It's another milestone in the demolition of the Metrodome.
On Sunday, the 3.5-inch steel cables that supported the facility's famous roof were severed as construction crews set off about 42 explosive charges around 7:30 a.m.
The general public was not informed in advance, but nearby Hennepin County Medical Center hospital staff were given advance notice.
According to the Minnesota Sports Facilities Authority, once the cables and remnants of the dome have been removed, crews will be ready to begin tearing down the concrete bowl portion of the structure.
The Metrodome is being torn down to make way for a new $1 billion Vikings stadium. Steel installation for the new stadium is expected to begin in August.
