Residential and unclassified are rendered identically. I've never seen 
this particular bug - usually it's text like this but at least placed 
properly. Residential does look accurate, given the dead-end, but I'd 
also consider tertiary due to the centerline.

Is CR 9 actually signed, or is it just an internal designation used by 
the county? If the latter, unsigned_ref might be a better choice.
