Today, Sound Transit and project partners celebrated the advent of heavy construction on the Sumner Parking Access Improvement project with a groundbreaking ceremony. When complete in 2026, the $49 million garage will serve Sounder S Line passengers and users of Sound Transit Express services. The 600-stall garage will provide approximately 500 net new parking spaces at the station. Currently, the existing parking at Sumner Station is routinely full very early in the morning.

“This project will provide increased access to Sounder, increased access to the region, and increased access to economic opportunity,” said Sound Transit Board Vice Chair and Fife Mayor Kim Roscoe. “As a Sound Transit Board Member from the South Sound and as a resident of Pierce County, it’s great to see our region’s investments in a robust transit system moving forward.”

“Given that Sumner was the first station to bounce back to 100% capacity after the pandemic, we know what a priority this project is for the community. Giving people more access to regional transit, and more options to travel, benefits us all,” said Sound Transit Interim CEO Goran Sparrman.

Previously, Sound Transit contributed $7.5 million for pedestrian, bicycle, lighting and ADA improvements to the Sumner station area. That work was performed by the city of Sumner.      

Sound Transit's Sounder S Line train service gives Pierce County residents a dependable, traffic-free commute to and from Seattle. The trip, with Wi-Fi, from Sumner Station to Seattle's King Street Station takes about 40 minutes. Weekend service is also offered for select major sporting events.

Sumner Station is also served by Sound Transit Express buses 578 and 596. Find S Line and ST Express schedule information here.
