Road closures, vibration, dust and noise hit downtown Minneapolis Sunday morning due to the demolition of the Metrodome’s final ring beam.
WDIO sister station KSTP reports that the concrete ring beam came down with use of controlled explosive charges. Structural and demolition experts revised the original demolition plan after a section of the ring beam collapsed on Monday out of sequence.
The team determined that explosives were the safest way to demolish the last portion of the beam. "It was a complete success, it's laying on the ground, that's mission accomplished," said John Wood, Senior Vice President, Mortenson Construction.
Now that the dust has settled, Mortenson Construction is working to come up with a back-up plan to demolish the rest of the dome. "We think this will be the last use of explosives in the demolition process, from this point forward it should be a pretty conventional approach," said Wood.
The ring beam and corners of the Metrodome were brought down with 84 charges of dynamite set in 24 columns of the upper concourse, according to the Minnesota Sports Facilities Authority.
Neighbors experienced vibration, dust, and noise during and after the explosion, but experts said debris fell within the safety zone. The public was kept away from the area 250 feet from the Metrodome during the explosion.
It took 11 seconds to go down, knowing it'll take two years to put the replacement stadium up.
Mortenson Construction says they are still on schedule, and even though they need to come up with a new plan, the process is not delayed. They expect the entirety of the Metrodome will be gone by the end of April.
The new stadium, which will be the home to the Minnesota Vikings and many high school and college sporting and community events, remains on schedule to open in July of 2016.
