"This feature allows us to change the images and offer our guests a unique experience," Climate Pledge Arena vice president of marketing Rosie Selle said.
Construction began in February of 2018 on the site of Seattle Center Coliseum, which was built for the 1962 World's Fair and renamed KeyArena in 1994. As part of the project, the 44-million-pound roof that covered KeyArena was preserved by suspending it with columns while 680,000 cubic yards of soil were removed underneath.
Capacity at the arena is 17,100 for hockey, 17,200 for concerts and 18,100 for basketball; it will also be home to the Seattle Storm of the WNBA. To reach those capacities, builders had to dig down 50 feet, and the result was a 740,000-square-foot building, almost twice the size of KeyArena.
