NEW ORLEANS (AP) — Superdome officials say positive COVID-19 tests have come back for 32 workers contracted to perform renovations at the stadium in New Orleans.

A statement released by the Louisiana Stadium and Exposition District on Tuesday says affected workers have been “isolated away from the job site.” The state-owned Superdome currently is undergoing $450 million in renovations that have been deemed essential by Gov. John Bel Edwards.

The dome is slated to host the NCAA men’s basketball Final Four in 2022 and the Super Bowl in 2024.
