Notes
Image:Metric Interstate 19.jpg
- 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.
- In Nogales, Arizona, the southern terminus of I-19 is adjacent to the international port of entry, and southbound travelers can continue into Nogales, Sonora and connect with the northern terminus of Mexico Federal 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]
