US 169 Winterset IA to MN

With a few minutes of scanning on Google Maps I found two railways that 169 crosses on newish overpasses, and one where it passes under an old railway bridge (Fort Dodge). I don't see any height warnings in the streetview at Fort Dodge.

It's fairly easy to identify potential crossings on the maps when zoomed in enough. It's harder to keep track of the jogs in the highway numbering when zoomed in.

There are books and websites with low bridge warnings.

What are you worried about? Hills? Farm traffic? Corners? Boredom?

A sampling of Streetview images shows the kind of Iowa I expect - straight road with lots of farms and corn fields. It jogs right or left periodically. Looks smooth with limited shoulders. If you get behind a corn harvester you probably won't pass until it turns off into a field or farm yard.

Only concern is low under passes

US 169 is generally a good road in Iowa. It's all 2 lane road with a good lane width. The initial road through Madison County and Dallas County is small rolling hills and nice scenery. It flattens out as you head north of Des Moines (Adel). Expect realistic traffic speeds to be in the low 60's but there are lots of small towns with slow downs to ~25mph.
