Traveling from Omaha through Lincoln, you might want to consider using the interstate as either of those will run you right through downtown area of those cities. West of Lincoln, depending on where your ultimate destination, you probably would want to stay on Hwy 6 (south of I-80) until it joins with Hwy 34 in Hastings. For the most part, pretty decent roads. Haven't driven them too much lately, but grew up in that area and drove them frequently.
