Interstate 35 (IH-35 or I-35) is a major 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. 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, I-69E, and I-69W in South Texas. In two stretches, both through twin cities, the highway splits into —at Dallas and at Saint Paul, Minnesota—and —at Fort Worth, Texas, and at 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.
