A 150-foot-high section of stands being built at the University of Washington’s Husky Stadium collapsed, sending construction workers fleeing for their lives but causing no injuries.

The structure “went down like a corkscrew into a wine bottle,” said Dave Graden, an iron worker who was being lowered onto the section by a crane at the time.

Graden called it a miracle that he and a co-worker, Ray Hegath, in the crane bucket escaped injury.

The stadium expansion work, which began just after the last home football game Nov. 15, is part of a $12.9-million project to add 13,500 seats on the stadium’s north side.
