All are invited to a groundbreaking event to help start the construction project to replace SeaTac’s Tyee High School with a new, modern high school building on Friday, Aug. 18, 2023.

The groundbreaking ceremony is scheduled to start at 3:15 p.m. on Aug. 18 at the old football field behind Tyee.

“Join district, school and city leaders, elected officials, and representatives of Friends of Tyee, Yes for Highline and our construction partners to dig the first shovels full of soil!” the district said.

Pieces of the wood stage flooring from the round cafeteria building will be available to attendees as a memento while supplies last.
