BOSTON (WHDH) - City crews are working to repair a broken pipe in Boston Monday morning that flooded several streets after a deep freeze gripped the region over the weekend.

The pipe burst at Congress and Sudbury Streets, sending water gushing onto Congress Street behind Boston’s City Hall.

Boston Water officials say it may not have been a water main as previously thought, but rather a fire hydrant lateral pipe.

The burst pipe is just one of many throughout the region as brutally cold weather has caused a headache for home and property owners.

Inside Boston Sports Club just a few blocks away, the cold took its toll on the plumbing. And at Boston Medical Center, one mother received a call that her son was being moved out of the NIC-U after a flood inside the hospital.

The hospital had to move 15 patients to different rooms, and six expectant mothers went to different hospitals.

Nobody was hurt, and cleanup is underway at the hospital.

In Brockton, a sprinkler burst after days of frigid temperatures. And in Manchester, New Hampshire, big water problems forced some residents out of their homes — a total of 45 people were impacted.

Congress Street in Boston is expected to be closed throughout the day on Monday as crews work to make repairs.
