ATLANTIC CITY — Gov. Chris Christie said at a groundbreaking ceremony Thursday the new Gateway Project under construction turns the corner on the state’s commitment to the city.

“We didn’t give up on Atlantic City,” he said. “We are back to celebrating it.”

He praised the public-private partnerships that made the 675,000-square-foot, $220 million project possible. It includes new headquarters for South Jersey Gas, plus a new residential campus for Stockton University that includes an academic building, housing for more than 500 students and a parking garage scheduled to open in fall 2018.
