Lumberville–Raven Rock Bridge
The Lumberville–Raven Rock Bridge, also known as the Lumberville Foot Bridge, is a free pedestrian bridge over the Delaware River. The bridge connects Bull's Island Recreation Area near Raven Rock, Delaware Township in Hunterdon County, New Jersey to Lumberville, Solebury Township in Bucks County, Pennsylvania, United States. The bridge, which is one of the two exclusively pedestrian bridges over the Delaware River, is owned and operated by the Delaware River Joint Toll Bridge Commission. History The Pennsylvania and New Jersey legislatures approved the construction of a bridge at Lumberville in 1835-1836, however construction was not begun until 1853. This delay spared the bridge the possible ravages of a major flood in 1841. The bridge, with four spans crossing the river and another crossing the Delaware Canal, was a wooden covered type, engineered by Solon Chapin of Easton, Pennsylvania, and a partner, Anthony Fry. The bridge was built by the Lumberville Delawar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedestrian
A pedestrian is a person traveling on foot, by wheelchair or with other mobility aids. Streets and roads often have a designated footpath for pedestrian traffic, called the '' sidewalk'' in North American English, the ''pavement'' in British English, and the ''footpath'' in Australian and New Zealand English. There are also footpaths not associated with thoroughfares; these include rural paths and urban short cuts. Historically, walking has been the main way people get around. In the early use of the word, ''pedestrian'' meant a "professional walker", or somebody who held a record for speed or endurance. With the advent of cars, it started to be used as an opposite: somebody who is not riding or driving. As walking is a healthy and sustainable mode of transport, there are efforts to make cities more walkable. For instance, by creating wider sidewalks, a pedestrian network, or restricting motor vehicles in city centres. Pedestrians are vulnerable and can be injured, for e ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Jersey Route 29
Route 29 is a state highway in the U.S. state of New Jersey. Signed north-south, it runs from an interchange with Interstate 295 (I-295) in Hamilton Township in Mercer County, where the road continues east as I-195, northwest to Route 12 (Bridge Street / Race Street) in Frenchtown, Hunterdon County. Between the southern terminus and I-295 in Ewing Township, the route is a mix of expressway and boulevard that runs along the Delaware River through Trenton. This section includes a truck-restricted tunnel that was built along the river near historic houses and Riverview Cemetery. North of I-295, Route 29 turns into a scenic and mostly two-lane highway. North of the South Trenton Tunnel, it is designated the Delaware River Scenic Byway, a New Jersey Scenic Byway and National Scenic Byway, that follows the Delaware River in mostly rural sections of Mercer County and Hunterdon County. The obsolete Delaware & Raritan Canal usually stands between the river and the highway. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end that provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus An abacus ( abaci or abacuses), also called a counting frame, is a hand-operated calculating tool which was used from ancient times in the ancient Near East, Europe, China, and Russia, until the adoptio ...

Pier (architecture)
A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers. External or free-standing walls may have piers at the ends or on corners. Description The simplest cross section (geometry), cross section of the pier is square (geometry), square, or rectangle, rectangular, but other shapes are also common. In medieval architecture, massive circle, circular supports called drum piers, cruciform (cross-shaped) piers, and compound piers are common architectural elements. Columns are a similar upright support, but stand on a round base; in many contexts columns may also be called piers. In buildings with a sequence of Bay (architecture), bays between piers, each opening (window or door) between two piers is considered a single bay. Bridge piers Single-span bridges have abutments at each end that support the weight of the bridge and serve as retaining walls to res ...

Pedestrian Bridge
A footbridge (also a pedestrian bridge, pedestrian overpass, or pedestrian overcrossing) is a bridge designed solely for pedestrians.''Oxford English Dictionary'' While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk, that enables pedestrians to cross wet, fragile, or marshy land. Bridges range from stepping stones–possibly the earliest man-made structure to "bridge" water–to elaborate steel structures. Another early bridge would have been simply a fallen tree. In some cases a footbridge can be both functional and artistic. For rural communities in the developing world, a footbridge may be a community's only access to medical clinics, schools, businesses and markets. Simple suspension bridge designs have been developed to be sustainable and easily constructed in such areas using only local materials and labor. An enclosed footbridge between two buildings is ...

John A Roebling
John Augustus Roebling (born Johann August Röbling; June 12, 1806 – July 22, 1869) was a German-born American civil engineer. He designed and built wire rope suspension bridges, in particular the Brooklyn Bridge, which has been designated as a National Historic Landmark and a National Historic Civil Engineering Landmark. Early life and education Röbling was born June 12, 1806, in Mühlhausen to Friederike Dorothea (née Muelleren) and Christoph Polykarpus Röbling. Recognizing his intelligence at a young age, Roebling's mother arranged for him to be tutored in mathematics and science at Erfurt by Ephraim Salomon Unger. He went to Erfurt when he was 15. In 1824 he passed his Surveyor's examination and returned home for a year. In 1824 he enrolled for two semesters at the Bauakademie in Berlin, where he studied architecture and engineering under Martin Friedrich Rabe (1765–1856), bridge construction and foundation construction under Johann Friedrich Dietlein (1782–1837), ...

Timber
Lumber is wood that has been processed into uniform and useful sizes (dimensional lumber), including beams and planks or boards. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber has many uses beyond home building. Lumber is referred to as timber in the United Kingdom, Australia, and New Zealand, while in other parts of the world, including the United States and Canada, the term ''timber'' refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut. Lumber may be supplied either rough- sawn, or surfaced on one or more of its faces. ''Rough lumber'' is the raw material for furniture-making, and manufacture of other items requiring cutting and shaping. It is available in many species, including hardwoods and softwoods, such as white pine and red pine, because of their low cost. ''Finished lumber'' is supplied in standard sizes, mostly for the construction ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
