The Link 1 Line runs between Angle Lake in SeaTac and Lynnwood via Tukwila, Seattle, Shoreline, and Mountlake Terrace. In May 2025, the 1 Line had 105,586 average weekday boardings.
The 1 Line initially opened in July 2009 and ran between downtown Seattle (Westlake) and Tukwila. Since then, it has expanded north to the University of Washington in 2016, Northgate in 2021, Lynnwood in 2024, and south to SeaTac in December 2009 and Angle Lake in 2016. The Federal Way Link Extension is expected to open later this year.
The ridership data discussed in this article is just a snapshot of the current system. Link is still a growing system and many of the non-Link transit projects being built in Puget Sound will have a direct or indirect impact on ridership over the next few decades. The methodology behind the data shown below is discussed in the first comment below the post.

Average Weekday Boardings Per Station
The plot below shows the average weekday boarding count by station in each direction in May 2025. Southbound boarding counts are shown on the left and northbound boarding counts are shown to the right. The alighting count for a given station is similar to the boarding count in the opposite direction.
The 1 Line ridership patterns show that the highest ridership occurs between downtown Seattle and Northgate. U District has the higher number of southbound boardings and SeaTac/Airport has the highest number of northbound boardings. All stations north of the Montlake Cut (UW and above) have more southbound than northbound boardings. All stations south of UW have more northbound passengers.
Some observations for each station:
