Florida State Road 685
State Road 685 is mainly a north-south highway in Tampa, Florida. From Dale Mabry Highway in South Tampa, the route follows Henderson Boulevard northeasterly for roughly one mile to Kennedy Blvd/State [Road 60 (Florida)|SR 60]. The remainder of the route is unsigned, but the hidden designation follows Kennedy Boulevard eastward to U.S. [Route 41 Business (Tampa, Florida)|U.S. Route 41 Business], at which point it turns north and becomes that highway's secret designation for just over until the merge with US 41 near Lutz.
