South Lake Union Feasibility Study Survey
In December 2023, the Sound Transit Board directed staff to assess the feasibility of a potential new alternative in the South Lake Union (SLU) and Denny area. This newly suggested concept would locate the SLU Station roughly two blocks west of the current preferred alternative, near 5th Avenue North and Harrison Street, in tandem with a Denny Station Shifted West, outside of the Westlake Avenue right of way.
As a result, Sound Transit staff studied:
- New tunnel alignment concept
- Station design concept including depth and passenger access
- Environmental implications including roadway closure/access, utilities, noise & vibration, and property effects
- Ridership and equity
- Transit integration
- Cost and schedule implications
- Regional Link system implications
Gathering public feedback on the SLU feasibility study findings is an important part of this work. Please review the information below that outlines the SLU feasibility study findings and compares this new concept to the current Preferred Alternative. Then, tell us what you think about this new concept and the Preferred Alternative. Your feedback will inform the Sound Transit Board which may take action in May to determine whether to add this new concept as an additional alternative for study in the upcoming Ballard Link Extension’s Draft Environmental Impact Statement.
If you would like to learn more before providing feedback, please review this public presentation of feasibility study findings or attend one of the following live webinars in April and May:
