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.

Overview
As a primary destination for Sounder riders, King Street Station can sometimes feel crowded, especially on stairs and in elevators. As part of the Sounder South Capacity Expansion program, we’re studying how to make King Street Station better for passengers and ready to serve more Sounder riders in the years ahead. We’re looking into adding more stairs and elevators, a concourse above the platform, and more!
