    A pipe explosion in the Flatiron District shut down a heavy traffic and tourist area during Thursday's morning rush hour. And it may stay that way for days.

    The sudden explosion sent thick steam billowing over Manhattan and left a gaping hole in the middle of the street.

    The asbestos-lined 86-year-old steam pipe forced the evacuation of more than four dozen buildings amid "real concern" carcinogenic debris thrown stories high by the rupture could have gotten into people's buildings or air conditioners, Mayor Bill de Blasio said.

    The blast came almost exactly 11 years to the day of another Manhattan steam pipe blast.
