Bridge In New Garden Township
The Landenberg Bridge is a truss bridge carrying Landenberg Road across the White Clay Creek in Landenberg, Pennsylvania. The bridge was originally built by the Schuylkill Bridge Company of Phoenixville, Pennsylvania in 1899, using the stone abutments from an earlier (1871) bridge. The 1899 bridge was a Pratt pony truss design, with an unusual cantilevered sidewalk along the north side of the bridge. Because of its architectural features, the Landenberg Bridge was placed on the National Register of Historic Places in 1988. However, a PennDOT The Pennsylvania Department of Transportation (PennDOT) oversees transportation issues in the Commonwealth of Pennsylvania.

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 ...

White Clay Creek
White Clay Creek is an U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed April 1, 2011 tributary of the Christina River in southern Pennsylvania and northern Delaware in the United States. It is renowned for its scenic character and is largely federally protected. The White Clay Creek watershed is home to nearly 100,000 people and includes parts of Chester County, Pennsylvania and New Castle County, Delaware. The Pennsylvania portion still retains a rural character while the Delaware portion is more suburbanized. Sediment eroded from the rolling hills of Chester County is carried into the White Clay, probably accounting for the creek's name. The majority of the stream is in the Piedmont region which is characterized by rolling hills, plateaus, and stream valleys. The southern portion of the stream, near Newark is in the Atlantic Coastal Plain, a relatively flat area that is dotted with large tidal wetlands. The White Cla ...

Phoenixville, Pennsylvania
Phoenixville is a Borough (Pennsylvania), borough in Chester County, Pennsylvania, United States. It is located northwest of Philadelphia, Pennsylvania, Philadelphia at the junction of French Creek (Schuylkill River tributary), French Creek and the Schuylkill River. It is in the Delaware Valley, Philadelphia metropolitan area. The population is 18,616 as of the 2020 Census.

Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southe ...

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] |

Bridges Completed In 1899
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] |
Truss Bridges In The United States
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as ''nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for t ...
