Bunker Hill Bridge is the only surviving Haupt truss bridge in the U.S. and one of only two surviving covered bridges in North Carolina. Patented in 1839, the Haupt truss featured diagonal braces spanning multiple panels, which was an attempt to eliminate the cross-strain found in lattice truss bridges. Although it was almost immediately eclipsed by the Howe truss and never reached the mainstream of covered bridge building, the Haupt truss is of interest for its association with Gen.

 On 19 August, the AIAA Historic Aerospace Sites Committee dedicated Kitty Hawk, NC, as a historic aerospace site, following a decades-long negotiation with the U.S Park Service. A historic marker was unveiled at a 0930 hrs ceremony as part of the First Flight Society’s National Aviation Day at Kitty Hawk. At this site on 17 December 1903, Orville and Wilbur Wright achieved the first sustained, controlled heavier-than-air flight of an aircraft, opening a new era of transportation throughout the world.

The first authenticated discovery of gold in the U.S. occurred on the Cabarrus County farm of John Reed in 1799, sparking the nation's first gold rush. During its peak years, more than a million dollars of gold was recovered a year, making North Carolina a leader in gold production until 1848. This mill, built by the Mecklenburg Iron Works of Charlotte, North Carolina, is original except for the timber work. Two groups of five 750-pound stamps with 5- to 7-inch lift, rose and fell thirty-five times a minute to yield a finely crushed ore.

The Dorton Arena was the first use of a cable-supported roof system in the world. Commissioned in 1949 by North Carolina State Fair manager J.S. Dorton, the new building was intended to be a livestock judging pavilion. Architect Matthew Nowicki (1910 - 1950) proposed a structure that included a pair of intersecting parabolic arches supported by slender columns around its perimeter with a network of wire cables that supported the saddle-shaped roof.

In 1894, Catawba County, North Carolina commissioners asked local landowners to build and maintain an 85-foot-long bridge across Lyles Creek. The community hired Andy L. Ramsour, who served as keeper of the Horseford covered bridge over the Catawba River in Hickory, North Carolina.

The Atlantic Ocean's northward-flowing Gulf Stream meets the southward-flowing Labrador Current at a point marked approximately by North Carolina's Outer Banks. Since the earliest days of United States commerce, shifting tides, inclement weather, treacherous shoals, and a low-lying shoreline there contributed to what soon became known as the Graveyard of the Atlantic. Warning sailors of this danger quickly became a top priority in the integrated system of navigational aids provided by the federal government to promote safe passage along the Atlantic Coast.

A majority of the buildings, used originally in steam locomotive repair and maintenance, are still intact, including the backshop (erecting shop), roundhouse, flue shop, paint shop, and parts storage buildings. The 37-stall roundhouse is one of the largest remaining roundhouses in North America still in continuous operation. The site contains other significant buildings including the car repair shed, yard office, oil house, sand house, and wheel balancing shed.

The integration of pump and turbine was the first of many to be installed in power-plant systems in the United States. It was the largest and most powerful in the world. As a "pump storage" unit in the Tennessee Valley Authority's system, it effected significant economies in the generation of electrical energy. The unit was designed by engineers of the Tennessee Valley Authority and the Allis-Chalmers Company. It was built by Allis-Chalmers.

This run-of-the-river plant is a typical example of late nineteenth-century small-scale (750 kilowatt) low-head hydroelectric power technology. The Fries Manufacturing and Power Company began operating the Idol's Station on April 18, 1898, making it the first commercial hydroelectric plant in North Carolina involving long-distance power transmission, fourteen-miles distance at 10,000 volts. Idol's was an important power source for transportation, lighting, and industry in the Winston-Salem area.

In his search for a more economical way to make aluminum, Canadian inventor Thomas Leopold Willson accidentally discovered the first commercially viable process for making calcium carbide, which is used for production of acetylene gas, at a location in North Carolina. This chance discovery produced a series of products, from improved lighting in remote locations to the synthesis of a host of organic substances.
