History
In 1979, NC 143 was established as a new primary route between Robbinsville and Stecoah, on already existing roads. Topography maps of Graham County in the early 1990s show an incomplete Cherohala Skyway already numbered as NC 143; however, this was not official until October 12, 1996, when NC 143 was extended to a completed Cherohala Skyway and its current western terminus at the Tennessee state line. The Cherohala Skyway segment dates earlier than NC 143, but was not completed until 1996 with a total cost of $100 million over the whole 34 years of construction.
Future
