Three states - Florida, Alabama, and Tennessee - have an unsigned state 
designation for every segment of U.S. Route (and Interstate in Florida). 
For example, Interstate 4 is also State Road 400, which appears on some 
maps but is not signed along I-4. But after I-4 ends at I-95 (SR 9), SR 
400 continues as a short signed route to the end at US 1 (SR 5).
