and clean facility. The Pontiac Silverdome reopened in 2010 and hosted many events, including soccer matches, concerts, HBO championship boxing, monster truck shows and many more. The harsh Michigan weather eventually got the best of the aging venue, and in 2013 an excessive amount of snow caused a portion of the antiquated roof system to tear. The Pontiac Silverdome's roof issues dated back to the 1980s with a long list of weather related problems. The Pontiac Silverdome's uniqueness was also its downfall. As one of the last air supported football stadiums left, the inability to find a qualified company capable enough to repair the damaged roof, paired with the financial woes of the city, and the city's inability to pay for police, emergency services and road maintenance, the decision to close the facility for good was decided in 2013. The owners later auctioned the stadium's contents in 2014 and for a few years the parking lot was home to tens of thousands of recalled Volkswagen vehicles. In 2017, the Silverdome owner decided to tear down the closed facility. The upper ring of the stadium, which had supported the roof structure, was imploded on December 4, 2017, after a failed attempt the previous day. Following the implosion, the remains of the stadium were brought down in sections with hydraulic excavators, and the last free standing section was felled by late March 2018. In September 2019, it was announced that Amazon would develop the site. Former uses The Silverdome hosted the Detroit Lions of the NFL (1975–2001), the Detroit Pistons of the NBA (1978–1988), the Detroit Express (for both outdoor and indoor soccer) of the NASL (1978–1980), the Michigan Panthers of the USFL (1983–1984), college football's Cherry Bowl (1984–1985), the Motor City Bowl (1997–2001), the MHSAA football state finals (1976–2004) and four first-round games during soccer's 1994 FIFA World Cup. For the World Cup matches, a natural grass surface capable of growing inside the dome was developed and installed by a team from Michigan State University. This grass surface was laid upon wooden pallets atop the artificial turf that was usually used. It was the first time that World Cup games were played indoors. The Silverdome also hosted the 1979 NBA All-Star Game, Super Bowl XVI on January 24, 1982, and the 1988 and 1991 NCAA Division I men's basketball tournament Midwest Regionals and NCAA Men's Division I Indoor Track and Field
