Phoenix Area Highways

[The Ghostbuster]

A Business 60 designation along old the old US 60 (and old US 70/80/89) alignment through Phoenix, Tempe, Mesa, and Apache Jct. was probably considered unnecessary. There was once a Business 10 in Phoenix: https://www.aaroads.com/interstate-guide/business/ir-010/#arizona, although it seems to have been decommissioned around the time the last segment of Interstate 10 was completed in 1990.

I sincerely hope ADOT plans repave the SanTan Freeway in Gilbert soon. The noise is just deafening.

IIRC, ADOT turned Van Buren St. (Phx), Mill Ave/Apache Blvd (Tempe), and Main St (Mesa) to their respective cities at the time.  It still maintains and signs US 60 on Grand Ave. northwest of I-17.  If ADOT doesn't maintain it, ADOT doesn't sign it. 

One gratuitous example:  Country Club Drive/Arizona Ave. through Mesa and Chandler, other than the interchange at US 60 and between the Loop 202 and McKellips Rd.  They are the only segments of AZ 87 still signed south of the 202 Red Mountain Fwy to the Pinal County line.  Yes, there are signs for AZ 87 for Arizona Ave. on the 202 Santan Fwy, but once you hit the off-ramps, there are none.  Arizona Ave. is not signed as 87 anywhere in Chandler, even though there are still a few ADOT mileposts on it between the county line and a couple miles north of the 202.
