The Twins, the Vikings, and the Gophers all proposed replacements for the Metrodome, and all three were accepted. The first of the three major tenants to move was the Gophers, who opened their new TCF Bank Stadium in September 2009. The next to depart were the Twins, whose new Target Field was completed in time for Opening Day 2010. On May 10, 2012, the Vikings were granted a new stadium by the Minnesota legislators that was built on the Metrodome site, which opened for the 2016 NFL season. Governor Mark Dayton signed the bill on May 14.
