The Lincoln Highway was the road that came before our Nebraska Interstate 80. It was the first official interstate and Transcontinental road across the United States. Today we recognize a similar route to this road as Interstate 80 which was completed across Nebraska in 1974. This newer Interstate 80 road covers over 450 miles of distance from East to West across Nebraska covering the most distance of the Interstate which travels from New York to California; 12 states in total.
