Knox County Communications Manager Michael "Big Sexy" Grider just sent out a release, noting that Mayor Tim Burchett has closed down all county offices under his purview due to the hazardous road conditions. Those include, but aren't limited to, libraries, health department, parks and recreation, senior centers, solid waste. (That also means the Virtual Alzheimer's Tour set for this afternoon will be rescheduled.)
In addition, the Register of Deeds and the Law Director's Office also are closed today.
And, it's a safe bet, too, that the clerk's office is closed, but I'm not positive as no announcement has been made. You should probably call if you need to go down there (865-215-2385).
