SAN FRANCISCO—The Golden State Warriors will break ground for their new Mission Bay arena in January, the San Francisco Business Times confirmed.

The actual building will not erect until the third-quarter of 2017, but demolition and excavation will begin in the New Year for the Chase Center, which will be located on Third and 16th Streets.

GSW Construction confirmed their plans to break ground in January to the Citizens Advisory Committee on December 8, 2016.

The city of San Francisco approved the project about a year ago and the first permits were approved in November 2016, despite objections from groups like the Mission Bay Alliance who are concerned the new arena will increase traffic in the region.

In November, a state appeals court upheld the city’s plans to build the Warriors’ new arena.

“We’re very pleased with the Court of Appeal’s thoughtful and comprehensive ruling. This event center is an important civic priority that has been thoroughly scrutinized and has won overwhelming support every step of the way,” said San Francisco City Attorney Dennis Herrera.

The Chase Center was designed by David Manica and will include over 18,000 seats, nearly 700,000 feet of office and retail spaces spanning 11 acres. The arena is expected to open for the 2019-2020 season.
