I work closely with the New Castle County and the other two counties in Delaware.  One of my responsibilities is to gather and conflate parcel, e911 address points and road data from each county into statewide datasets.  It was brought to my attention that OpenStreetMap shows the wrong street name for Clark Farm Road Smyrna, Delaware.  Our state data,  federal data,  county data, Bing maps and Google maps show this road as Clark Farm Rd.  Please see the following site maintained by New Castle County Delaware.  They are the authority for these data.  https://www.arcgis.com/apps/webappviewer/index.html?id=9752e5144c5f46248a3fdb6044f810b9&find=1502100192
