Charles C. Glover Memorial Bridge
The Charles C. Glover Memorial Bridge or Massachusetts Avenue Bridge in Northwest Washington, D.C. conveys Massachusetts Avenue over Rock Creek and Rock Creek Park. The concrete arch bridge was constructed in 1939–41 and has a length of . History and name A much smaller iron truss bridge was built at the bottom of the valley in 1888, following the decision to extend Massachusetts Avenue beyond Florida Avenue. In 1901, this bridge was replaced with a land fill, with Rock Creek channeled through a large culvert. This in turn became inconvenient when Rock Creek Parkway was built in the 1930s. The construction of the bridge also allowed the level of Massachusetts Avenue to be raised significantly compared with the earlier bridge and land fill. The bridge was named after Charles Carroll Glover, who had played a decisive role in shaping this area of Northwest Washington and who died in 1936. On November 20, 1946, Stephen Norman, grandson of Theodor Herzl, jumped off the bridge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Concrete Bridges In The United States
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Road Bridges In Washington, D
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", w ...

Historic American Engineering Record In Washington, D
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 ...

Bridges Over Rock Creek (Potomac River Tributary)
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 the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Crossings Of Rock Creek
This is a list of crossings of Rock Creek. Rock Creek runs for 31 miles from its source in Montgomery County, Maryland, to its mouth at the Potomac River, of which the final nine miles lies in Washington, D.C. The entirety of Rock Creek downstream of the Maryland border is within Rock Creek Park (except for a small portion that runs through the National Zoo). The crossings built after Rock Creek Park was established in 1890 until World War II tended to be stone-faced bridges constructed to harmonize with the rustic surroundings, while postwar bridges were more utilitarian concrete and steel structures. Of the 35 crossings, 23 are covered by a Historic American Engineering Record (HAER), and two bridges—the gargantuan Taft Bridge and the bucolic Boulder Bridge—are on the National Register of Historic Places. By the early twentieth century, when the initial plans for the Rock Creek and Potomac Parkway were being made, many of the bridges along its intended path ...
