Online Open House for Sumner Station Parking and Access Improvements project now live

An online open house is now available to learn more about the Sumner Station Parking and Access Improvements project. When complete in early 2026, the new garage, to be built on the site of the station’s current surface parking, will serve Sounder S Line passengers and users of Sound Transit Express services. The 602-stall garage will provide 505 net new parking spaces at the station. Currently, the existing parking at Sumner Station is routinely full very early in the morning.

The online open house provides information on the garage design (subject to refinement or change), a new landscaped plaza, new bike lockers, and potential construction impacts and parking alternatives during construction.

Additionally, in-person information is available at the following times and places: 

• Tuesday, Oct. 24, 3-6:30 p.m.: Drop-in session at Sumner Station platform, 810 Maple Street.
• Tuesday, Oct. 31, 5-7 p.m.: Visit our table at Sumner's Street of Treats on Main Street (at the intersection with Kincaid Avenue, at Heritage Park).

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. Sound Transit is currently conducting a survey about the future of Sounder S Line service.
