A 12-inch water main ruptured early this morning in Roxbury and caused a car-sized sinkhole that forced the closure of a busy section of Tremont Street, police said.
The water main broke at about 4 a.m. near the intersection of Tremont and Cunard streets. Police closed Tremont Street between Melnea Cass Boulevard and Coventry Street and urged motorists to avoid the area.
Several buildings in the neighborhood lost water service because of the break, according to Thomas Bagley, spokesman for the Boston Water and Sewer Commission. Service was restored by about 12:15 p.m., but the road won't be patched and reopened until 8 or 9 p.m., he said.
