Travel and Safety

Whenever classes meet, pay attention to local weather and travel conditions if you commute from beyond the Cambridge and Boston area, and use your judgment regarding safe travel to campus.

See Campus Safety and the HUPD website for more information and tips on campus safety. In an emergency on campus, call (617) 495-1212, or use one of the blue light phones located at various outdoor campus locations, to reach the Harvard University Police Department (HUPD). 

If Cambridge institutes an emergency parking ban during a weather or other emergency, a notice will appear on the City of Cambridge website.
