The ownership groups of the Philadelphia 76ers and Flyers announced plans to build a new arena in South Philadelphia that would open in 2031.

The Philadelphia 76ers have decided not to build a $1.3 billion downtown arena, a surprising move that comes just weeks after the team received approval for the controversial project from the city council.

The Sixers had gotten approval for a controversial new arena Center City, on the border of Chinatown, but changed plans.
