Built along the pathway of the Great Platte River Road, I-80 in Nebraska follows the same route as many historic trails, including the Oregon Trail, the California Trail, and the Mormon Trail. Starting in 1957 after federal funding was allotted, Nebraskans began planning their Interstate construction. Led by the Nebraska State Highway Commission, there were hearings across the state to decide where the route was going to be. Aside from the federally mandated "control points" in Omaha and Scottsbluff, the route could vary across the state. Dozens of meetings were held in Grand Island, Kearney, and North Platte, among other locations. The commission addressed issues of whether the highway would be north or south of the Platte River or whether it would follow U.S. Highway 30. The South Platte Chamber of Commerce and various cities were very active in these sessions, and debate over where the Interstate would be constructed continued into the 1960s.
