NE Iowa to Edinburg, Tx

Randy, you have one of two choices, I-35 or small towns along another route. I like the slower pace of the small towns. It all depends on how fast you want to get to the Valley.

We have taken I-35 from DFW area to Georgetown (just north of Austin) four times in the last 2 months. No slow downs or delays at all. Much of the pavement in the construction areas is newly poured concrete. And even the lesser parts with old pavement were generally smooth. Traffic running at or above posted limits.

I think the only time there is a problem is if you are unfortunate enough to encounter an accident, or to pass thru when they are doing new lane shifts as construction starts/completes or when they are setting beams over a new overpass or putting up new overhead signs in the construction areas.

I don't care for going thru a multitude of small towns either.

Getting through fort worth on 35 is a bit of a mess due to the construction. lane shifts, potholes galore, and brake checking knotheads. But depending on the time of day, it can be done in about 30 minutes if you are driving straight thru

I dont like I-35 in Texas. Go west of Fort Worth and hit 281 down to the San Antonio area. Its a good road.
