Sound Transit and the Federal Transit Administration (FTA) recently concluded the National Environmental Policy Act (NEPA) scoping process for the Ballard Link Extension (BLE). The 45-day scoping comment period occurred from Oct. 24 to Dec. 9, 2024. During the scoping period, we sought feedback on the Purpose and Need, alternatives, and potential topics we will study in the BLE Draft Environmental Impact Statement. Thank you to those who gave their input! You can review materials from our in-person scoping meetings online.
About the Ballard Link Extension
The Ballard Link Extension (BLE) will provide fast, reliable light rail connections to dense residential and job centers in the Chinatown-International District (CID), Downtown, Interbay, and Ballard neighborhoods. In addition, a new downtown Seattle light rail tunnel will provide capacity for the entire regional system to operate efficiently. The BLE is part of the Sound Transit 3 system expansion approved by voters in November 2016. The project is currently in the planning phase.
Ballard Link Extension
- Adds 7.7 miles of light rail service from downtown Seattle to the Ballard neighborhood, including a new downtown Seattle rail-only tunnel.
- Includes nine new stations from Chinatown-International District to Ballard.
- Will greatly improve local and regional transit service frequency, reliability, and capacity.
- Facilitates redevelopment near stations, focusing on equitable transit-oriented development (eTOD).
- Start of service is scheduled for 2039.

Environmental review
We’ve been collecting your feedback since 2017 to identify potential alignments and inform our study of the Ballard Link Extension (BLE) alternatives. As part of our environmental review process, we are evaluating a range of alternatives. The scoping comment period, which ended on Dec. 9, 2024, was intended to collect feedback on the Purpose and Need, alternatives, and potential topics to be studied in the BLE Draft Environmental Impact Statement (EIS).
Next, Sound Transit will develop a new BLE Draft EIS in coordination with the Federal Transit Administration (FTA). The Draft EIS comment period, anticipated in 2025, seeks feedback on potential environmental impacts and benefits of each alternative proposed actions that will help mitigate impacts. We will carry forward public feedback and comments collected from the start of the project as part of the ongoing environmental review phase.
As a reminder, after the publication of the West Seattle Ballard Link Extensions (WSBLE) Draft EIS and a 90-day comment period in 2022, the Sound Transit Board directed Further Studies of BLE alternatives. These Further Studies led to Board actions in March and July 2023 that added new alternatives and modified the preferred alternatives for the BLE. Given the additional environmental review needed for these project refinements, staff determined that the WSLE and BLE projects would continue to advance on two separate environmental review timelines. The BLE requires a new National Environmental Policy Act (NEPA) Draft EIS/State Environmental Policy Act (SEPA) Supplemental Draft EIS, with publication anticipated in 2025.
The purpose of the project is to expand the Sound Transit Link light rail system from SODO to Ballard, to make appropriate community investments to improve mobility, and to increase capacity and connectivity for regional connections to achieve the following:
- Provide high-quality rapid, reliable, and efficient light rail transit service to communities in the project corridor as defined through the local planning process and reflected in the Sound Transit 3 Plan (Sound Transit 2016).
- Improve regional mobility by increasing connectivity and capacity through Downtown Seattle to meet the projected transit demand.
- Connect regional centers as described in adopted regional and local land use, transportation, and economic development plans and Sound Transit’s Regional Transit Long-Range Plan (Sound Transit 2014a).
- Implement a system that is technically and financially feasible to build, operate, and maintain.
- Expand mobility for the corridor and the region’s residents, which include transit-dependent residents, low-income people, and communities of color.
- Encourage equitable and sustainable urban growth in station areas through support of transit-oriented development and multi-modal integration in a manner that is consistent with local land use plans and policies, including Sound Transit’s Equitable Transit Oriented Development Policy (Sound Transit 2018) and Sustainability Plan (Sound Transit 2019).
- Encourage convenient and safe non-motorized access to stations, such as bicycle and pedestrian connections, consistent with Sound Transit’s System Access Policy (Sound Transit 2013).
- Preserve and promote a healthy environment and economy by minimizing adverse impacts on the natural, built, and social environments through sustainable practices.
The project is needed because:
- When measured using national standards, existing transit routes between SODO and Ballard currently operate with poor reliability. Roadway congestion in the project corridor will continue to degrade transit performance and reliability as the city is expected to add about 287,000 people and about 214,000 jobs between 2018 and 2050 (Puget Sound Regional Council 2023).
- Increased ridership from regional population and employment growth will increase operational frequency in the existing Downtown Seattle Transit Tunnel, requiring additional tunnel capacity.
- Puget Sound Regional Council (the regional metropolitan planning organization) and local plans call for high-capacity transit in the corridor consistent with VISION 2050 (Puget Sound Regional Council 2020) and the Regional Transit Long-Range Plan (Sound Transit 2014a).
- The region’s residents and communities, including transit-dependent people, low-income people, and communities of color, need long-term regional mobility and multi-modal connectivity as called for in the Washington State Growth Management Act (Revised Code of Washington 36.70A.108).
- Regional and local plans call for increased residential and/or employment density at and around high-capacity transit stations and increased options for multi-modal access. VISION 2050 has a goal for 65 percent of the region’s population and 75 percent of the region’s employment to occur in regional growth centers and within walking distance of transit.
- Environmental and sustainability goals of the state and region, as established in Washington state law and embodied in Puget Sound Regional Council’s VISION 2050 (2020) and 2022-2050 Regional Transportation Plan (2022), include reducing greenhouse gas emissions by prioritizing transportation investments that decrease vehicle miles traveled.
November 2016: Sound Transit 3 Ballot Measure
- Sound Transit 3 (ST3) is approved by voters. This plan includes adding 62 new miles of light rail, totaling more than 116 miles with over 80 stations added to the region. Part of this plan includes the West Seattle Link and Ballard Link Extensions (WSBLE) projects, other projects like the bus Rapid Transit (BRT) on the Eastside, additional capacity for the Sounder South line, and access improvements to stations for all modes of travel.
