Metric Interstate Divides Arizonans

Distance along I-19 is measured in kilometers, just as it is in Mexico. That means highway markers advise that there are three kilometers until the next gas station, four until the next rest stop, seven until the next desert town.

The Arizona Department of Transportation says the 400 signs along the I-19’s 100 kilometers are too old and need to be replaced. The new signs, officials say, would be like all the others in the state and would indicate distance in miles. {snip}

Some who live along I-19 do not particularly care for the signs, saying they look foreign, are confusing and serve no purpose now that the United States has decided not to give an inch to the metric system.
