Looking north from the Four Meter telescope at SR 386 along the road up Kitt Peak. 07/04/08
Arizona State Route 386 travels from SR 86 up the side of Kitt Peak to Kitt Peak National Observatory. The road was added to the State Highway system in 1967, and completed that same year to allow construction of the 4 meter telescope. The roadway is similar to CR S-7 in San Diego County, California.
The original road to Kitt Peak was unpaved. It was used by the observatory from 1958 to 1967.
Arizona Route 386 followed a dirt road up Kitt Peak before shifting to the more gradual ascent of a paved route in 1967.
