Bit by bit, the Bradley Center, the home of the Milwaukee Bucks for 30 years, is coming down, and one of the biggest bits, the steel roof, was demolished Sunday morning.

The small, perfectly timed explosions came off without a hitch at roughly 9 a.m., but they did send debris into the street and created a huge cloud of dust. The Bucks, whose new home is the $524 million Fiserv Forum, called the blast a success.

One well-known Wisconsin native admitted that the sight made him “weirdly emotional.”

“So many moments that shaped my love for sports were in that building,” the Texans' J.J. Watt tweeted. “Chasing the blimp trying to catch tickets, watching Ray Allen light it up, begging for pucks before Admirals games and getting to play there myself as a kid. So many memories.”

The plan called for most of the roof to collapse into the old arena and that’s what happened, with the crash, according to the Milwaukee Journal Sentinel, causing onlookers to feel the sidewalk shake.

“We were freaking out,” Katie Landry told the newspaper. “I have never seen anything like that before. I didn’t think it was going to be that high, big and loud."

The Bucks' new home opened over the summer, and demolition of the old place is scheduled to be completed this summer. Bringing down the roof will make it easier for workers to take it apart.
