Flames erupted on the Brooklyn Bridge as fireworks were being shot from it during Macy’s July 4 display over the East River.

Video shows a plume of smoke emerging from a flaming section of the bridge as fireworks soar and burst around it Saturday night. Two other sections also appeared to burn as the pyrotechnics were being shot from the span.

All the fires burned out after a minute, a Post reporter observed. It was not clear how much damage was done, if any.
