Texas
I-35 then heads to Hillsboro, where it splits into I-35W and I-35E and runs through the Dallas–Fort Worth area. The official milemarkers, along with the route of US 77, follow I-35E through Dallas—I-35W, which is 85 miles (137 km) in length, carries its own mileage from Hillsboro to Denton, as though it were an I-35 loop. In Dallas, I-35E is the R.L. Thornton Freeway south of I-30, which picks up the name heading east. North of I-30, it is the Stemmons Freeway.
