No idea what to name this small stretch of road. Was named (on OSM) County Line Road, signed as Haverford Road at Bryn Mawr Avenue and County Line Road at Landover Road int. It is on the county line, but MontCo addresses on this stretch of road are addressed to Haverford Road. Additionally, name_1 tag (while deprecated) is South County Line Road. No clear victor here to me.
