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 Delaware ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedestrian
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 p ...

Covered Bridge
A covered bridge is a timber-truss bridge with a roof, decking, and siding, which in most covered bridges create an almost complete enclosure. The purpose of the covering is to protect the wooden structural members from the weather. Uncovered wooden bridges typically have a lifespan of only 20 years because of the effects of rain and sun, but a covered bridge could last over 100 years. In the United States, only about 1 in 10 survived the 20th century. The relatively small number of surviving bridges is due to deliberate replacement, neglect, and the high cost of restoration. European and North American truss bridges Typically, covered bridges are structures with longitudinal timber-trusses which form the bridge's backbone. Some were built as railway bridges, using very heavy timbers and doubled up lattice work. In Canada and the U.S., numerous timber covered bridges were built in the late 1700s to the late 1800s, reminiscent of earlier designs in Germany and Switzerland. Th ...

Delaware And Raritan Canal State Park
Delaware and Raritan Canal State Park is a New Jersey state park along the Delaware and Raritan Canal. History In 1974, most of the canal system was declared a New Jersey state park. It remains one today, and is used for canoeing, kayaking, and fishing. A graded natural-surface trail along the side of the canal, which was the tow path that mules used to tow barges on the canal before steam powered barges, is now used for hiking, jogging, bicycling, and horseback riding. These trail connect with the trails in Pennsylvania's Delaware Canal State Park by way of five bridges that cross the Delaware River. Some of the main canal, and all of the feeder canal, still exist. The park is operated and maintained by the New Jersey Division of Parks and Forestry. The canal is accessible from many points along its route, with small parking areas providing access at most road crossings. One of the most scenic and popular sections of the D&R Canal state park is the segment along Lake Carneg ... [...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 which 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 of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...

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 of the pier is square, or rectangular, but other shapes are also common. In medieval architecture, massive 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 buildings with a sequence of 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 resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support the ends of spans betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Education John Röbling was born to Friederike Dorothea Röbling (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), hydraulics under Johann Albert ...

Timber
Lumber is wood that has been processed into dimensional lumber, including beams and planks or boards, a stage in the process of wood production. 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 sometimes referred to as timber as an archaic term and still in England, while in most parts of the world (especially 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. Beside pulpwood, ''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 ...

Hunterdon County Democrat
The ''Hunterdon County Democrat'' is a weekly newspaper that serves Hunterdon County, New Jersey. Currently owned by Penn Jersey Advance, Inc., its offices are in Raritan Township. It is one of the largest paid weekly newspapers in New Jersey, with an estimated total circulation of more than 21,000. It is published every Thursday. History The first newspaper to serve Hunterdon County was the ''Hunterdon Gazette and Farmers' Weekly Advertiser'', established at Flemington on March 24, 1825, by Charles George, who shortened the paper's title to the ''Hunterdon Gazette'' in 1829. He discontinued the ''Gazette'' on May 2, 1832, but retained his shop in Flemington and periodically published issues of the paper. George sold the ''Gazette'' to John S. Brown, who returned the paper to weekly publication beginning with his first issue, published on July 18, 1838. On the ''Gazette's'' editorial page, Brown state that he was "'an old-fashioned Democrat,' which was in reality an admissi ...
