Candlestick Park
Plans were underway to construct a new 68,000-seat stadium at Candlestick Point. On November 8, 2006, however, the 49ers announced that they would abandon their search for a location in San Francisco and begin to pursue the idea of building a stadium in Santa Clara. As a result, San Francisco withdrew its bid for the 2016 Olympics on November 13, 2006, as its centerpiece stadium was lost. Groundbreaking for the Santa Clara stadium occurred on April 19, 2012. On May 8, 2013, the media announced that the name of the new stadium would be Levi's Stadium. The stadium opened on July 17, 2014, in time for the 2014 NFL season. The 49ers christened their new home a month after it opened.
Multi-purpose stadium
The Miami Marlins, which changed their name from the original Florida Marlins in November 2011, moved to Marlins Park, a new retractable-roof stadium in Miami, in 2012. Sun Life Stadium (now Hard Rock Stadium) was then renovated to eliminate its baseball functionality, making it a football-only stadium. With the Marlins' relocation, the Oakland Athletics are the last team in the U.S. still sharing a stadium with an NFL team (the Oakland Raiders), the Oakland Coliseum. This arrangement will end once the Raiders move to Las Vegas (most likely in 2020), after which each NFL and MLB franchise will have its own stadium. The Athletics are currently seeking a new home; they are currently exploring plans to build Oakland Ballpark. Before announcing their upcoming move to Las Vegas, the Raiders suggested a move back to Los Angeles, where they played from 1982 to 1994, and also actively explored a move to the Alamodome in San Antonio; other parties suggested that the Raiders share the new Levi's Stadium in Santa Clara with the 49ers.
