According to Terry Brinkman, the Nebraska Department of Roads was constructing the Nebraska Expressway system. This expressway system included U.S. 81 from the Kansas state line to Norfolk, Nebraska, with work expanding U.S. 81 to four lanes between Interstates 70 and 80. U.S. 77 was also expanded to four lanes from Beatrice to Lincoln and points northward to Ceresco and Fremont. Four-laning plans for U.S. 75 extended northward from the Kansas border (Auburn) to Omaha. The options available include:
Use Interstate 135 beginning at Wichita and proceed north on this present route until Salina, Kansas, then follow U.S. 81 north to Concordia, Kansas. At that point, the corridor would curve northeasterly to enter Nebraska just south of Fairbury and proceed northeast to Beatrice. At Beatrice, the corridor would proceed northerly via U.S. 77 to Lincoln. The route would then proceed north of Lincoln following U.S. 77 through Fremont and north until it crosses the Missouri into Iowa. The corridor would terminate at Interstate 29 in Iowa in or near Sioux City. The route could be extended northeasterly via Iowa 60 into Minnesota if desired. This corridor would connect Sioux City to Lincoln, Wichita, Oklahoma City, Dallas-Fort Worth, Sioux Falls, Fargo, and Winnipeg.
Follow Option 1, but route the corridor directly north along U.S. 81 to meet Interstate 80, then continue with an at-grade expressway for the route north of Interstate 80. This route could continue north to Pierre, South Dakota, and Bismarck, North Dakota.
Beginning at Wichita proceed northeasterly on Interstate 35 to either U.S. 77 or Kansas Highway 177. Then follow either the U.S. 77 or State Highway 177 corridors north to Manhattan (or Junction City). Then proceed north of Interstate 70 following the U.S. 77 corridor north into Nebraska to Beatrice and Lincoln. From there the route would continue to follow U.S. 77 north to Fremont then on into the Sioux City area and terminate as it does in Option 1. This corridor would also connect Sioux City to Lincoln, Wichita, Oklahoma City, Dallas-Fort Worth, Sioux Falls, Fargo, and Winnipeg.
Follow U.S. 75 from Dallas north to Tulsa then north to Topeka and then north to Omaha where it would merge with Interstate 29 just north of Council Bluffs, Iowa. This route would directly connect Omaha, Sioux City, Sioux Falls, Fargo and Winnipeg to Topeka, Tulsa, Sherman, and Dallas/Ft Worth, but it would not serve Lincoln directly.
