Target Center is the first arena to have a green roof. It was unveiled on September 15, 2009. In February 2011, the Timberwolves and the city of Minneapolis introduced a $155 million proposal to remodel the Target Center. Plans included shifting the main entrance to the corner of 6th Street and First Avenue, two large glass atriums, another restaurant, and a complete remodel of the interior. The plan was approved in 2012 by the Minnesota Legislature, as part of the bill that authorized a new stadium for the Minnesota Vikings.
