I found State Highway 43 in IDAHO!

...and it's all of about 3.868 miles long!

It's not exactly in an area of the state I plan on visiting. I think a ride up to Missoula MT may be in order, there's a Highway 43 there that looks much more rider friendly!

Just where in Idaho is the lengthy stretch of road?

[Kfengler]

It runs south from Ucon ID, to E. Iona Rd.

Put this into Google Maps: ID-43, Bonneville, Idaho, United States

That's just a hoot and a holler from Montana 43 which runs between Divide and Wisdom, Montana and Gibbsonville, Idaho. :cool:
