Interstate
19 (I-19) is a north-south Interstate Highway located entirely within the
state of Arizona.
I-19
is unique among U.S. Interstates because signed distances are given in meters
(hundreds or thousands as distance-to-exit indicators) or kilometers (as
distance-to-destination indicators) and not miles. According to the
Arizona Department of Transportation, metric signs were originally placed
because of the push toward the metric system in the United States at the time
of the original construction of the highway.
