About 60 people were evacuated from a Northeastern residence hall this morning after part of its external structure crumbled from the roof, sending several tons of debris falling six stories onto Huntington Avenue.

The collapse at 337 Huntington Ave. did not cause any injuries, said Boston Fire Department spokesperson Steve MacDonald. He said the building was evacuated because there was initial concern that the front of the structure might also be unstable, but said BFD officials no longer believed that to be the case.

Vice President of Marketing and Communications Mike Armini said the roof’s cornice — a cement trim that borders the roof and the outer wall of the building — collapsed at about 8:30 a.m. while a roofing company was replacing the roof.

Armini said Northeastern officials were waiting to hear from the Inspectional Services Department (ISD) later today about the cause of the collapse. He said he was not sure which roofing company was working on the roof.

ISD officials did not immediately return requests for comment.

MacDonald said the cornice was about 100 feet long and weighed several tons, and crashed to the sidewalk in one piece.

‘It’s an absolute miracle there were no people walking by,’ MacDonald said.

City officials closed Huntington Avenue between the Museum of Fine Arts and Massachussetts Avenue and interrupted MBTA service on the E branch of the Green Line following the collapse. MBTA service was restored by 11:30 a.m.

More than 100 public safety workers were at the scene, MacDonald said, including Boston police and fire, MBTA transit police and Northeastern Department of Public Safety officials.

Armini said the building’s residents, which are a mix of students taking summer classes and long-term non-student residents, were evacuated through the back door of the building.

‘Everything went according to plan,’ he said.

He said Northeastern officials are waiting to hear back from ISD about whether students will be able to move back into the building tonight. He said Northeastern is prepared to relocate students into on-campus housing if needed.
