Neal summarizes the advances in transportation in the state. Early settlers arrived after an Atlantic voyage of seventy-five days. Wagons and boats took them farther inland, and later a road system developed. This was followed by the railroads and major highways and finally the airplane. Traveling on the Great Wagon Road from Pennsylvania to Salisbury in Rowan County took 24 days in the 1790s, then 13 hours by rail in the 1940s, 7 hours by car in the Interstate in the 1970s, and finally 4 by plane today.
