Having a total length of just over 102 kilometers (63 mi), I-19 is the seventh-shortest primary (two-digit) Interstate Highway in the contiguous 48 states, where only I-87 (North Carolina), I-97, I-86 (Idaho), I-14, (Texas) I-11, (Nevada) and I-2 (Texas) are shorter.
While the highway is short, it is a very important corridor, serving as a fast route from Tucson and Phoenix (via I-10) to the Mexican border. The highway is a portion of the US section of the CANAMEX Corridor, a trade corridor that stretches north from Mexico across the US to the Canadian province of British Columbia.
