City plans for connecting Miller Road between Pinnacle Peak and Happy Valley have been in place since at least 1991, when the roadway was included in the Circulation Element of the 1991 General Plan. The roadway was mapped to extend as far north as Dynamite Boulevard. The planned alignment moves northeasterly from the intersection of Miller Road/Happy Valley Road until it matches up with the Hayden Road (80th Street) alignment at Jomax Road.

The planned extension of Miller Road north of Pinnacle Peak Road was also included in the City Council-adopted 2008 Transportation Master Plan and the Council-adopted 2016 Transportation Master Plan. These long-time plans for Miller Road are the reason that the developer of the Pinnacle Reserve subdivision constructed a four-lane roadway from Parkview Lane to Happy Valley Road in 1997. These same plans are the reason that the new Paseo at Pinnacle Peak subdivision has recently widened Miller Road to four lanes between Pinnacle Peak Road and Adele Court.

In addition to the Council-approved planning documents discussed above, signage near the south and north banks of the Miller Road/Rawhide Wash intersection indicating the future connection of Miller Road between Pinnacle Peak and Happy Valley Roads has been in place for over 3 years. The City Council approved funding to initiate work on the connection of Miller Road across the Rawhide Wash. The funding package includes a 70 percent contribution from the Maricopa Association of Governments (MAG) through their Arterial Life Cycle Program which focuses on regionally significant roadway corridors.
