When I stayed in Florida(Pensacola and Jacksonville). People would always say highway then the number. Or Interstate then the number. Never a name.
Old thread, but fun.
In Dallas:
- Two-digit interstate highways are said with no "the," but with the "I." For example, "I-35" and "I-20."
- Three-digit interstate highways are just the number, said with neither "the" nor "I." For example, "635" and "820." I-35 has a special case, however, when the west or east branch are discussed, in which case they drop the "I" and are referred to as "35E" and "35W."
- US and State highways are just the number as well. For example, "75" and "36" and "190."
- Some highways have names, again with no "the." For example, US 75 is also "Central Expressway," 635 is "LBJ," a portion of I-30 is "R L Thornton," a portion of I-35E is "Stemmons." The names are about as common as the numbers.
- The only highway preceded with "the" is "the Tollway."
From what I can tell these rules hold for most of Texas. The only people who I've noticed say things like "the 35" are California transplants.
