snohomish County should consider other transit options, including the N Line, Route 510, and 515 on weekdays, to avoid the disruption entirely. For additional flexibility, Community Transit has added trips to the 515 during the tunnel closure.
Passengers should plan for significant increases in travel time and consider alternate forms of transportation, especially local bus service for those traveling to a location between Westlake and Stadium stations. In addition to scheduled service, King County Metro will be providing a "downtown circulator" bus on weekdays during the evening commute to help reduce crowding.
