I have informed you before to please not use Google Maps for mapping in OpenStreetMap. OSM as a free open-source project cannot use this data due to legal restrictions. Please see here: https://wiki.openstreetmap.org/wiki/Google

As for the road's name, the county's GIS shows that the road's official name is E. North Belt Road and that the businesses along it are addressed to the road. It is likely that at the time of the image capture you viewed was before the official name change or before the signs were updated. The on-the-ground rule typically applies but should be taken with a grain of salt in the prospect of road signs as they can be outdated or outright incorrect occasionally.
