Project updates
Like many agencies nationwide that are balancing transit operations and mega-project capital expansions, Sound Transit faces rapidly escalating costs in nearly every area of its work.
The “Enterprise Initiative” is Sound Transit’s comprehensive effort aimed at delivering the maximum benefits of ST3 within available financial resources. As part of this effort, the Sound Transit Board is evaluating different approaches to updating the ST3 System Plan in summer 2026, which may include new ways to build, phase, or sequence projects.

About the project
Sounder South will extend south from Lakewood, adding new stations at Tillicum and DuPont, both with parking. The new stations will help provide service to Joint Base Lewis-McChord as well as to residents and businesses in south Pierce County.
