Construction Update
The redevelopment of Memorial Stadium is a legacy project to better serve the needs of future generations of SPS students and maximize its use for the community in new and different ways.
With the construction phase underway now through 2027 – led by construction partner Sellen Construction – we will provide regular project updates via this website, campus signage, digital alerts, and monthly project email updates available upon request at MemorialStadium@sellen.com. In addition, Seattle Center will continue to coordinate updates with partner/resident organizations and event partners, and will post construction alerts and signage on campus.
For a peek at the project, visit the viewing windows on Harrison Street, next to Artists at Play!
Construction Schedule
- Construction work hours are 6 a.m. - 4:30 p.m. on weekdays and 9 a.m. to 5 p.m. on weekends (if necessary) – with no construction on most holidays – in accordance with site logistics and permit approvals. This activity will result in noise from vacuum excavator trucks, saw cutting, core hole drilling, dump trucks, and other heavy equipment.
Upcoming Construction Activity & Neighborhood Impact Updates
- Demolition of the stadium structure is complete, with structural foundation work currently underway.
- Work to replace a Seattle Public Utilities (SPU) sewer main which runs beneath the stadium is currently underway.
- Vehicle access is at 5th Avenue & Republican Street into the delineated Seattle Public Schools’ parking lot.
- Construction vehicle traffic will shift to the north side of the SPS parking lot through February 2026 to accommodate sewer line replacement work. Sellen will have flaggers in place to control construction and public access.
- As part of the construction of a new Memorial Stadium, a number of trees within the construction zone have been removed. This work is a necessary and carefully planned part of the project and approved through the City’s permitting and environmental processes. Learn more about tree sustainability including tree preservation, tree replanting, tree offsets, and the new tree canopy as part of the new landscape design.
