Cables supporting the roof of the Minnesota Vikings' former Metrodome have been blown up, as part of gradual demolition process.

The Hubert H Humphrey Metrodome was home to the Minnesota Twins from 1982 - 2008 and the Minnesota Vikings from 1982 - 2013.

It is being replaced by a new stadium for the Vikings.
