The DakotaDome is a 10,000-seat multi-purpose stadium on N. Dakota Street in Vermillion, South Dakota. Opened in 1979 for a cost of $8.2 million, it is home to the University of South Dakota Coyotes for numerous athletic events, including football, men's and women's swimming and diving, and track. The DakotaDome was also the home site for the NAIA school Briar Cliff University football team until 2017 located 25 miles to the southeast in Sioux City, Iowa. The DakotaDome hosts other events throughout the year, including the South Dakota high school football championships each November. In 2014 a proposal for a new basketball arena went through and construction began just south of the Dome. The new arena, the Sanford Coyote Sports Center, which seats 6,000, first opened for the 2016 women's volleyball season (NCAA women's volleyball is a fall sport, preceding the college basketball season).Formerly an air-supported structure, numerous roof collapses led to it being replaced by a $13.7 million steel roof in 2001.
