Doe River (Elizabethton) Bridge
Main Category: CivilSub Category: BridgesEra: 1880-1889DateCreated: 1884ElizabethtonState: TNZip: 37643Country: USA

Doe River Bridge is a fine example of a timber Howe truss, one of the most widely-used timber bridge designs. Built in 1884, this structure played an integral role in the development of the City of Elizabethton, Tennessee, and it is a rare example of a covered bridge that survives in an urban setting.

The original contract specified the unusual hip roof design, which resembles covered bridges in central Europe. The structure is very well-maintained and still carries automobile traffic. The bridge was restored in 2003.

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.

This propulsion wind tunnel (PWT) at Arnold AFB was the first large-scale facility for testing jet and rocket engines in simulated high-speed flight conditions. It has a unique combination of transonic (1955) and supersonic (1960) wind tunnels using a common 236,000 horsepower drive, the world's largest when built. It can achieve air speeds up to Mach 4.75 at altitudes up to 150,000 feet in its 16-foot square, removable test sections. Design engineers were Lief J. Sverdrup, John R. Parcel, Brice Smith, and Walter Cook, of Sverdrup and Parcel, St.

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.

J.
This fusion-welded drum, tested during 1930, was the first in a series tested at Combustion Engineering Inc. that led to the industrial acceptance of welding for the fabrication of boiler drums. Replacing riveting for steam power plants, electric arc fusion welding permitted increased efficiencies through higher working pressures and temperatures and fabrication of larger units of improved safety. Welding was then rapidly extended to fabrication using optimum alloys for pressure vessel and structural application. Papers published by A. J.

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.
