Let’s take a walk down memory lane, back to the long-forgotten era known as 2012. A high school football stadium in suburban Dallas with an eye-popping price tag — $60 million — opened up that August, drawing quite a bit of attention.

The stadium had 18,000 seats, a scoreboard with a 38-foot-wide high-definition screen and practice areas for golf and wrestling. It wasn’t the University of Oregon’s shiny new football facility, but it seemed to be as close as you could get in high school.

You already saw the headline, so you know where this is going: The school district announced Thursday that Eagle Stadium in Allen, Texas, would close indefinitely due to “extensive cracking” in the concourse as well as other potential structural problems.

“This is a significant investment for our community,” Beth Nicholas, the interim superintendent, said in a statement. “We are very disappointed and upset that these problems have arisen. It is unacceptable.”

The issue was first discovered the month the stadium opened and has only gotten worse, according to the Dallas Morning News.

Eagle Stadium will remain closed until at least June, when officials hope to have a better idea of the damage, the school district said. But it noted that repairs could be extensive and last for months, warning that the project would likely affect Eagles home games this fall.

The district hired an engineering firm to look into the cracking and other potential issues, and engineers found pervasive cracking during the early stages of its review. Even though there’s no official confirmation of problems outside the concourse, the stadium will remain closed during the review just to be safe, Louise Master, president of the school board, said in a statement.

Eagle Stadium is home to the Allen Eagles, who won back-to-back Class 5A Division I titles over the last two seasons.
