This study examines the feasibility of making a major financial investment in the improvement of U.S. 20 between Sioux City and Fort Dodge, Iowa. This 119-mile (191-km) highway segment of U.S. 20 currently includes 97 miles (156 km) of 2-lane highway and 22 miles (35 km) of 4-lane highway (on the west end near Sioux City and a short section near Holstein). This 119-mile (191-km) segment is predominantly rural in nature, and serves a region of Iowa that has not been economically prospering. Local business leaders and residents have long desired major improvements to this highway segment, not only because of the safety and travel efficiency implications, but also because of the belief that the highway, as mainly a two-lane facility, is retarding the corridor area's economic growth and well being. The study was divided into five sequential tasks: (A) Evaluation of Existing U.S. 20; (B) Improvement Alternatives, Costs and Traffic; (C) Screening of Alternative Candidate Improvements; (D) Economic Feasibility Analysis; and (E) Interpretation and Comparisons.
