MINNEAPOLIS (AP) -- It's another milestone in the demolition of the Metrodome. On Sunday, the cables that supported the facility's famous roof were severed as construction crews set off about a dozen explosive charges. Mortenson Construction said before the blasts that the noise would have a lower decibel level than pyrotechnics used after a Vikings touchdown.
Still, the noise prompted about a half-dozen calls to police from people who wondered what was going on. 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.
