It was a miracle on East 75th Street.

A 4-year-old girl on her way to school on the Upper East Side escaped virtually unharmed this morning after she was struck by a wood plank during a scaffolding collapse.

Workers were removing scaffolding in front of a building at 130 East 75th Street near Park Ave. when a piece of wood fell and hit the child.

Rochelle Siskind, 39, said she was taking her daughter, Jessica, to school around 8 a.m. at Temple Israel on East 75th Street.

“I heard a loud bang and a plank was over her whole body,” she told The Post.

A shaken Siskind quickly came to her daughter’s aid.

“She was crying,” Siskind said of her daughter. “A bunch of people ran over to help. I picked her up and brought her into the school.”

The girl later underwent an exam and was found to only have suffered a bruise on her shoulder.

“It’s surreal,” Siskind said. “Thank God she’s fine. You just never know. That’s the problem with scaffolding in the city.”
