Interstate 35 in Texas (abbreviated I-35 or IH-35) 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.

In Texas, Interstate 35 runs for just over 407 miles (655 km),^[1] which does not include either the 85-mile (137-km) segment of Interstate 35W or the 97-mile (156-km) segment of Interstate 35E. Texas contains more miles of the overall length of Interstate 35 than any other state, almost one-third of the entire length.

In general, this article only describes Interstate 35; for Interstates 35E and 35W, see their respective articles.

Trucks are restricted from travel in the far left lane of I-35 in either direction throughout the San Antonio area. The restriction covers Bexar, Guadalupe, Comal, and Hays counties.^[2]

I-35 as an elevated freeway as it runs concurrent with I-10 in downtown San Antonio.

[edit] Austin

In Austin, Interstate 35 is named Interregional Highway. Through most of the greater Austin area, I-35 is six to eight lanes, dropping to four lanes north of Williamson county. It forms the eastern boundary of downtown Austin and also passes through the eastern side of the University of Texas campus. I-35 is co-located with U.S. Highway 290 through central Austin.

Trucks are restricted from travel in the far left lane of I-35 in either direction throughout the Austin area. The restriction covers Hays and Travis counties and most of Williamson county and ends north of Georgetown where I-35 is reduced to four lanes.^[3]

I-35 is split into two decks between 15th Street and Airport Boulevard, north of downtown Austin. Both the upper and lower decks are signed as I-35 and US 290, and they use a common set of exit numbers, with some exit numbers duplicated between the two decks. The upper deck lanes are express lanes, with no on- or off-ramps. Drivers wishing to exit between 15th Street and Airport Boulevard must use the lower deck.

The I-35 corridor between San Antonio and Austin is considered one of the most congested stretches of highway in the Interstate System. Much of this traffic is due to I-35 being considered one of the primary NAFTA corridors. Efforts to alleviate the congestion include the construction of State Highway 130, which when complete will form an I-35 bypass loop to the east of Austin, and the development of the Trans-Texas Corridor, which has a planned alignment that parallels I-35. Many local and regional governance organizations have on-going studies on other methods to improve mobility on I-35, which include such features as commuter rail lines and additional managed lanes.^[4]

[edit] Waco and Central Texas

In Waco, Interstate 35 is known as the Jack Kultgen Freeway. I-35 has six to eight lanes in Waco, and portions of I-35 between Waco and Hillsboro are currently being expanded from four to six lanes. It passes just to the west of the Baylor University campus.

Beginning in Waco and continuing up until just before the I-35E/I-35W split north of Hillsboro, I-35 is co-located with U.S. Highway 77.

[edit] Denton and North Texas

Just southwest of Denton, Interstate 35W and Interstate 35E join to reform Interstate 35, which then continues north to the Oklahoma border. The exit numbers on I-35 continue on from the last exit of Interstate 35E.

Just north of Denton, U.S. Highway 77 is co-located with Interstate 35 through to the Oklahoma border, although it is not signed as such.
