Interstate 35 runs the length of Texas, from the Mexican border at Laredo to the Red River above Gainesville, through San Antonio, Austin, Waco and the Dallas–Fort Worth metroplex. Between Hillsboro and Denton it splits in two — I-35E through Dallas, I-35W through Fort Worth — and the map here follows the I-35E side. The weather changes completely along it: flash flooding in the Hill Country, ice storms in the north.
