J. E. Greiner Company
J. E. Greiner Company was a Baltimore, Maryland-based civil engineering firm specializing in bridge design. History The firm was founded in 1908 by former Baltimore and Ohio Railroad bridge engineer John Edwin Greiner (February 24, 1859 – November 15, 1942) and led by Greiner and his associate Hershel Heathcote Allen.

Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in t ...

Governor Harry W
A governor is an administrative leader and head of a polity or political region, ranking under the head of state and in some cases, such as governors-general, as the head of state's official representative. Depending on the type of political region or polity, a ''governor'' may be either appointed or elected, and the governor's powers can vary significantly, depending on the public laws in place locally. The adjective pertaining to a governor is gubernatorial, from the Latin root ''gubernare''. Ancient empires Pre-Roman empires Though the legal and administrative framework of provinces, each administrated by a governor, was created by the Romans, the term ''governor'' has been a convenient term for historians to describe similar systems in antiquity. Indeed, many regions of the pre-Roman antiquity were ultimately replaced by Roman 'standardized' provincial governments after their conquest by Rome. Plato used the metaphor of turning the Ship of State with a rudder; the Latin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Silver Bridge
The Silver Bridge was an eyebar-chain suspension bridge built in 1928 and named for the color of its aluminum paint. The bridge carried U.S. Route 35 over the Ohio River, connecting Point Pleasant, West Virginia, and Gallipolis, Ohio. On December 15, 1967, the Silver Bridge collapsed under the weight of rush-hour traffic, resulting in the deaths of 46 people. Two of the victims were never found. Investigation of the wreckage pointed to the cause of the collapse being the failure of a single eyebar in a suspension chain, due to a small defect deep. Analysis showed that the bridge was carrying much heavier loads than it had been designed for and had been poorly maintained. The collapsed bridge was replaced by the Silver Memorial Bridge, which was completed in 1969. History of eyebar-chain bridge construction At the time of the Silver Bridge construction, eyebar bridges had been built for about 100 years. Such bridges had usually been constructed from redundant bar links, using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interstate 70 In Maryland
Interstate 70 (I-70) is a part of the Interstate Highway System that runs from Cove Fort, Utah, to Baltimore, Maryland. In Maryland, the Interstate Highway runs from the Pennsylvania state line in Hancock east to the Interstate's eastern terminus near its junction with I-695 at a park and ride in Baltimore. I-70 is the primary east–west Interstate in Maryland; the Interstate Highway connects Baltimore—and Washington, DC, via I-270—with Western Maryland. The Interstate serves Frederick and Hagerstown directly and provides access to Cumberland via its junction with I-68 at Hancock. I-70 runs concurrently with its predecessor highway, U.S. Route 40 (US 40), from Hancock to Indian Springs in Washington County and from Frederick to West Friendship in Howard County. I-70's route from Frederick to West Friendship was constructed as a divided highway relocation of US 40 in the early to mid-1950s and a freeway bypass of Frederick in the late 1950s. Th ...
