Minneapolis residents who live in the eastern section of downtown can expect a very loud popping noise from the Metrodome Sunday morning.
Demolition of the 32-year-old stadium, after being halted earlier this week, will resume with “controlled explosive charges” bringing down the ring beam that is a key part of its roof structure.
It will happen in just four seconds at around 7:30 a.m., said Jenn Hathaway, spokeswoman for the Minnesota Sports Facilities Authority, the public body overseeing construction of the $1 billion Vikings stadium.
“Neighbors should be aware that there will be vibration, dust, and noise associated with the ignition of the charges and the demolition of the ring beam,” the MSFA said in a statement. In January, the team demolishing the Metrodome used explosives to snap the cable that suspended its fabric panel roof.
The Metrodome is being torn down to make room for a new stadium for the Minnesota Vikings.
Demolition work was halted Monday after a ring beam unexpectedly fell out of sequence. No one was injured and the debris fell within the demolition safety zone, so no passersby were at risk of injury.
After consulting with structural and demolition experts this week, the MSFA said the safest way to bring down the remaining portion of the ring beam would be with the “controlled explosives.”
Several streets near the Metrodome will be closed before the demolition. Along with 11th Av., 4th, 5th, and 6th Streets and Chicago Avenue (Kirby Puckett Place) will be closed beginning at 5:30 a.m. and will remain closed until an “all clear” signal has been given. That should be no later than 9 a.m., the MSFA said.
The Downtown East light rail station will be closed during this time frame, as well. MetroTransit buses will serve as alternate transportation to shuttle passengers between stations adjacent to the Metrodome.
Gawkers are discouraged. The authority said no public access will be permitted within 250 feet of the Metrodome.
