ATLANTA – The Cobb-Marietta Coliseum & Exhibit Hall Authority, owner and operator of Cobb Galleria Centre, Georgia’s premier mid-size convention venue for tradeshows, meetings, and special events, has approved the funding for a transformational, $190 million renovation and expansion project. It is scheduled to break ground in the fall of 2025 andis expected to be completed in early 2027.
“Over the past two years, we have conducted multiple supporting studies alongside design, master planning, pre-construction analysis, and financial reviews,” said Charlie Beirne, General Manager and CEO. “With this groundwork laid, we are poised to hit the ground running.”
The renovation and expansion will happen in phases. While the convention center will be closed for the last four months of 2025, it will reopen for business in January 2026 in the exhibit halls and ballroom.
“Cobb Galleria Centre will be open throughout 2026 and will continue to host trade shows, expos, meetings, conventions, and social events in the exhibit halls and ballroom,” Beirne said.
The outside arrival area, new parking deck, and expanded meeting and event space are expected to remain in progress until early 2027.
