The break was reported at about 9:30 a.m. The Fire Department said part of the street was "buckling."
There were major traffic delays in the area as detours were set up. Needham Street is a main thoroughfare near Route 9 in the Newton Highlands.
Police said businesses on the street were closed. At about noon, police residents of the Avalon can access their residence by using Columbia Avenue.
