Goodbye Metrodome

"Mission Accomplished."  That's how a spokesman for Mortenson Construction assessed the demolition of the Metrodome's last remaining ring beam.  

The beam was taken down yesterday morning with a series of controlled explosive charges.  It took 84 charges of dynamite set in 24 columns of the upper concourse to bring the beam down.  The Metrodome is going away to make room for a new Vikings stadium.
