The crawler-transporters, formally known as the Missile Crawler Transporter Facilities, are a pair of tracked vehicles used to transport spacecraft from NASA's Vehicle Assembly Building (VAB) along the Crawlerway to Launch Complex 39. They were originally used to transport the Saturn IB and Saturn V rockets during the Apollo, Skylab and Apollo-Soyuz programs. They were then used to transport Space Shuttles from 1981 to 2011. The crawler-transporters carry vehicles on the mobile platform launchers used by NASA, and after each launch return to the pad to take the platform back to the VAB.

The Magma Copper Mine AC system designed by the Carrier Corporation was the first underground mechanical air conditioning system in North America. The initial installation of refrigerated cooling equipment in the Magma Mine at Superior, Arizona was necessary due to the increase in temperature lower into the mine. Below the 2000-foot level, the increase in rock temperature is approximately 1½ degrees F. per 100 feet of depth. The rock temperature on the 2000-foot level is 109°.

The Old Lock Pump House, whose first element was built in 1837, preserves a feature of the old canal, which relied on locks and pumps to move vessels over the low divide of the Delmarva Peninsula between Chesapeake Bay and Delaware Bay. Because there are no large rivers on the peninsula, water had to be pumped uphill to fill the upper canal and locks.

The Edger station was the first steam electric plant produced that could tolerate over 1000 psi of pressure. Initially conceived by Mr. Irving Edwin Moultrop, then Assistant Superintendent, Construction Bureau of the Edison Electric Illuminating Company of Boston. He guided his company and the electric utility industry on a major step forward into the higher-pressure range of 1,200 psi steam.

Duck Creek Aqueduct is a rare surviving example of a covered timber aqueduct. It was one of several similar structures on the Whitewater Canal, which operated between the Whitewater Valley and the Ohio River from 1839 to 1865. After being displaced by the railroad, the canal supplied hydraulic power for the industrial districts at Metamora and Brookville.

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.

Bunker Hill Covered Bridge
Main Category: CivilSub Category: BridgesEra: 1890-1899DateCreated: 18954160 US-70State: NCZip: 28610Country: USAWebsite: Andrew L. Ramsour

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.
