Grocery and movie theater reopen after Hurricane Irma, which hit in September 2017

Eighteen months after Hurricane Irma roared across the Florida Keys, two national chains have reopened their storefronts.

Winn-Dixie, which has been shuttered since the wake of Irma, which struck Sept. 10, 2017, doing its worst damage in Marathon and parts of the Lower Keys, held a grand reopening of all its stores on Wednesday. Key West was spared the agony of the Category 4 storm.

But Keyswide, 4 percent of the population, or about 3,000 people, has left since Irma, according to a report by the University of Florida.

The company remodeled its stores in Key West, 2778 N. Roosevelt Blvd., Tavernier, 92100 Overseas Highway, and Big Pine Key, 251 Key Deer Blvd., and held promotions as it reopened its Marathon location at 5585 Overseas Highway.

“Our valued customers and caring associates have been through a long journey of rebuilding together, and we are thrilled to debut our brand new Marathon Winn-Dixie,” said Anthony Hucker, president and CEO of Southeastern Grocers in a press release.

In Key West, the Regal Cinemas movie theater reopened on Thursday, promoting the Friday arrival of the “Dumbo” movie and the Thursday showings of “Captain Marvel” and “Us.”

“We are thrilled to unveil the theatre’s sleek, new look and invite guests to celebrate Regal Key West’s grand opening,” said Richard Grover, vice president of communications for Regal in a statement. “Key West has a vibrant entertainment scene, and we are excited to continue investing in such a great community.”

The reopening of the Regal features a complete remodeling, including an expanded concession menu.

Key West has only one other movie theater, the Tropic Cinema, which is a nonprofit and before Irma, known for showing art and independent films.
