MONTCLAIR — A section of Bloomfield Avenue was expected to be closed to traffic for several hours due to a number of manhole explosions early Tuesday night, Verona police said.

Capt. Mitchell Stern said firefighters were dispatched around 5:30 p.m. on a report of the explosions, which did not result in any injuries. Bloomfield Avenue was closed in both directions between Pompton Avenue in Verona and South Mountain Avenue in Montclair, Stern said. An Essex County sheriff's officer was also diverting traffic on the westbound side of the avenue at Valley Road in Montclair, an NJ Advance Media reporter at the scene said.

PSEG workers were on scene trying to determine the cause of the explosions, Stern also said.
