June 15, 2004: South end of IA 86 in Milford. I-90 is 23 miles north.
Because 86 north of IA 9 wasn’t a state highway until 30 years ago, it has no shoulder and a wicked pair of curves at the state line. Iowa plans on fixing that in 2013 (PDF).
My options for this number were limited. There is no US 86, and the interstates at either end of the country are among the few two-digit routes I haven’t traveled.
