I've seen it happen before, but it this case the county GIS says the gravel road is a right-of-way down around both curves, but ends before the houses on the south.  I was the one who drew Valley Road on OSM 5 years ago, and at the time I marked the gravel section as highway=service + access=permissive (meaning it's not right-of-way but the owner isn't banning the public).  I've now split the gravel road into segments at the (alleged) right-of-way point, removed the access=permissive tag without adding access=yes on the (alleged) right-of-way portion of the road because we're not quite sure what's going on, and added explicit access=private on the part beyond the right-of-way.  Hopefully highway=service + access=private should be enough to prevent undue demands.
