Ballard Light Rail At-Grade

Originally around 2013, the Ballard Link Extension was envisioned as an at-grade alternative. Transit advocates and others pushed for complete grade separation for faster speed and reliability. Sound Transit extended the ST3 a decade and convinced the other sub areas to help fund a second transit tunnel. Unfortunately the preferred Ballard Link Extension has faced large cost overruns from $5.2 billion dollars to now $10.8 billion. In light of the eye-watering cost increases, a second look at the original at-grade options studied in the early 2010s should be considered.

Automate Ballard Link

Sound Transit is currently in the planning phase of building the Ballard Link Extension (BLE). These plans currently include a second downtown Seattle transit tunnel parallel to the one currently used by the 1 Line. By 2026, trains will run Lynnwood – Federal Way and Lynnwood – Redmond using this tunnel. Once all planned link extensions are completed (est. 2041), the plan is for trains to run Mariner-Redmond and Everett-West Seattle via the existing downtown tunnel (DSTT1). The new tunnel (DSTT2) will be underused, with only Ballard-Tacoma trains. The alignment options for DSTT2 between Westlake and International District bypass dense neighborhoods east of I-5 while failing to meaningfully improve transit options within Downtown Seattle. Instead, Sound Transit should build an independent, automated Ballard – Westlake line.

Weekend Link Disruptions Extended

Sound Transit’s guide to the bus shuttle that will run between Capitol Hill and SODO Stations in upcoming service disruptions.

As planned late last year, Link service has been disrupted for several weekends this winter as Sound Transit works to complete several projects requiring closure of track in Downtown and the U-District. The final planned disruption was scheduled for this weekend (February 21 to 23) as a contingency weekend in case work completed the previous weekend needed more time.

This week, Sound Transit announced they would be making use of part of the contingency weekend and an additional weekend to complete additional work. Link 1 Line service between Capitol Hill and SODO stations will be replaced by bus shuttles on Sunday, February 23, returning to normal service during the week. Link 1 Line service will then be replaced by bus shuttles between Capitol Hill and SODO stations from 10pm on Friday, February 28, to end of service on Sunday, March 2.

Federal Way Link Stations and Walkability

Edit, 11:40am, February 21: Sound Transit provided a newer map of the Federal Way Station area, reflecting a design change moving the bus terminal to be directly adjacent to the light rail station. The article has been updated with this information.

Since Federal Way Link is opening in 2026, here’s a brief overview of the 3 stations opening next year and their layout. The diagrams are from the open house and photos from City of Kent and Sound Transit. The stations’ existing poor walkshed will be improved with a new street grid. Biking to destinations east of I-5 will be moderately improved by new bridges, though new I-5 off/on ramps will also increase car to bicycle conflicts.
