As was the case in 1980, the signing plans were dimensioned in feet and inches. However, a number of signs near the Valencia Road interchange were replaced or amended when it was converted from a partial cloverleaf to a single-point urban interchange in 2000. One of these signs has a fractional kilometrage greater than , rendered as "1500 m," while others use "m" rather than "meters" as the unit expression. Metric unit expressions on the advance guide signs installed or modified as part of this contract appear on the same baseline as the metric values, rather than on a raised baseline as on other I-19 advance guide signs. Again, the plans were dimensioned in feet and inches.
