Atherton Bridge
The Atherton Bridge is a historic iron truss bridge in Lancaster, Massachusetts, spanning the South Branch of the Nashua River. It is a rare example of a hybrid pony truss that is similar to the 19th century truss design of Simeon S. Post. It was built by J. H. Cofrode & Co. of Philadelphia in 1870. It was the first iron bridge to be constructed in the town. The bridge was added to the National Register of Historic Places in 1979. The bridge formerly carried Bolton Road, but was closed to vehicular traffic in 1975 and bypassed by a modern highway bridge in the 1980s. The bridge remained open to pedestrian traffic until April 2020, when a flash flood damaged the bridge's wooden deck and it was closed to all traffic. The long-term future of the bridge is uncertain. The sign commemorating Atherton Bridge states: Technical information The Atherton Bridge has iron compression posts that incline inward towards the center of the span and diagonal tension rods that incline outward t ...

Lancaster, Massachusetts
Lancaster is a town in Worcester County, Massachusetts, in the United States. Incorporated in 1653, Lancaster is the oldest town in Worcester County. As of the 2020 census, the town population was 8,441. History In 1643 Lancaster was first settled as "Nashaway" (named after the local Nashaway Native American tribe) by a group of colonists known as the Nashaway Company who may have initially been interested in iron deposits in the area. Several of the company were blacksmiths or gunsmiths, including, Herman Garrett, and as early as 1653 a settler, George Adams, was whipped for selling guns and alcohol to the Indians in the area. The town was officially incorporated and renamed "Lancaster on the Nashua" in 1653. Prominent Massachusetts military leader Simon Willard served as an advisor to the company and eventually settled in Lancaster for a period, and provided guns to the local tribe by order of the Massachusetts General Court. Supporters of Lancaster's founder, John Pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Historic American Engineering Record In Massachusetts
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 Lancaster, Massachusetts
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, monument, 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 habitats, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Road Bridges In The United States
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Pedestrian Bridges In Massachusetts
A pedestrian is a person traveling on foot, whether walking or running. In modern times, the term usually refers to someone walking on a road or pavement, but this was not the case historically. The meaning of pedestrian is displayed with the morphemes ''ped-'' ('foot') and ''-ian'' ('characteristic of'). This word is derived from the Latin term ''pedester'' ('going on foot') and was first used (in English language) during the 18th century. It was originally used, and can still be used today, as an adjective meaning plain or dull. However, in this article it takes on its noun form and refers to someone who walks. The word pedestrian may have been used in middle French in the Recueil des Croniques et Anchiennes Istories de la Grant Bretaigne, à présent nommé Engleterre. In California the definition of a pedestrian has been broadened to include anyone on any human powered vehicle that is not a bicycle, as well as people operating self-propelled wheelchairs by reason of ph ...

Bridges In Worcester County, Massachusetts
A bridge is a structure built to Span (engineering), 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 ...

Road Bridges On The National Register Of Historic Places In Massachusetts
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 in ...

Ponakin Bridge
The Ponakin Bridge is a historic Post truss bridge spanning the Nashua River in northern Lancaster, Massachusetts. The bridge was built in 1871, and originally carried the main north–south road (now Ponakin Road), which was bypassed by the construction of Massachusetts Route 70. It is now unsafe and closed even to pedestrians. The bridge, with a design once common but now extremely rare, was listed on the National Register of Historic Places in 1979. Description and history The Ponakin Bridge is located in a rural setting several miles north of the village center of Lancaster, spanning the Nashua River in a roughly east–west orientation between Massachusetts Route 70 and Ponakin Road, a dead-end residential street paralleling the river's west bank. The bridge trusses consist of eight paneled sections with a total span of and a width of . It rests on granite stone abutments formed out of rough-cut stone long. The decking consists of a base of cross timbers which are attached t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...
