text: The gates are sometimes closed for the cold, presumably to prevent vehicles from carrying water onto the roads that ends up freezing. I don't know how exactly they decide to close or open them, but I guess it's based on current and forecased temps. Could also be partly based on the time of year; I'm not sure. I added that tag mainly to indicate it's sometimes closed.
  
  I'll email Campus Safety to ask for details.
  
  By the way, I would've replied sooner if you'd commented on the changeset where I added the tags with a link to this note since I don't usually check notes.
