Boston commuters should plan to avoid Revere and Charles Streets Friday morning as crews respond to a major water main break in the area.

Around 3:30 a.m. Friday morning, a water main broke at the intersection between Revere Street and Charles Street in Beacon Hill. A heavy stream of water rushed down Charles St. for nearly a third of a mile to Cambridge Street near the MGH T stop.

Water was still gushing as of 6 a.m. Friday morning. Boston Police have closed down the impacted streets as crews respond to the mess. It is unclear when the streets will re-open.
