Interstate 35 (abbreviated
I-35 or
IH-35) in Texas is a major north–south Interstate Highway running from
Laredo near the
United States-Mexico border 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 it splits into two auxiliary routes just north of
Hillsboro.
Interstate 35E heads northeast where it passes through
Dallas.
Interstate 35W turns northwest to run through
Fort Worth. The two branches meet up in
Denton to again form Interstate 35, where it continues to the Oklahoma border. The exit numbers for Interstate 35E maintain the sequence of exit numbers from the southern segment of Interstate 35, and the northern segment of Interstate 35 follows on from the sequence of exit numbers from Interstate 35E. Interstate 35W maintains its own sequence of exit numbers.
