This is another example of "what could have been" in the US Highway System; like the US 37 proposal between Chattanooga, TN and Sellersburg, IN. Or the US 59 proposal between the Minnesota/Iowa state line south of Ostrander, MN (or possibly from Oskaloosa, IA) to Lake City, MN (this US 59 would have aligned with the grid perfectly, unlike existing US 59). Or US 143 from Jackson, TN to Glasgow, KY. Or any of the other US Highways that had extensions proposed and rejected. Oh what a world this would be.
