Upcoming Link Maintenance: March 2026

1 Line replacement bus at Westlake station.

Sound Transit's monthly maintenance program is continuing in March with several service reductions over the next few weeks.

Reduced Frequency

Starting at 11pm tonight, 1 Line trains will run every 20 minutes. The reduced frequency is to allow single-tracking trains between Rainier Beach station and Tukwila International Blvd Station. The 1 Line will resume its normal headways at 5am Sunday morning.

Pinehurst Station Construction

To accommodate Pinehurst station's ongoing construction, 1 Line and 2 Line service will be altered after 11pm Monday-Friday next week. On Monday (3/2) and Friday (3/6), 1 Line trains will single track between Northgate and Shoreline South. 2 Line trains will terminate at Northgate station. After 11pm on Tuesday, Wednesday, and Thursday next week, replacement buses will be used between Northgate and Lynnwood. The 1 Line will continue to operate between Federal Way and Northgate. The 2 Line will run between Downtown Redmond and South Bellevue, and between International District/ Chinatown and Northgate.

Downtown Seattle Transit Tunnel Closure

On March 21 and March 22, replacement buses will be used between Capitol Hill and Stadium. The Downtown Seattle Transit Tunnel (DSTT) will be closed so Sound Transit crews can replace a defective rail near Pioneer Square. This is the first DSTT closure since the 2 Line began simulated service earlier this month. Sound Transit has not specified how the closure will affect 2 Line service, but we will update this post when we know more.

Service reductions are an unfortunate reality of a growing transit network. It is better for Sound Transit to proactively perform preventive maintenance now rather than wait for something to break.
