A major milestone for Cobb County! 🇺🇸
Yesterday, our partners at the Cobb Convention Center Atlanta celebrated the "Topping Out" of their $190 million expansion and renovation project — placing the final steel beam, adorned with an American flag and a tree (a Scandinavian tradition dating back over a thousand years!), atop the new structure.
Members of the Cobb-Marietta Coliseum & Exhibit Hall Authority, staff, and the Holder Construction team signed the beam before it was raised into place — signaling that the framework of this transformative project is nearing completion.
When complete in spring 2027, the expanded facility will offer:
- A new two-story grand entryway
- A 7,200 sq ft junior ballroom
- 11 new meeting rooms and an executive boardroom (24,000 sq ft of state-of-the-art meeting space)
- An 11,000 sq ft outdoor event courtyard and a separate garden, bringing natural light into interior conference spaces
- New connected parking with covered, all-weather access
- 13,000 additional sq ft of indoor event space
For Cobb County, this expansion represents more than square footage — it strengthens our position as a premier destination for conventions, corporate events, and economic activity across the Southeast.
The convention center remains open throughout 2026.
