Just over a week before the Armory international art show was due to open in Manhattan, a city inspection has revealed that one of the two West Side piers that house the event is structurally unsound.

Organizers of the high-profile art fair, set to open on March 7, have decided to relocate most of its exhibitors from damaged Pier 92 to nearby Pier 90, where the show’s sister art fair, Volta, had been scheduled to run concurrently.

The Volta fair has been canceled for 2019, its organizers said.

“We all agreed that presenting the New York 2019 edition in an extremely modified status would be a disservice to our galleries, the artists or the visitors,” Amanda Coulson, Volta’s artistic director, said in a statement. All exhibitors will be reimbursed, she said.

“It’s been quite heartbreaking for us as well as for the galleries” that planned to exhibit at Volta, Ms. Coulson said in an interview. “It takes a good six months to plan for a fair at minimum,” she said. “Eleven days is just not enough time to produce another fair.”
