Please don't correct anything on OSM to match TIGER, which has many errors.  We are still correcting error from mass imports that happened 16 years ago.

Per the map-what-on-the-ground principle, we should try to find out what the sign says.  Bing Streetside, a source we are authorized to use, has a picture from 10 years ago.  Also the county confirms this to be Mountain Cove Drive.  Country records are usually accurate and reliable for this type of information.
