Tragedy has shaken the city, following two explosions that occurred at the Boston Marathon finish line on Monday that have left three dead and more than 130 injured. The City of Boston announced yesterday a crime scene perimeter has been established in the Back Bay, which has led to road, building and college closures.

All side streets along Boylston Street will be closed from Huntington Avenue to Newbury Street today, and likely for several days to follow. The City has provided the below map designating the crime scene and closures.

The MBTA is running, although Copley Station has been shut down until further notice. Boston Public Library’s Central Library in Copley Square is also closed today. The BPL notes on its Facebook page, all branch libraries will be open for their regular Tuesday hours, though.

The Prudential Center is open, but access is limited to the Huntington Avenue entrance. Retailers have been told they “can open at their discretion.” Due to street closures, stores and buildings along Boylston Street have been closed, however, and will be shut down indefinitely.

Following a fire at the JFK Library Monday afternoon, the JFK Library has announced they will not be open today. In conjunction, the UMass Boston campus is also closed, “as law enforcement officials continue to investigate yesterday’s incident at the JFK Library.”

Boston Public Schools are closed this week for spring recess, which spans from April 16 to 19. There have been other college closures, however, which include:

Berklee College of Music | Berklee has announced the College will be closed today. Administrators ask students that if they live in or near campus to “please stay away from the Copley area due to the ongoing investigation.”

Benjamin Franklin Institute of Tech | Located on Berkeley Street, the Benjamin Franklin Institute of Tech will be closed today “for the safety and comfort of students, faculty and staff.”

Boston Architectural College | The Boston Architectural College, located on Newbury Street, will be closed today, but Director of External and Government Relations Janet Oberto anticipates they will re-open on Wednesday. They have scheduled an all-school meeting at 10:00 a.m. Wednesday in Cascieri Hall “to share any news we have obtained, and to provide assistance and counseling to those who may seek those.” The College will also provide updates via email as they become available, as parts of the neighborhood are on lock down.

Emerson College | Emerson President Lee Pelton announced the College will be closed to provide “a day of healing and reflection.” Seven students were injured during yesterday’s events, but have been treated at a local hospital and released.

The City has warned people returning to work “will notice an increased police presence,” but that “they should not be alarmed.” Mayor Tom Menino has asked that anyone with concerns about their family members or friends who were at the race call his 24-Hour Hotline at 617-635-4500.
