Iowa State University is open and classes are in session today. Those considering travel to campus are urged to put safety first, taking into account road conditions in their area. CyRide is running. Facilities Planning & Management crews have continually been spreading sand & treating slippery walks since Sunday afternoon. The blowing snow may cause some areas that have been cleared to become slick once again, so please walk with care on campus. Officials urge faculty and supervisors to accommodate those who are unable to make it to campus.
