Letting off some steam on Election Night

Alex Mellion captured the scene at Congress and Hanover streets around 10:30 p.m., when a steam main burst, sending steam into the air and shutting the Haymarket T stop - which was re-opened in time for this morning's commute.

WBZ reports the explosion sent asbestos into the air and left Congress Street shut down.

Somebody who works in a building near the intersection reports the pipe had been leaking steam for a week.
