The one quibble I have with the new byway signs is that "Loop" designations can be easy to miss traveling at highway speeds. If the loop ribbon had a different color, maybe the green or bluish-green that's on the "Iowa Byways" header, that would help a lot.

IA 37, which has been around since the creation of the Iowa highway system, started out as a Dunlap-to-Onawa route, and remained co-signed to Onawa until the late 1960s. That through routing is reflected in this intersection.

IA 175 closely follows the Maple River from Ida Grove to this intersection, near where the Maple flows into the Little Sioux.

The Loess Hills Scenic Byway sign should have a right arrow to signify its continuance with 175 - this was fixed when new Scenic Byway signs were erected:

There's no particular reason for there to be four towns on this sign, as convention would omit Dunlap, but this appears to be a relatively new sign. It could be because 37 just skirts Earling.

Not only are the signs in reverse order than usual and spread apart more than usual, they are also old and peeling.

This DOT-standard shield from when this road was part of IA 37 was over a quarter-century old at the time of the picture.

Unlike many county road intersections, the state road ahead is signed, although this is probably related to the fact that this used to be 37.

Old EAST End (May 27, 1931-July 12, 1971): Stop sign, Old US 59, Shelby County

This is a mile east of the above intersection. The old highway was never given a county road designation; it should be M30.

Old EAST End (July 12, 1971-1982ish): Ellen St., Irwin

On July 12, 1971, US 59 was shifted a mile west to bypass Harlan and Defiance. Almost a month later, the Highway Commission officially extended the IA 37 designation along IA 268 to Irwin. That means that instead of adding IA 268 shields to two miles of road and creating a common end at new 59, eight miles were re-signed as 37 instead. OK, whatever.

Then the extension to Irwin was removed as part of the Great Decommissioning, sort of. It doesn't appear on the 1981 map, which is why I never bothered to get a picture. I didn't even visit Irwin until 2014. But according to the official route description, it wasn't turned over until August 16, 1982, and in that case I need to get there again.
