A manhole explosion reported earlier today had police in Cranford close several roads while repairs were made.
According to Cranford police, officers responded to the area of Springfield and North Union avenues for a report of a manhole explosion at around 2:30 p.m.
Upon arrival, police, firefighters, and PSE&G determined that the cause of the explosion was due to an underground network fire.
