PROVIDENCE — A gas main on Cushing Street broke last night, prompting the evacuation of a multifamily home on Hope Street, a National Grid spokeswoman said.

No one was injured and the residents of 250 Hope St. were able to return to their homes within two hours, spokeswoman Elise DelBarone said.

The police said they closed off seven intersections after the smell of natural gas became noticeable around Hope Street and Lloyd Avenue.

The smell was dissipating by about 10 p.m., Lt. Gerald DeLomba said.

Officials from National Grid, the Fire Department and other agencies were surveying the area, trying to locate the source of the gas smell, he said.
