Information signs, to three distinct designs, were also placed at various locations on or near I-19 to advise motorists that the highway was signed in metric. Notwithstanding the metric legends, the signing plans were dimensioned entirely in feet and inches.

New signs were put into place between exit 99 (Ajo Way) and exit 101 (I-10) in 2004 after the completion of the new I-10/I-19 interchange.

I-19 is a very heavily traveled corridor in the Tucson metro area. The freeway is currently two lanes in both directions for most of its length, with the exception of the interchange with I-10 up until
Irvington Road, where it transitions to four lanes. Current plans call for widening from Irvington

I-19 had originally been signed as it was constructed, in a series of small signing contracts that used customary units. In 1980, ADOT awarded a single contract to install new signs which used metric units, to overlay customary-unit expressions on some existing signs with metric-unit expressions, to

In such cases, all the distances were given in meters with "meters" (written out in full, not "m") after each distance value. On distance signs in general, "km" or "meters" appeared on the same baseline and with the same letter height as the distance values, while advance guide signs were formatted

The Fixing
America's Surface Transportation Act, or FAST Act, formally designates Interstate 11 throughout Arizona. It states that the I-11 corridor will generally follow Interstate 19 from Nogales to Tucson, Interstate 10 from Tucson to Phoenix, and US 93 from Wickenburg to the Nevada state line.
762:
The expressions on advance guide signs were of the form "2 km" (1.2 mi) for distances over one kilometer (0.62 mi) and "500 m" (0.31 mi) for distances under one kilometer (0.62 mi), with no provision for fractional kilometrages. On advance guide signs, the metric unit

In 1999, ADOT awarded two contracts (administered as a single construction project) to renew the signs along the full length of I-19. The general approach toward metric signing differed from that taken in 1980. Explicit units were given not just on advance guide signs, but also on interchange
