The Providence Street Fire Station is no more-at least as a fire station. Multiple sources say the long planned closing is set for either Thursday or Friday. According to a memo sent to City Council on Monday, Ladder 5 is moving to McKeon Road Fire Station this week, while Engine 12 is moving to the Franklin Street Fire Station. As planned, UMass will move ambulances to the station. Starting Friday, ambulances will park on the front apron; they will occupy the old firehouse once renovations are finished.
