I-35 Exits in Texas

What to know about I-35 in Texas

• Exit numbers are mileposts. Exit 230 is about 230 miles from Laredo. Subtract two exit numbers to get the distance between them, which is the quickest way to answer "how far is the next exit" (more on that in How to Find the Next Exit From Your Location).
• The highway splits at Hillsboro. From exit 370 north, I-35E runs through Dallas and I-35W through Fort Worth; they rejoin at Denton around exit 467. Those two branches have their own exit numbers and are not on this page.
• Long rural stretches sit south of San Antonio. Between Laredo and Cotulla, and again from Cotulla to Pearsall, exits are 5 to 15 miles apart and several serve only ranch roads with nothing mapped nearby. Fill up in Laredo, Cotulla, Dilley or Pearsall rather than counting on the next exit.
• The Austin–San Antonio stretch is the busiest. From New Braunfels (exit 187) to Round Rock (exit 253) exits come every mile or two, most of them with multiple gas stations and restaurants, and the Buc-ee's stops at New Braunfels (exit 191) and Temple (exit 299) are landmarks in their own right.
• Rest areas and travel information centers. Texas keeps safety rest areas along I-35 and a Travel Information Center at Gainesville (exit 502) just before the Red River. They appear in the tables under "Rest area".
