State Route 86, similarly to SR 84, was also a shortcut to the loops of US 80 to get from Las Cruces, NM to San Diego, CA. The eastern portion of SR 86 was replaced with I-10. Now, SR 86 just runs from Why to Tucson.
Why's name derived from the Y intersection that used to exist for SR 85 and 86. The intersection is just a T intersection now.
SR 86 used to extend to BL 19 in Tucson, but that was decertified in 2003, so SR 86 was cut back to I-19.
