Road building held a low priority in North Carolina until the beginning of the 20th-century. At that time the state was not involved. It was left to the counties, and the counties did not work together. Therefore, crossing county lines would often provide a different type of road for drivers. The implementation of Rural Free Delivery (RFD), the North Carolina Good Roads Association, and the affordable Model T Ford made road construction a necessity. During the 1920s, through the efforts of Governors Locke Craig and Cameron Morrison and State Highway Commission Chairman, Frank Page, the state became nationally known for its outstanding highway system.
