On Aug. 5, 2021, the Sound Transit Board adopted a realigned capital plan to address steeply rising construction and real estate costs affecting many voter-approved regional transit expansion projects. The Board’s adopted plans identify 2032 as the earliest date we could open Link light rail service to South Federal Way, Fife and Tacoma.

Some projects in the planning phase, including the TDLE, have also experienced non-financial delays in recent months. Many government and community project partners were forced to shift resources to addressing the human impact of the COVID-19 pandemic and were justifiably unable to review planning and environmental documents during that time. 

When combined with our own delays, these delays in individual agencies and organizations had a compounding effect on some project schedules, including the TDLE, which would face opening date delays of up to two years even if projected financial impacts are eliminated. 

The Board’s adopted plan also identifies 2038 as the timeframe we can afford to open the South Federal Way and Fife station parking facilities associated with TDLE. The ultimate timeline for parking facilities will come into greater focus as we advance the environmental review process and project design, including examining cost-saving options.
