Interstate 35 (I-35[a]) is a major north–south Interstate Highway that runs from Laredo, Texas near the Mexican border to Duluth, Minnesota. In Texas, the highway begins in Laredo and runs north to the Red River north of Gainesville, where it crosses into Oklahoma. Along its route, it passes through the cities of San Antonio, Austin, and Waco before splitting into two branch routes just north of Hillsboro: I-35E heads northeast through Dallas, while I-35W turns northwest to run through Fort Worth. The two branches rejoin in Denton to again form I-35, which continues to the Oklahoma state line. The exit numbers for I-35E maintain the sequence of exit numbers from the southern segment of I-35, and the northern segment of I-35 follows on from the sequence of exit numbers from I-35E. I-35W maintains its own sequence of exit numbers.
In Texas, I-35 runs for just over 503 miles (810 km),[1] which does not include the 85-mile (137 km) segment of I-35W. It does include the 97-mile (156 km) segment of I-35E. Texas contains more miles of the overall length of I-35 than any other state, almost one-third of the entire length.
The Interstate is currently undergoing an extensive renovation and expansion project, known as 'My35'. The project includes work on portions of the Interstate from Dallas south to Laredo. Once complete, the highway will span three lanes in each direction from Hillsboro to San Antonio.
