UNION TOWNSHIP - A series of manhole explosions shut down several streets and prompted businesses to be evacuated in Union Township Saturday morning.

A stretch of road from the corner of Stuyvesant to Morris avenues was closed in all directions, with additional closures along Morris Avenue. 

The manhole explosions began early in the morning and ended just before noon. Officials say the explosions were caused by an electrical fire. PSE&G crews were on the scene for most of Saturday morning.

The town’s St. Patrick's Day parade was delayed, but did go on after the area was deemed safe. 

Authorities on the scene did not provide details on what sparked the electrical fire that caused the explosions. 

The incident was the second emergency involving manholes this week. On Tuesday, four exploding manholes sparked street closures and traffic diversions in Essex County.
