Perhaps laying a bed of rocks next to a big glass house wasn't the best idea.
On Wednesday morning, stadium officials — and pedestrians, as well as passersby in cars, trains and buses — could see a broken window at ground level of the newly completed, not-yet-open U.S. Bank Stadium.
And it's going to remain broken for a while.
It's likely to take six to eight weeks to receive and install a new pane because the glass is custom to the building, according to a source with knowledge of the situation.
The break leaves the building in less-than-perfect condition for the ribbon-cutting Friday in which hundreds will fill the field to watch dignitaries congratulate each other about the $1.1 billion building that was the largest public-private effort in state history. According to the source, the glass was broken by someone walking along the north side of the building who picked up a rock and threw it at the ground-level wall of glass.
"They got it on the security camera," the person said.
An exterior pane, about 10 feet by 5 feet, shattered, leaving a hole big enough for a small human to crawl through.
A second interior pane prevents an opening in the facade.
