NEW YORK — Midtown workers and shoppers are facing detours and closed businesses due to a manhole fire at 47th Street and Fifth Avenue here.

Streets have been cordoned off in the area while New York City firefighters are trying to contain the blaze.

The fire is taking place not far from the heart of Rockefeller Center, and near major retailers including Saks Fifth Avenue, Guess, H&M, Topshop, the Revlon salon, and Michael Kors.

NYFD officials evacuated about 75 people from 579 Fifth Avenue and shut down the power in the building after Friday morning’s fire caused by a few manhole covers not far from Rockefeller Center. No injuries were reported and the situation is now under control, a NYFD spokesman said. Workers at Saks and other nearby businesses found a smoky scene Friday morning where a fleet of emergency vehicles were in place. Having turned over the matter to ConEd, the last remaining fire truck just left the scene.

ConEd officials said 579 Fifth Avenue, which includes the offices of Bank Leumi USA, will remain closed, as will East 47th Street between Fifth Avenue and Madison Avenue, as repairs continue.

Megan Seuderi, an associate at the Guess store at 575 Fifth Avenue, said she and her colleagues were evacuated and the building’s elevators were shut down as a precaution. The store has just reopened with a handful of tourists shopping.
