Wikipedia Overview

U.S. Highway 30 (US 30) is part of the United States Numbered Highway System that runs for 3,112 miles (5,008 km) from Astoria, Oregon, to Atlantic City, New Jersey. Within the state of Nebraska, it is a state highway that travels 451.74 miles (727.01 km) west to east across the state from the Wyoming state line west of Bushnell to the Missouri River in Blair on the Iowa state line. Despite not intersecting Interstate 80 (I-80) even once, much of its length until Grand Island is closely parallel with the Interstate, not being more than one or two miles away. For most of its route, US 30 travels within the Platte River valley, adjacent to or near the river between Brule and Fremont, a distance of just over 300 miles (480 km). This corridor was also highly traveled during westward expansion along the California and Oregon trails, it was also used by the Pony Express and first transcontinental railroad. The landscape is dominated by vast agricultural fields within the fertile Platte River valley across the center of the state, while the western portion passes through higher plains and the eastern portion through the rolling hills adjacent to the Missouri River valley.
