Developers officially broke ground on the South Bay Town Center project Wednesday morning, kicking off construction for the sprawling mixed-use complex adjacent to the existing South Bay Mall.

Mayor Martin J. Walsh joined the development group EDENS at the groundbreaking, according to a release.

Walsh, thanking EDENS, said in statement: “This project will bring a new vibrancy and energy to a once-vacant area in South Bay, and the benefits will not only be felt in Dorchester, but all across the city as people ock to this new destination. This project serves as a great example of the type of mixed-use and transit-oriented development that we are looking to bring to all corners of our city.”

EDENS will develop and manage 160,000 square feet of retail property, including “an exciting mix of restaurants and shops, a 12-screen luxury AMC Theatre with IMAX, a flagship Wahlburgers, and a 130-room hotel for Dorchester and the greater Boston area,” the group said in a release.

New residences, containing 475 new housing units in a mix of studio to three bedrooms, will include 62 affordable housing units. Developers highlighted residential amenities such as roof decks, a pool with cabanas ad grilling areas, and fitness facilities.

Throughout the project’s progress, developers committed to a number of community benefits. New traffic signals will be installed at three intersections and be connected with the city’s Advance Traffic Control System (ATCS). Video camera systems at intersections will allow for traffic flow adjustments and camera systems throughout the property will join GPS-based security monitoring.

Mark Wahlberg recorded a video for the groundbreaking the Transformers movie set in Detroit. “Wish I could be there for the development, but so excited for the new development of South Bay,” Wahlberg said. “Wahlburgers is coming to Dorchester. It’s gonna be amazing.”
