However, the board directed staff to also carry forward the Denny Station on Terry (i.e., South Lake Union Mix and Match) alternative as part of ongoing environmental review and to further clarify the technical, financial, schedule and risk implications of both alternatives. The board did not modify the previously identified preferred alternative for the Denny Station located on Westlake in the Draft EIS alternative. The board also directed the CID 4th Avenue Shallower option be carried forward for additional environmental review. The preferred alternative includes stations south and north of the Chinatown-International District (CID) and shifts the Midtown Station to the location north of CID. The tunnel is a key component of the proposed extension but would serve Sound Transit’s entire light-rail system. The proposed downtown Seattle to Ballard 7.1-mile extension includes nine new stations and a new rail-only tunnel through downtown Seattle. 'Through extensive engagement with community members and collaboration with key partners, we have identified a preferred alternative for the Ballard Link Extension that is affordable, accessible and equitable.' 'Today we are closer than ever to realizing a connected regional light-rail network that will serve transit riders and become the template for our region’s future success,' said Sound Transit Board Chair and King County Executive Dow Constantine.

A final decision on the alignment will be made following conclusion of the Final Environmental Impact Statement (EIS) the Draft EIS was released in July 2022. The board explained community priorities, regional needs, city of Seattle and agency input all weighed into its decision on the preferred alternative. The Sound Transit Board has identified a preferred alternative for the Ballard Link Extension on March 23, about eight months after the board requested further study and community engagement of the project’s alternatives.
