MPR News reports Mortnenson Construction will cut the power to the Metrodome on Jan. 18, and the dome will start deflating immediately.
Mortenson vice president John Wood said the company plans to cut the Teflon roof fabric into small pieces for possible recycling, and to also recycle its steel cables.
The Pioneer Press says Mortenson, which will construct the new stadium, has begun preliminary work at the site.
It was almost exactly three years ago that the dome deflated unintentionally after a heavy snowfall, according to WCCO.
The Metrodome roof also deflated in 1981,1982 and 1983, each time because of tears from heavy snow. A small tear also briefly delayed a Twins game in 1986.
