Erroneous Florida State Road 30 signage on <a href="https://en.wikipedia.org/wiki/U.S._Route_98" class="extiw" title="en:U.S. Route 98">US 98</a> in <a href="https://en.wikipedia.org/wiki/Carabelle,_Florida" class="extiw" title="en:Carabelle, Florida">Carabelle, Florida</a>, USA, looking west from the Franklin County Road 379 intersection. FL-30 is a "hidden" or "secret" designation for US-98 for state bookkeeping purposes, and is not supposed to be signed.
