Oh ho, what do we have here?
The 2015-16 (remember, two-year) state transportation map won’t be out for a month and a half or so, but one change has already been made for the benefit of those who look online. It’s in section 11 of the segmented map, or of course in southwest Iowa in the big one.
A little “v2” in the lower-right corner of the map indicates there’s been a change, and it’s this one — the addition of the new US 34 four-lane into Nebraska. The interchange with US 75 is premature, because it’s only an intersection right now. No mileage has been added yet.
No other changes were made to the map, and IA 370 is still there as you can see. This could be the only map that shows 370 and new 34 at the same time. (Also, if you look closely, you can see the greater Pacific Junction metropolitan area.)
