Wilson's Bridge
Wilson's Bridge is a bridge near Hagerstown, Washington County, Maryland, United States. It originally carried the Hagerstown and Conococheague Turnpike, the National Road, across Conococheague Creek west of Hagerstown. The five-arched structure, the longest of the county's stone bridges, is in length and is constructed of coursed local limestone. The bridge was erected in 1819 by Silas Harry, who had built similar bridges in Pennsylvania. The bridge was closed in June 1972 when it was damaged by floods which occurred during Tropical Storm Agnes. Wilson's Bridge was listed on the National Register of Historic Places in 1982.

Hagerstown, Maryland
Hagerstown is a city in Washington County, Maryland, United States and the county seat of Washington County. The population of Hagerstown city proper at the 2020 census was 43,527, and the population of the Hagerstown metropolitan area (extending into West Virginia) was 269,140. Hagerstown ranks as Maryland's sixth-largest incorporated city and is the largest city in the Panhandle. Hagerstown has a distinct topography, formed by stone ridges running from northeast to southwest through the center of town. Geography accordingly bounds its neighborhoods. These ridges consist of upper Stonehenge limestone. Many of the older buildings were built from this stone, which is easily quarried and dressed onsite. It whitens in weathering and the edgewise conglomerate and wavy laminae become distinctly visible, giving a handsome and uniquely "Cumberland Valley" appearance. Several of Hagerstown's churches are constructed of Stonehenge limestone. Its value and beauty as building rock may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Historic American Buildings Survey In Maryland
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Buildings And Structures In Hagerstown, Maryland
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Bridges On The National Register Of Historic Places In Maryland
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which i ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridge
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The '' Oxford English Dictionary'' traces the origin of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Agnes
Hurricane Agnes in 1972 was the costliest hurricane to hit the United States at the time, causing an estimated $2.1 billion in damage. The hurricane's death toll was 128. The effects of Agnes were widespread, from the Caribbean to Canada, with much of the east coast of the United States affected. Damage was heaviest in Pennsylvania, where Agnes was the state's wettest tropical cyclone. Due to the significant effects, the name ''Agnes'' was retired in the spring of 1973. Agnes was the second tropical cyclone and first named storm of the 1972 Atlantic hurricane season. It developed as a tropical depression on June 14 from the interaction of a polar front and an upper trough over the Yucatán Peninsula. The storm emerged into the western Caribbean Sea on June 15, and strengthened into Tropical Storm Agnes the next day. Thereafter, Agnes slowly curved northward and passed just west of Cuba on June 17. Early on June 18, the storm intensified enough to be u ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
