Chemicals from the Coal Facility of Eastman Chemical Company was the first in the United States to use coal rather than petroleum as a raw material in the commercial production of acetyl chemicals — important building blocks in the synthesis of a wide range of consumer products. The plant, located in Kingsport, Tennessee, began operation in 1983 after more than a decade of planning and construction, prompted by the oil embargoes of the 1970s.
The Tennessee State Capitol, the first and only home of the Tennessee General Assembly, was designed by engineer and architect William Strickland. Since its construction, it has ably served, with little modification, as the seat of Tennessee's government.
Norris Dam impounds the Clinch River, a mountain tributary of the Tennessee River. The facility stands as a tribute and symbol of the birth of the Tennessee Valley Authority (TVA). Given broad jurisdiction over resource development in the watershed (a 40,000-square-mile basin comprising parts of Virginia, North Carolina, Georgia, Alabama, Mississippi, Kentucky, and Tennessee), the TVA was formed to plan for flood control, improve navigation, and produce hydroelectric power.
The Memphis Bridge (now called the Frisco Bridge) comprises three spans across the Mississippi River. With a main span measuring over 790 feet, it was one of the longest railroad bridges in the world upon completion. The renowned George Morison, after whom the bridge is unofficially named, served as Chief Engineer.
At the mountain where the Civil War's Battle Above the Clouds was waged, tourist business has thrived from the building of its first toll road (Whiteside Pike) in 1857 to present day.
Montogomery Bell was a land developer and iron maker who purchased the Harpeth Narrows site to expand his industrial empire - which ultimately consisted of 14 iron blast furnaces throughout middle Tennessee.
The Harpeth River makes a tight bend around a steep limestone ridge, losing 17 feet of elevation in a run of 5 1/2 miles. Bell excavated a tunnel through the limestone ridge, creating a shortcut for the river. The hydropower derived from this drop in elevation was used to drive the Patterson Iron Works built by Bell.
