May 28, 2006 (eight[!] years ago tomorrow): North side of Northwood on US 65
Jason Hancock took a long trip in northern and northwestern Iowa on Memorial Day weekend to finish clinching every highway in the state. He mentioned that the mileage sign leaving Northwood, above, has been replaced with a Clearview version that uses the two-letter postal abbreviation for the cities. This is not the first appearance of that in the state, but/and it is widespread enough now that it’s almost certainly a permanent style change.
Note also that the sign, and its replacement, still include Faribault on the bottom line, even though US 65 now ends in Albert Lea. I believe it is the northernmost destination on a non-interstate sign (since the Twin Cities are all over I-35). Northwood is closer to Faribault than Iowa Falls, and just over 100 miles from the Minnesota State Capitol.
