I'm not too sure about this section of Herndon Parkway being primary, especially considering it's not much different from the northeast/southeastern section. It does look like a bypass of Herndon and is even designated as a truck route, but in reality it serves more as a circular collector road and alternative connector between Old Ox Road and VA 228. I'm already skeptical about VA 228 being primary since it runs so closely to FCP without serving its own purpose like 657 and 602/608 do, but 228 does connect to the Herndon town center whereas FCP bypasses it. That aside, I think all of Herndon Parkway should remain secondary.
