EUGENE — The University of Oregon unveiled its vision of a new Hayward Field on Tuesday, a 12,900-seat venue the school is boasting will be “the finest track and field facility in the world.”

The project, which will involve a complete teardown of the current structures — including the 99-year-old east grandstand — will begin construction in June and will be finished in time for the Ducks to host spring meets in 2020, according to the school.

It will include what Oregon describes as state-of-the-art locker rooms, practice spaces and athletic medicine rooms, as well as a tower building that will be the tallest structure on the university campus. In addition, students and researchers in the UO’s human physiology department will be provided new laboratory and classroom spaces.

The school said the facility is being funded by gifts from Nike co-founder Phil Knight, his wife, Penny, and more than 50 other donors. Neither Knight was on hand Tuesday during the unveiling ceremony.

No estimated cost of the project was released.

Artist renderings of the new facility show a horseshoe design with a lower bowl that circles the entire stadium and an upper bowl that is open on the northeastern corner and much of the stadium’s north side.

The facility will use temporary seating to expand capacity to 30,000 in 2021 to get Hayward Field up to minimum standards for the IAAF World Outdoor Track & Field Championships.

Current capacity is listed as 10,500, though a seat count reveals the number to be closer to 8,500.

Outside the stadium will sit the nine-story, 165-foot-tall Bowerman Tower, named in honor of longtime coach and Nike co-founder Bill Bowerman and shaped to resemble an Olympic torch.
