Notes
- Interstate 19 is unique amongst US Interstates, because signed distances are given in kilometers, and not miles. Speed limit signs give speeds in miles-per-hour, however. According to the Arizona Department of Transportation, metric signage was originally placed because of the "metric system push" in the United States at the time of the original construction of the highway. Infrequently, re-signing the highway to miles is discussed, but the costs involved would be too high for a rural Interstate such as I-19.
- I-17 and I-19 could eventually join to become one longer interstate which would be renamed I-21.
- Nogales, Mexico is the only town on the U.S. - Mexico border, to have the same name as its U.S. counterpart. From the Arizona town to the Mexican one, I-19 becomes Mexico Highway 15.
- A recent reconstruction project at the Interstate's northern terminus with Interstate 10 in Tucson, Arizona (at the interchange commonly called "The Crossing") was begun in 2002 and completed in late 2004. [1] (http://web.archive.org/web/*/http://www.1019crossing.com/)
