Interstate 35 (IH-35 or I-35) is a north–south Interstate Highway in the central United States. I-35 stretches from Laredo, Texas, on the American-Mexican border to Duluth, Minnesota, at Minnesota Highway 61 (London Road) and 26th Avenue East.3 Many Interstate Highways formerly had splits or spurs indicated with suffixed letters (N/S/E/W), and I-35 was the only one that still had such divisions, before the recent opening of I-69C and I-69E in the Rio Grande Valley. In two stretches, both through twin cities, the highway splits into Interstate 35E (Dallas and Saint Paul, Minnesota) and Interstate 35W (Fort Worth, Texas and Minneapolis).
At 1,568 mi (2,523 km), Interstate 35 is the ninth-longest Interstate Highway following Interstate 94, and it is the third-longest north-south Interstate Highway, following Interstate 75 and Interstate 95. Even though the route is generally considered to be a border to border highway, this highway does not directly connect to either international border. I-35's southern terminus is a traffic signal in Laredo, Texas, just short of the Mexican-American border. Travelers going south can take one of two toll bridges across the Rio Grande and the Mexican border, either straight ahead into the Juarez-Lincoln International Bridge, or via Interstate 35 Business through downtown Laredo into the Gateway to the Americas International Bridge.
To the north, I-35 terminates in Duluth, Minnesota, with connections to Canada from the interstate's terminus via Minnesota Highway 61 to Grand Portage, or north to the border at International Falls, Minnesota via U.S. Route 53 in Duluth, but that route is more typically accessed from the south by Minnesota Highway 33 at Cloquet, Minnesota.
Interstate 35 northbound begins at an intersection (controlled by a stoplight) with Business Spur I-35 in Laredo, Texas, just north of the Rio Grande and the international border with Mexico. Through Webb, La Salle, and Frio Counties, it has a mostly north-northeastern course, turning more northeastly around Moore.4 It then cuts across the corners of Medina and Atascosa Counties before entering Bexar County and San Antonio.
Interstate 35 is named the Pan Am Expressway in San Antonio. There, it has brief concurrencies with both Interstate 10 and Interstate 410, and it serves as the northern terminus of Interstate 37. I-35 heads northward out of the city towards the state capital, Austin, Texas.
In Austin, Interstate 35 is the Interregional Highway.5 Throughout Austin, elevated express lanes were constructed on either side of the original freeway. Prior to this expansion, this section included an at-grade railroad crossing, which is extremely unusual for a freeway. From Austin, I-35 goes through Round Rock, Temple, and Waco. In Waco, I-35 is the Jack Kultgen Freeway. The campuses of the University of Texas and Baylor University are located adjacent to I-35.
I-35 then heads to Hillsboro, where it splits up into I-35W and I-35E and runs through the Dallas/Fort Worth area. The official mile markers 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 x35 loop. In Dallas, I-35 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.
In Oklahoma, I-35 runs from the Red River at the Texas border to the Kansas state line near Braman. It passes through or adjacent to many of the state's major cities. From south to north these cities include Ardmore, Pauls Valley, Purcell, Norman, Moore, Oklahoma City, Del City, Midwest City, Yukon, Edmond, El Reno, Guthrie, Stillwater, and Ponca City. In Downtown Oklahoma City, I-35 has a major junction with I-40 and spurs into I-235 through the north central inner city.
Between the Oklahoma state line and Emporia, I-35 is part of the Kansas Turnpike. This section of interstate serves Wichita and passes through the Flint Hills area. At Emporia, I-35 branches off on its own alignment. This free section of I-35 provides access to Ottawa before entering the Kansas City Metropolitan Area, where it serves Johnson County, and Kansas City, Kansas.
Of note on the route, at several points between Cassoday and Emporia in the Flint Hills dirt driveways that provide direct access without a ramp, for cattle trucks, may be found in either direction along the highway.
BETO Junction is a highway intersection in Coffey County, Kansas that is the intersection of U.S. Highway 75 and I-35. It derives its name from the four major cities nearest the intersection: Burlington, Emporia, Topeka, and Ottawa. It is located 16 miles (26 km) north of Burlington at exit 155. Historically, the intersection referred to as "BETO Junction" before I-35 was constructed was located on the old US 75 highway alignments 2 miles (3.2 km) south and 2 miles (3.2 km) east, near Waverly, Kansas.
I-35 enters Missouri two miles (3 km) southwest of Kansas City's Central Business District as a six-lane highway. After merging with Southwest Trafficway and Broadway, it becomes eight lanes and continues north to downtown Kansas City, where it serves as the west and north legs of the Downtown freeway loop. Along the north edge of the loop, I-35 joins with I-70 immediately west of Broadway and carries six lanes of traffic with a speed limit of 45 mph (72 km/h). Upon leaving the loop, Interstate 29 begins, concurrent with I-35. The two interstates cross the Missouri River together on the Bond Bridge.
After crossing the river, I-29 and I-35 split. I-35 heads north to Cameron, Missouri, and then continues northward to the Iowa state line.
In the southern sections of the state, I-35 is parallel to U.S. Route 69, for much of its course.
In Des Moines, I-35 has a 12-mile (19 km) overlap with I-80. The concurrency takes place northwest of the downtown district of the city. At exit 127 of I-80, the overlap turns east and terminates at exit 137 via an interchange with Interstate 235.
North of Des Moines, I-35 is mainly parallel with US 69, traversing a vast and rural area of Iowa.6
All of I-35 in the state of Minnesota from the Iowa state line to the city of Duluth is officially designated the Red Bull Highway, after the 34th Infantry (Red Bull) Division.
I-35 splits again into I-35W and I-35E in the Minneapolis/Saint Paul, Minnesota area. The mile- and exit-numbering sequence continues along I-35E. At one sharp turn in I-35W near the junction with I-94, it is advised to slow to 35 mph (55 km/h) (although many drivers are able to maintain the speed limit of 55 mph (90 km/h)). Additionally, it is not possible to go from westbound I-94 to northbound I-35W, from southbound I-35W to eastbound I-94, from eastbound I-94 to southbound I-35E, and from northbound I-35E to westbound I-94 without resorting to surface streets.
On I-35E in Minnesota between Minnesota Highway 5 and Interstate 94, in both directions, trucks weighing more than 9,000 lbs (4,082 kg) are banned from the freeway, and the speed limit drops to 45 mph (70 km/h) but it is rarely obeyed. This section was not completed until the late 1980s (although the route was cleared and graded earlier) due to opposition from the historic Crocus Hill neighborhood, which sits only a few hundred feet from the alignment. The four-lane alignment, "parkway" design was a compromise. The truck bypass for this section is signed on I-494 and I-694 to the east of Saint Paul.
I-35 has an interchange with I-535 / U.S. 53 in Duluth, Minnesota, known locally as the "Can of Worms". This junction features a pair of left exits from I-35, a stoplight, and lane drops over the I-35 bridge.8
The national northern terminus of I-35 is at an intersection in eastern Duluth. Driver's options include merging with London Road / Minnesota Highway 61 northbound; proceeding through the stop lights onto 26th Avenue East; or turning left onto London Road southbound.
Some sections of I-35 in Oklahoma City were already built in 1953, before the Interstate system was created.9 Through Norman, Oklahoma, the interstate opened in June 1959. In Moore, it opened in two parts: the northern half, connecting Moore to Oklahoma City, opened in January 1960. The southern half, linking it to Norman, was opened to traffic in June 1967.10
I-35 through Oklahoma largely parallels U.S. Route 77. This is in large part due to efforts of the towns of Wynnewood, Paoli, and Wayne, which fought to keep I-35 as close as possible to U.S. 77. This was successful due to a threat from Governor Henry Bellmon to build a toll road rather than I-35, and legislation preventing state funds for the interstate from being spent if it were more than 1-mile (1.6 km) from the U.S. route.11
The final segment of I-35 (as originally planned) to open was in north central Iowa, between Mason City and US 20 near Iowa Falls. This segment was delayed due to some controversy. Originally, I-35 was to follow the alignment of US 69 from Des Moines all the way to the Minnesota border. However, Mason City's business community lobbied for the route to be moved closer to their city. On September 1, 1965, the alignment was changed to instead parallel US 65 through northern Iowa, which brought the highway much closer to Mason City. This, however, created a long diagonal section through Wright and Franklin counties. Local farmers objected to their farms being bisected into triangular pieces, and resulting litigation delayed I-35 for several years. A November 1972 ruling rejected a lawsuit filed by the farmers, and the final segment of I-35 was allowed to proceed, eventually opening in 1975. One of the final pieces of the highway puzzle happened in Faribault, Minnesota. For approximately 25 years, Highway 35 actually went through the town and travelers had to deal with several traffic lights. In 1975, the highway went around Faribault where today a traveler actually has three exit choices for this southern Minnesota town.
The proposed Trans-Texas Corridor toll-road project includes one proposal (TTC-35) to primarily parallel I-35 from the Mexican border up to the Oklahoma border.13 There are major disagreements as to what impact this parallel route would have on I-35 in terms of traffic, maintenance, and commerce.
The Trans-Texas Corridor was first proposed by Texas Governor Rick Perry in 2002. It consists of a 1,200 foot (366 m) wide highway that also carries utilities such as electricity, petroleum and water as well as railway track and fiber-optic cables.14 In July 2007, U.S. Representative Duncan Hunter successfully offered an amendment to House Resolution 3074, the FY2008 Transportation Appropriations Act, prohibiting the use of federal funds for Department of Transportation participation in the activities of the Security and Prosperity Partnership of North America (SPP). Hunter stated that: "Unfortunately, very little is known about the NAFTA Super Highway. This amendment will provide Congress the opportunity to exercise oversight of the highway, which remains a subject of question and uncertainty, and ensure that our safety and security will not be compromised in order to promote the business interests of our neighbors."15 Fellow Republican Congressman and presidential candidate Ron Paul brought the issue to mainstream prominence during the December 2007 CNN-YouTube GOP debate, where he rejected the concept and also called it the NAFTA Superhighway after the North American Free Trade Agreement and, like Hunter, framed it within the ultimate goal of creating a North American Union.
