The much-anticipated groundbreaking for the new Minnesota Vikings football stadium is being pushed out a bit longer. Officials involved in the $975-million facility are now eying a November start to significant construction. That’s slightly later than the tentative October schedule set earlier. The Vikings stadium project is churning along behind the scenes, however, with millions of dollars in contracts already inked. Yet to come are a lease with the team, a maximum construction price and a bond sale to pay for it. Meanwhile, a probe into the finances of the team’s New Jersey-based owners the Wilfs is underway. The examination is meant to ensure that the team’s $477-million private financial pledge will be met.
