[[File:Endofi35.jpg|thumb|right|I-35 starts at this [[traffic signal]] in Laredo, Texas]]

I-35 northbound begins at a traffic-signaled intersection with [[Interstate 35 Business (Laredo, Texas)|Bus. I-35-A]] in [[Laredo, Texas]], just north of the [[Rio Grande]] and the international border between [[Mexico]] and the US. It has a {{convert|17|mi|km|adj=on}} [[concurrency (road)|concurrency]] with [[U.S. Route 83 in Texas|US&nbsp;83]]. Through [[Webb County, Texas|Webb]], [[La Salle County, Texas|La Salle]], and [[Frio County, Texas|Frio]] counties, it has a mostly north-northeastern course, turning more northeasterly around [[Moore, Texas|Moore]].<ref name="txdot-map">{{cite map |title = Texas Official Travel Map |author = [[Texas Department of Transportation]] |publisher = Texas Department of Transportation |year = 2006 }}</ref> It then cuts across the corners of [[Medina County, Texas|Medina]] and [[Atascosa County, Texas|Atascosa]] counties before entering [[Bexar County, Texas|Bexar County]] and [[San Antonio]].

I-35 is named the [[Pan-American Highway|Pan Am Expressway]] in San Antonio. There, it has brief concurrencies with [[Interstate 10 in Texas|I-10]] (with it [[U.S. Route 87|US&nbsp;87]]) and [[Interstate 410|I-410]], and it serves as the northern terminus of [[Interstate 37|I-37]]. I-35 heads northeast out of the city toward the state capital, [[Austin, Texas|Austin]].

In Austin, I-35 is the Interregional Highway and has a concurrency with [[US 290]] through Downtown Austin.<ref name="about">{{cite web |last = Bear |first = Jacci Howard |url = http://austin.about.com/od/roadmaps/f/ih35.htm |title = Are Interstate Highway 35 and Interregional Highway 35 the Same Road? |work = About.com |access-date = December 7, 2006 |archive-url = https://web.archive.org/web/20081207201156/http://austin.about.com/od/roadmaps/f/ih35.htm |archive-date = December 7, 2008 }}</ref> Throughout Austin, elevated express lanes were constructed on either side of the original [[freeway]]. Prior to this expansion, this section included an [[Level crossing|at-grade railroad crossing]], which is extremely unusual for a freeway. From Austin, I-35 goes through [[Round Rock, Texas|Round Rock]], [[Temple, Texas|Temple]], [[Pflugerville, Texas|Pflugerville]], and [[Waco, Texas|Waco]]. In [[Belton, Texas|Belton]], south of Temple, it serves as the current eastern terminus for [[Interstate 14|I-14]]. In Waco, I-35 is known as the Jack Kultgen Freeway, and begins its concurrency with [[U.S. Route 77 in Texas|US&nbsp;77]]. The campuses of both the [[University of Texas at Austin]] and [[Baylor University]] are located adjacent to I-35.

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

After passing through Dallas and Fort Worth, I-35's two forks rejoin each other in Denton near the [[University of North Texas]] campus. The unified Interstate then continues north to [[Gainesville, Texas|Gainesville]] before crossing the [[Red River of the South|Red River]] into Oklahoma.
