Arizona 386

This map shows the original route (in brown) of the dirt road up Kitt Peak, and the 1967 route of Arizona 386. Notice the longer, more gradual ascent of the paved road.

Arizona 386 travels from Arizona 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 (similar to County Route S-7 in San Diego County).

The original road up Kitt Peak was a dirt road, used by the observatory from 1958 to 1967.

The highway is closed between 4 PM and 9 AM nightly due to the observatory.
