The cables that supported the Metrodome's inflated roof for decades were severed on Sunday in the next step towards complete demolition of the 32-year-old sports facility. 

Here's a look from @JaneyKr, via Minnesota Public Radio

From the Vikings

"This Sunday, February 2, the Metrodome roof support cables will be severed, causing the final roof structure to fall to the stadium floor. The process will involve small demolition charges placed on the cables that will be detonated simultaneously. Mortenson Construction expects minimal disturbance in terms of noise, vibration and dust. For comparison, the detonation will have a slightly lower decibel level than the pyrotechnics used following a Vikings touchdown. The only real disturbance will be temporary street and sidewalk closures from 5:30-8:00 a.m., as no public access will be permitted within 250 feet of the Metrodome." 

General construction timeline: 

"December 2013 - Groundbreaking
January 2014 - Demolition of Metrodome/Concrete frame assembly begins
August 2014 - Steel installation begins
Fall 2015 - ETFE roof installation begins
End of 2015 - Stadium is fully enclosed with heating
July 2016 - New stadium opens"

The Vikings also plan on opening a new stadium "Preview Center" in early February. From the Minneapolis-St. Paul Business Journal, the Vikings will possess 27,000 square feet of an office buliding at 1010 7th St. S across from the stadium site in downtown Minneapolis that will hold some sales and marketing staffers as well as "a mock-up suite" of the $975 million structure. 

The Minnesota Sports Facilities Authority and Mortenson Construction will also lease space in the building.
