(July 1, 1920-October 16, 1926)

NORTH End: Minnesota state line, now US 218 at line, Mitchell County IA/Mower County MN

Facing south on 40 (5/19/04)

There is no reason to believe that 40's original end and 218's present end aren't the same place. For more pictures see the US 218 page.

SOUTH End: Keokuk, Lee County


Facing southeast, but heading south, on 40 (10/4/15)

Facing southeast, but heading south, on 40 (10/24/05)

IA 40 got to Keokuk for sure, but as mentioned at the top of the page, there's no way to know if 40 was signed with IA 20 heading out on what's now US 136. One argument in favor is the ridiculously redundant extension of US 161 to the Des Moines River in 1936 because of "confusion". If it didn't, the present south end of US 218 is the likely place.
