113-517: WR Draw is an out-of-service railroad bridge crossing the Passaic River between Newark and the Arlington section of Kearny , New Jersey . The plate girder rim-bearing swing bridge , originally built in 1897 and modified in 1911 and 1950, is the 14th bridge from the river's mouth at Newark Bay and is 8.1 miles (13.0 km) upstream from it. Last used for regular passenger service in 2002, it

226-656: A Radisson hotel ) in Scranton the following year. A new terminal was constructed on the waterfront in Buffalo in 1917. The "Lackawanna Railroad of New Jersey", chartered on February 7, 1908, to build the Lackawanna Cut-Off (a.k.a. New Jersey Cutoff or Hopatcong-Slateford Cutoff), opened on December 24, 1911. This provided a low-grade cutoff in northwestern New Jersey. The cutoff included the Delaware River Viaduct and

339-596: A bridge-restaurant which is a bridge built to serve as a restaurant. Other suspension bridge towers carry transmission antennas. Conservationists use wildlife overpasses to reduce habitat fragmentation and animal-vehicle collisions. The first animal bridges sprung up in France in the 1950s, and these types of bridges are now used worldwide to protect both large and small wildlife. Bridges are subject to unplanned uses as well. The areas underneath some bridges have become makeshift shelters and homes to homeless people, and

452-520: A bridge is to be designed, standards authorities specify simplified notional load models, notably HL-93, intended to give the same load effects as the characteristic maximum values. The Eurocode is an example of a standard for bridge traffic loading that was developed in this way. Most bridge standards are only applicable for short and medium spans - for example, the Eurocode is only applicable for loaded lengths up to 200 m. Longer spans are dealt with on

565-471: A case-by-case basis. It is generally accepted that the intensity of load reduces as span increases because the probability of many trucks being closely spaced and extremely heavy reduces as the number of trucks involved increases. It is also generally assumed that short spans are governed by a small number of trucks traveling at high speed, with an allowance for dynamics. Longer spans on the other hand, are governed by congested traffic and no allowance for dynamics

678-480: A combination of structural health monitoring and testing. This is regulated in country-specific engineer standards and includes an ongoing monitoring every three to six months, a simple test or inspection every two to three years and a major inspection every six to ten years. In Europe, the cost of maintenance is considerable and is higher in some countries than spending on new bridges. The lifetime of welded steel bridges can be significantly extended by aftertreatment of

791-554: A cost of $ 2 million, including a massive machine and erecting shop measuring 582 by 342 feet. To handle the increasing roster of coal and other freight cars, new car shops were built outside Scranton at Keyser Valley in 1904. A passenger car shop was added in Kingsland, New Jersey, nine miles from New York City, in 1906. The company built a Beaux-Arts terminal in Hoboken, New Jersey , in 1907, and another Beaux-Arts passenger station (now

904-399: A different site, and re-used. They are important in military engineering and are also used to carry traffic while an old bridge is being rebuilt. Movable bridges are designed to move out of the way of boats or other kinds of traffic, which would otherwise be too tall to fit. These are generally electrically powered. The Tank bridge transporter (TBT) has the same cross-country performance as

1017-491: A division of the Livonia , Avon , and Lakeville Railroad). Shorter main line remnants are Groveland -Greigsville (Genesee & Wyoming) and Lancaster - Depew (Depew, Lancaster & Western). The Richfield Springs branch was scrapped in 1998 after being out of service for years; much of the right of way was purchased in 2009 by Utica, Chenango and Susquehanna Valley LLC of Richfield Springs, New York, which as of 2022 operates

1130-594: A few will predominate. The separation of forces and moments may be quite clear. In a suspension or cable-stayed bridge , the elements in tension are distinct in shape and placement. In other cases the forces may be distributed among a large number of members, as in a truss. The world's longest beam bridge is Lake Pontchartrain Causeway in southern Louisiana in the United States, at 23.83 miles (38.35 km), with individual spans of 56 feet (17 m). Beam bridges are

1243-475: A large passenger traffic for the Lackawanna. All of this helped justify the railroad's expansion of its double-track mainline to three and in a few places four tracks. Changes in the region's economy undercut the railroad, however. The post- World War II boom enjoyed by many U.S. cities bypassed Scranton, Wilkes-Barre and the rest of Lackawanna and Luzerne counties. Fuel oil and natural gas quickly became

1356-655: A merger agreement with the Erie Railroad , the DL&;W's longtime rival (and closest geographical competitor), forming the Erie Lackawanna Railroad . The merger was formally consummated on October 17, 1960. Shoemaker drew much criticism for it, and would even second-guess himself after he had retired from railroading. He later claimed to have had a "gentlemen's agreement" with the EL board of directors to take over as president of

1469-762: A modernized ROW from its Pavonia Terminal for use by both the NYGL and the Newark Branch , which crossed the Passaic on the NX Bridge at the southern end of Kearny. Within Erie, the NX was known as Bridge 8.04, which indicated the number of miles from the Jersey City waterfront terminal. The WR Draw was known as Bridge 7.57. In the mid-1890s, the Erie greatly expanded the infrastructure and service on

1582-624: A narrow-gauge tourist railway Richfield Springs Scenic Railway on a portion of the line and a walking trail on another section. The Cortland- Cincinnatus Branch, abandoned by Erie Lackawanna in 1960, was partially-rebuilt for an industrial spur about 1999. As of 2018, the Reading Blue Mountain and Northern operates the former Keyser Valley branch from Scranton to Taylor, as well as the former Bloomsburg branch from Taylor to Coxton Yard in Duryea . The Luzerne and Susquehanna Railway operates

1695-558: A short segment of the Boonton Branch by Garret Mountain in Paterson, New Jersey , was sold off to the state of New Jersey to build Interstate 80 . Ultimately, the west end of the Boonton Branch was combined with the Erie's Greenwood Lake Branch, while the eastern end was combined with the Erie's main line, which was abandoned through Passaic, New Jersey . Sacrificed was the Boonton Branch, a high-speed freight line thought to be redundant with

1808-553: A simple type of suspension bridge , were used by the Inca civilization in the Andes mountains of South America, just prior to European colonization in the 16th century. The Ashanti built bridges over streams and rivers . They were constructed by pounding four large forked tree trunks into the stream bed, placing beams along these forked pillars, then positioning cross-beams that were finally covered with four to six inches of dirt. During

1921-578: A span of 552 m (1,811 ft). The bridge was opened 29 April 2009, in Chongqing , China. The longest suspension bridge in the world is the 4,608 m (15,118 ft) 1915 Çanakkale Bridge in Turkey. The longest cable-stayed bridge since 2012 is the 1,104 m (3,622 ft) Russky Bridge in Vladivostok , Russia. Some Engineers sub-divide 'beam' bridges into slab, beam-and-slab and box girder on

2034-732: A stream. Often in palaces, a bridge will be built over an artificial waterway as symbolic of a passage to an important place or state of mind. A set of five bridges cross a sinuous waterway in an important courtyard of the Forbidden City in Beijing, China. The central bridge was reserved exclusively for the use of the Emperor and Empress, with their attendants. The estimated life of bridges varies between 25 and 80 years depending on location and material. Bridges may age hundred years with proper maintenance and rehabilitation. Bridge maintenance consisting of

2147-479: A tank even when fully loaded. It can deploy, drop off and load bridges independently, but it cannot recover them. Double-decked (or double-decker) bridges have two levels, such as the George Washington Bridge , connecting New York City to Bergen County , New Jersey , US, as the world's busiest bridge, carrying 102 million vehicles annually; truss work between the roadway levels provided stiffness to

2260-505: A tremendous financial drain on the Lackawanna and other railroads that ran through the state: a situation that would not be remedied for another two decades. To save his company, Lackawanna president Perry Shoemaker sought a merger with the Nickel Plate Road , a deal that would have created a railroad stretching more than 1,100 miles (1,800 km) from St. Louis, Missouri and Chicago, Illinois to New York City and would have allowed

2373-456: Is a bridge that carries water, resembling a viaduct, which is a bridge that connects points of equal height. A road-rail bridge carries both road and rail traffic. Overway is a term for a bridge that separates incompatible intersecting traffic, especially road and rail. Some bridges accommodate other purposes, such as the tower of Nový Most Bridge in Bratislava , which features a restaurant, or

2486-574: Is an early example of a double-decked bridge. The upper level carries a railway, and the lower level is used for road traffic. Other examples include Britannia Bridge over the Menai Strait and Craigavon Bridge in Derry, Northern Ireland. The Oresund Bridge between Copenhagen and Malmö consists of a four-lane highway on the upper level and a pair of railway tracks at the lower level. Tower Bridge in London

2599-485: Is different example of a double-decked bridge, with the central section consisting of a low-level bascule span and a high-level footbridge . A viaduct is made up of multiple bridges connected into one longer structure. The longest and some of the highest bridges are viaducts, such as the Lake Pontchartrain Causeway and Millau Viaduct . A multi-way bridge has three or more separate spans which meet near

2712-417: Is led by architects, bridges are usually designed by engineers. This follows from the importance of the engineering requirements; namely spanning the obstacle and having the durability to survive, with minimal maintenance, in an aggressive outdoor environment. Bridges are first analysed; the bending moment and shear force distributions are calculated due to the applied loads. For this, the finite element method

2825-540: Is needed. Calculating the loading due to congested traffic remains a challenge as there is a paucity of data on inter-vehicle gaps, both within-lane and inter-lane, in congested conditions. Weigh-in-Motion (WIM) systems provide data on inter-vehicle gaps but only operate well in free flowing traffic conditions. Some authors have used cameras to measure gaps and vehicle lengths in jammed situations and have inferred weights from lengths using WIM data. Others have used microsimulation to generate typical clusters of vehicles on

2938-737: Is the most popular. The analysis can be one-, two-, or three-dimensional. For the majority of bridges, a two-dimensional plate model (often with stiffening beams) is sufficient or an upstand finite element model. On completion of the analysis, the bridge is designed to resist the applied bending moments and shear forces, section sizes are selected with sufficient capacity to resist the stresses. Many bridges are made of prestressed concrete which has good durability properties, either by pre-tensioning of beams prior to installation or post-tensioning on site. In most countries, bridges, like other structures, are designed according to Load and Resistance Factor Design (LRFD) principles. In simple terms, this means that

3051-573: Is welded in closed position as its height is not considered a hazard to navigation. The lower seventeen miles (27 km) of the ninety-mile (140 km) long Passaic River downstream of the Dundee Dam is tidally influenced and navigable . Rail service across the river was generally oriented to bringing passengers and freight from the points west over the Hackensack Meadows to Bergen Hill , where tunnels and cuts provided access terminals on

3164-687: The Central Railroad of New Jersey abandoned all its operations in Pennsylvania (which by that time were freight-only), causing additional through freights to be run daily between Elizabeth, NJ on the CNJ and Scranton on the EL. The trains, designated as the eastbound SE-98 and the westbound ES-99, travelled via the Lackawanna Cut-Off and were routed via the CNJ 's High Bridge Branch . This arrangement ended with

3277-618: The Hellenistic era can be found in the Peloponnese. The greatest bridge builders of antiquity were the ancient Romans . The Romans built arch bridges and aqueducts that could stand in conditions that would damage or destroy earlier designs, some of which still stand today. An example is the Alcántara Bridge , built over the river Tagus , in Spain. The Romans also used cement, which reduced

3390-564: The Hudson Palisades . The bridge was again modified in the 1950s when New Jersey Route 21 was constructed under its west end. In 1943, in a major re-organization, the New York and Greenwood Lake as well as other subsidiaries were absorbed into the Erie. In 1960 the Erie and the Delaware, Lackawanna, and Western (DL&W) merged, consolidating at Hoboken Terminal . In 1963, in conjunction with

3503-577: The Kearny Connection , opened in 1996. This facilitates part of NJ Transit's popular Midtown Direct service. Formerly, the line ran solely to the DL&W's historic terminal in Hoboken and a transfer to underground rapid transit was required to pass under the Hudson river into Manhattan, or a ferry. This is the only section of former Lackawanna trackage that has more through tracks now than ever before. Since

3616-782: The New York and Greenwood Lake Railway (NYGL), under control of Erie Railroad . In 1887, the Erie created a new subsidiary, the Arlington Railroad, to create a new ROW in the Kearny Meadows which ran more directly to the WR Draw once the line had passed through the Long Dock Tunnel and crossed the Hackensack River . In 1889, it opened the DB Draw over the river, providing the company

3729-546: The North Jersey suburbs to Hoboken on the Boonton , Gladstone , Montclair and Morristown Lines. Early publicity for the passenger service featured a young woman, Phoebe Snow , who always wore white and kept her clothing clean while riding the "Road of Anthracite", powered by the clean-burning coal known as anthracite . The most profitable commodity shipped by the railroad was anthracite coal . In 1890 and during 1920–1940,

3842-652: The Paulinskill Viaduct , as well as three concrete towers at Port Morris and Greendell in New Jersey and Slateford Junction in Pennsylvania. From 1912 to 1915, the Summit-Hallstead Cutoff (a.k.a. Pennsylvania Cutoff or Nicholson Cutoff ) was built to revamp a winding and hilly system between Clarks Summit, Pennsylvania , and Hallstead, Pennsylvania . This rerouting provided another quicker low-grade line between Scranton and Binghamton. The Summit Cutoff included

3955-833: The University of Minnesota ). Likewise, in Toronto , the Prince Edward Viaduct has five lanes of motor traffic, bicycle lanes, and sidewalks on its upper deck; and a pair of tracks for the Bloor–Danforth subway line on its lower deck. The western span of the San Francisco–Oakland Bay Bridge also has two levels. Robert Stephenson 's High Level Bridge across the River Tyne in Newcastle upon Tyne , completed in 1849,

4068-495: The river Severn . With the Industrial Revolution in the 19th century, truss systems of wrought iron were developed for larger bridges, but iron does not have the tensile strength to support large loads. With the advent of steel, which has a high tensile strength, much larger bridges were built, many using the ideas of Gustave Eiffel . In Canada and the United States, numerous timber covered bridges were built in

4181-581: The "Delaware, Lackawanna and Western Railroad", on March 11, 1853. On the New Jersey side of the Delaware River, the Warren Railroad was chartered on February 12, 1851, to continue from the bridge over the river southeast to Hampton , on the Central Railroad of New Jersey . That section got its name from Warren County , the county through which it would primarily run. The rest of the line, now known as

4294-521: The 13th century BC, in the Peloponnese is one of the oldest arch bridges in existence and use. The Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg , of the same meaning.   The Oxford English Dictionary also notes that there is some suggestion that the word can be traced directly back to Proto-Indo-European *bʰrēw-. However, they also note that "this poses semantic problems." The origin of

4407-511: The 18th century, there were many innovations in the design of timber bridges by Hans Ulrich Grubenmann , Johannes Grubenmann , as well as others. The first book on bridge engineering was written by Hubert Gautier in 1716. A major breakthrough in bridge technology came with the erection of the Iron Bridge in Shropshire, England in 1779. It used cast iron for the first time as arches to cross

4520-474: The 1959 Knox Mine Disaster and competition from trucks following the expansion of the Interstate Highway System in the 1960s and 1970s. In 1960, the DL&W merged with rival Erie Railroad to form the Erie Lackawanna Railroad that would be taken over by Conrail in 1976. Delaware, Lackawanna and Western Railroad was first incorporated as Leggett's Gap Railroad on April 7, 1832, though it

Other commercial customers include Keystone Propane in Tobyhanna. Excursion trains, hauled by visiting Nickel Plate 765 and other locomotives, run from Steamtown to Moscow and Tobyhanna (with infrequent extensions to East Stroudsburg or Delaware Water Gap Station, both on

4859-591: The DL&W main line portion between Scranton and Binghamton (which includes the Nicholson Cutoff ) bought by the Delaware and Hudson Railway . The D&H was purchased by the Canadian Pacific Railway in 1991. CPR continued to run this portion of the DL&W main line until 2014, when it sold it to the Norfolk Southern . The Syracuse and Utica branches north of Binghamton were sold by Conrail to

4972-472: The DL&W shipped upwards of 14% of the state of Pennsylvania's anthracite production. Other profitable freight included dairy products, cattle, lumber, cement, steel and grain. The Pocono Mountains region was one of the most popular vacation destinations in the country—especially among New Yorkers—and several large hotels sat along the line in Northeastern Pennsylvania , generating

5085-619: The DL&W, which owned a substantial block of Nickel Plate stock, to place one of its directors on the Nickel Plate board . (The Nickel Plate would later merge with the Norfolk and Western Railroad .) Shoemaker next turned, in 1956, to aggressive but unsuccessful efforts to obtain joint operating agreements and even potential mergers with the Lehigh Valley Railroad and the Delaware and Hudson Railway . Finally, Shoemaker sought and won

5198-503: The Delaware Otsego Corp., which operates them as the northern division of the New York, Susquehanna and Western Railway . In 1997, Conrail accepted an offer of purchase from CSX Transportation and Norfolk Southern Railway . On June 1, 1999, Norfolk Southern took over many of the Conrail lines in New Jersey, including most of the former DL&W. It also purchased the remnants of the former Bangor & Portland branch in Pennsylvania. Norfolk Southern continues to operate local freights on

5311-471: The EL's decline. By 1976, it was apparent that the EL was at the end of its tether, and it petitioned to join Conrail : a new regional railroad that was created on April 1, 1976, out of the remnants of seven bankrupt freight railroads in the northeastern U.S. The EL's rail property was legally conveyed into Conrail on April 1, 1976. Labor contracts limited immediate changes to the freight schedule, but in early 1979, Conrail suspended through freight service on

5424-466: The Erie's main line, was abandoned in favor of joint operations, while the Lackawanna Cut-Off in New Jersey was single-tracked in anticipation of the upcoming merger. On the other hand, the Erie's Buffalo, New York and Erie Railroad was dropped from Corning to Livonia in favor of the DL&W's main line. Most passenger service was routed onto the DL&W east of Binghamton, with the DL&W's Hoboken Terminal serving all EL passenger trains. In addition,

5537-477: The Erie's mainline. This would haunt EL management less than a decade later (and Conrail management a decade after that). Soon after the merger, the new EL management shifted most freight trains to the "Erie side", the former Erie Railroad lines, leaving only a couple of daily freight trains traveling over the Lackawanna side. Passenger train traffic would not be affected, at least not immediately. This traffic pattern would remain in effect for more than ten years—past

5650-415: The Greenwood Lake, taking over the Watchung Railway in 1895 and the Caldwell Railway and the Roseland Railway in 1897, the former becoming the Orange Branch and the latter two, the Caldwell Branch. The WR Draw was modified in 1911 when the Erie opened a new tunnel-cut, the Bergen Arches , in Jersey City, creating the Penhorn Creek Railroad to run through it and make connections to its lines on the west side of

5763-410: The Hudson River . An alignment crossing the river at Arlington and North Newark was part of a grander scheme developed in the 1860s by the New York, Oswego, and Midland Railroad to run lines from Jersey City into northern New Jersey and beyond to Western New York , also opening up new areas for suburban development (including Belleville , just north of the current bridge's western end). Originally,

5876-412: The Lackawanna side. Indeed, as very little on-line freight originated on the Erie side (a route that was more than 20 miles longer than the DL&W route to Binghamton), once the Gateway was closed (eliminating the original justification for shifting traffic to the Erie side) virtually all the EL's freight trains were shifted back to the Lackawanna side. After the New England Gateway closed, EL's management

5989-401: The Lackawanna side. The railroad removed freight traffic from the Hoboken-Binghamton mainline and consolidated the service within its other operating routes. Railroad officials said the primary reasons were the EL's early-1960s severing of the Boonton Branch near Paterson, New Jersey , and the grades over the Pocono Mountains. The Morristown Line is the only piece of multi-track railroad on

6102-494: The Lackawanna to retain the 200 miles (320 km) of double-track mainline between Buffalo and Binghamton, New York . The idea had been studied as early as 1920, when William Z. Ripley , a professor of political economics at Harvard University , reported that a merger would have benefited both railroads. Forty years later, however, the Lackawanna was a shadow of its former financial self. Seeing no advantage in an end-to-end merger, Nickel Plate officials also rebuffed attempts by

6215-424: The Lackawanna, however, were dealt by Mother Nature . In August, 1955, flooding from Hurricane Diane devastated the Pocono Mountains region, killing 80 people. The floods cut the Lackawanna Railroad in 88 places, destroying 60 miles (97 km) of track, stranding several trains (with a number of passengers aboard) and shutting down the railroad for nearly a month (with temporary speed restrictions prevailing on

6328-437: The M&E lease came several branch lines in New Jersey, including the Boonton Line , which opened in 1870 and bypassed Newark for through freight. The railroad acquired the Syracuse, Binghamton and New York Railroad in 1869 and leased the Oswego and Syracuse Railroad on February 13, 1869. This gave it a branch from Binghamton north and northwest via Syracuse to Oswego , a port on Lake Ontario . The "Greene Railroad"

6441-424: The Pennsylvania Northeast Regional Rail Authority to accelerate the resumption of passenger train service between New York City and Scranton. Most of the main line west of Binghamton in New York State has been abandoned, in favor of the Erie's Buffalo line via Hornell . The longest remaining main line sector is Painted Post -Wayland, with shortline service provided by B&H Railroad ( Bath & Hammondsport ,

6554-438: The Pocono Mainline). The D-L also runs Lackawanna County 's tourist trolleys from the Electric City Trolley Museum , under overhead electrified wiring installed on original sections of the Lackawanna and Wyoming Valley Railroad that was also purchased by Lackawanna County. It also runs trains on a remnant of the DL&W Diamond branch in Scranton. In 2006, the Monroe County and Lackawanna County Railroad Authorities formed

6667-401: The Southern Division, opened on May 27, 1856, including the Warren Railroad in New Jersey . A third rail was added to the standard gauge Central Railroad of New Jersey east of Hampton to allow the railroad to run east to Elizabeth via trackage rights (the CNJ was extended in 1864 to Jersey City ). On December 10, 1868, the company acquired the Morris and Essex Railroad unit 1945 it

6780-496: The appearance of the bridge can have great importance. Often, this is the case with a large bridge that serves as an entrance to a city, or crosses over a main harbor entrance. These are sometimes known as signature bridges. Designers of bridges in parks and along parkways often place more importance on aesthetics, as well. Examples include the stone-faced bridges along the Taconic State Parkway in New York. Bridges are typically more aesthetically pleasing if they are simple in shape,

6893-416: The attention of the general public in the 1990s by the novel, movie and play The Bridges of Madison County . In 1927, welding pioneer Stefan Bryła designed the first welded road bridge in the world, the Maurzyce Bridge which was later built across the river Słudwia at Maurzyce near Łowicz , Poland in 1929. In 1995, the American Welding Society presented the Historic Welded Structure Award for

A slab can be solid or voided (though this is no longer favored for inspectability reasons) while beam-and-slab consists of concrete or steel girders connected by a concrete slab. A box-girder cross-section consists of a single-cell or multi-cellular box. In recent years, integral bridge construction has also become popular. Most bridges are fixed bridges, meaning they have no moving parts and stay in one place until they fail or are demolished. Temporary bridges, such as Bailey bridges , are designed to be assembled, taken apart, transported to

7119-437: The bridge to Poland. Bridges can be categorized in several different ways. Common categories include the type of structural elements used, by what they carry, whether they are fixed or movable, and by the materials used. Bridges may be classified by how the actions of tension , compression , bending , torsion and shear are distributed through their structure. Most bridges will employ all of these to some degree, but only

7232-413: The bridge. Delaware, Lackawanna, and Western Like most coal-focused railroads in Northeastern Pennsylvania, including Lehigh Valley Railroad , New York, Ontario and Western Railroad , and the Lehigh & New England Railroad , the DL&W was profitable during the first half of the 20th century, but its margins were gradually hurt by declining Pennsylvania coal traffic, especially following

7345-423: The bridge. New Jersey Transit Rail Operations (NJT) took over Conrail's commuter lines in 1983. With the 2002 opening of the Montclair Connection , NJT re-routed the Boonton Line to its Montclair Branch east of Montclair, thus bypassing the ROW to the bridge. Service was discontinued to Rowe Street , Benson Street and Arlington stations. DB Draw over the Hackensack River was also taken out of use and left in

7458-439: The center of the bridge. Multi-way bridges with only three spans appear as a "T" or "Y" when viewed from above. Multi-way bridges are extremely rare. The Tridge , Margaret Bridge , and Zanesville Y-Bridge are examples. A bridge can be categorized by what it is designed to carry, such as trains, pedestrian or road traffic ( road bridge ), a pipeline ( Pipe bridge ) or waterway for water transport or barge traffic. An aqueduct

That same year, it also began to control the Bangor and Portland Railway . By 1909, the company controlled the Bangor and Portland Railway . This line branched from the main line at Portland , southwest to Nazareth , with a branch to Martins Creek . The primary locomotive and car shops were located in Scranton . In 1910 they were enlarged and upgraded at

Numerous stations were taken out of use and the mainline was retracted in 1935. By 1966 service on the New York and Greenwood Lake was terminated. In 1976, the Erie-Lackawanna was taken over by Conrail which continued to run Boonton Line trains over

A 7.3-mile section of the Cut-Off between Port Morris and Andover, New Jersey , which was under construction, was delayed until 2021 due to environmental issues on the Andover station site ; the Cut-Off between Port Morris and Andover is slated to re-open for rail passenger service no earlier than 2025. In 1979, Conrail sold most of the DL&W in Pennsylvania, with

During its time, the EL diversified its shipments from the growing Lehigh Valley and also procured a lucrative contract with Chrysler to ship auto components from Mount Pocono, Pennsylvania . The EL also aggressively sought other contracts with suppliers in the area, pioneering what came to be known as intermodal shipping. None of this could compensate for

One section, the Old River line (former Warren Railroad), was damaged beyond repair and had to be abandoned altogether. Until the mainline in Pennsylvania reopened, all trains were canceled or rerouted over other railroads. The Lackawanna would never fully recover. In January, 1959,

To create a beautiful image, some bridges are built much taller than necessary. This type, often found in east-Asian style gardens, is called a Moon bridge , evoking a rising full moon. Other garden bridges may cross only a dry bed of stream-washed pebbles, intended only to convey an impression of

8249-461: The decline in coal shipments, however, and, as labor costs and taxes rose, the railroad's financial position became increasingly precarious although it was stronger than some railroads in the eastern U.S. The opening of Interstates I-80 , I-380 , and I-81 during the early 1970s, which in effect paralleled much of the former Lackawanna mainline east of Binghamton, New York , caused more traffic to be diverted to trucks. This only helped to accelerate

8362-673: The discontinuation of passenger service on January 6, 1970—and was completely dependent on the lucrative interchange with the New Haven Railroad at Maybrook, New York . The January 1, 1969 merger of the New Haven Railroad into the Penn Central Railroad changed all this: the New England Gateway was downgraded, and closed on May 8, 1974 by fire damage to the New Haven's Poughkeepsie Bridge, causing dramatic traffic changes for

8475-451: The entire 900-mile Lackawanna system that has not been reduced to fewer tracks over the years. It was triple-tracked nearly a century prior , and remains so today. The Lackawanna Cut-Off was abandoned in 1979 and its rails were removed in 1984. The line between Slateford Junction and Scranton remained in legal limbo for nearly a decade, but was eventually purchased, with a single track left in place. The Lackawanna Cut-Off's right-of-way, on

8588-557: The final nail was driven in the Lackawanna's coffin by the Knox Mine Disaster , which flooded the mines along the Susquehanna River and all but obliterated what was left of the region's anthracite industry. The Lackawanna Railroad's financial problems were not unique. Rail traffic in the U.S. in general declined after World War II as trucks and automobiles took freight and passenger traffic. Declining freight traffic put

8701-595: The first human-made bridges with significant span were probably intentionally felled trees. Among the oldest timber bridges is the Holzbrücke Rapperswil-Hurden bridge that crossed upper Lake Zürich in Switzerland; prehistoric timber pilings discovered to the west of the Seedamm causeway date back to 1523 BC. The first wooden footbridge there led across Lake Zürich; it was reconstructed several times through

8814-677: The former Morris & Essex Railroad to Gladstone and Hackettstown. In 2002, the transit agency consolidated the Montclair Branch and Boonton Line to create the Montclair-Boonton Line . NJ Transit also operates on the remaining portion (south of Paterson) of the original Boonton Line known as the Main Line . NJ Transit's hub is at Hoboken Terminal. Trains on the Morristown Line run directly into New York's Pennsylvania Station via

8927-748: The late 1700s to the late 1800s, reminiscent of earlier designs in Germany and Switzerland. Some covered bridges were also built in Asia. In later years, some were partly made of stone or metal but the trusses were usually still made of wood; in the United States, there were three styles of trusses, the Queen Post, the Burr Arch and the Town Lattice. Hundreds of these structures still stand in North America. They were brought to

9040-464: The late 2nd century AD, when the Roman Empire built a 6-metre-wide (20 ft) wooden bridge to carry transport across the lake. Between 1358 and 1360, Rudolf IV, Duke of Austria , built a 'new' wooden bridge across the lake that was used until 1878; it was approximately 1,450 metres (4,760 ft) long and 4 metres (13 ft) wide. On 6 April 2001, a reconstruction of the original wooden footbridge

9153-532: The lines. In 2014, it purchased the former DL&W main from Taylor, PA to Binghamton, NY from the Canadian Pacific Railway, which it continues to operate to this day. NJ Transit Rail Operations took over passenger operations in 1983. The State of New Jersey had subsidized the routes operated by the Erie Lackawanna, and later Conrail . NJ Transit operates over former DL&W trackage on much of

9266-427: The load is factored up by a factor greater than unity, while the resistance or capacity of the structure is factored down, by a factor less than unity. The effect of the factored load (stress, bending moment) should be less than the factored resistance to that effect. Both of these factors allow for uncertainty and are greater when the uncertainty is greater. Most bridges are utilitarian in appearance, but in some cases,

9379-438: The massive Tunkhannock Viaduct and Martins Creek Viaduct . The Lackawanna's cutoffs had no at-grade crossings with roads or highways, allowing high-speed service. The railroad ran trains from its Hoboken Terminal , its gateway to New York City , to its Scranton , Binghamton, Syracuse , Oswego, and Buffalo stations and to Utica Union Station . Noteworthy among these were: The railroad also ran commuter operations from

9492-495: The nearby New York, Ontario and Western Railroad and Lehigh & New England Railroad out of business in 1957 and 1961, respectively. Over the next three decades, nearly every major railroad in the Northeastern US would go bankrupt . In the wake of Hurricane Diane in 1955, all signs pointed to continued financial decline and eventual bankruptcy for the DL&W. Among other factors, property taxes in New Jersey were

9605-465: The new railroad. After he was pushed aside in favor of Erie managers, however, he left in disillusionment and became the president of the Central Railroad of New Jersey in 1962. Even before the formal merger, growing ties between the Erie and Lackawanna led to the partial abandonment of the Lackawanna's mainline trackage between Binghamton and Buffalo. In 1958, the main line of the DL&W from Binghamton west to near Corning , which closely paralleled

9718-614: 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, 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

9831-494: The open position. In 2020, Norfolk Southern Railway (NS), which had acquired the line in 1999 from Conrail, officially abandoned an 8.63-mile (13.89 km) section (milepost WD 2.9 to milepost WD 11.5) of the rail line. and the Open Space Institute (OSI) reached a preliminary sale agreement with NS for the property. The New Jersey Department of Environmental Protection , which manages state parks and forests, acquired

9944-452: The other hand, was purchased by the state of New Jersey in 2001 from funds approved within a $ 40 million bond issue in 1989. (A court later set the final price at $ 21 million, paid to owners Jerry Turco of Kearny, New Jersey and Burton Goldmeier of Hopatcong, New Jersey.) NJ Transit has estimated that it would cost $ 551 million to restore service to Scranton over the Cut-Off: a price which includes

10057-629: The past, these load models were agreed by standard drafting committees of experts but today, this situation is changing. It is now possible to measure the components of bridge traffic load, to weigh trucks, using weigh-in-motion (WIM) technologies. With extensive WIM databases, it is possible to calculate the maximum expected load effect in the specified return period. This is an active area of research, addressing issues of opposing direction lanes, side-by-side (same direction) lanes, traffic growth, permit/non-permit vehicles and long-span bridges (see below). Rather than repeat this complex process every time

10170-535: The plan called for incorporating the Montclair Railway which had been established in 1867. Ultimately that plan was scuttled as a route was established farther north connecting to the New Jersey Midland Railway and Hudson Connecting Railway . Nonetheless, expansion on the Montclair Railway continued and a right-of-way (ROW) over the river was established circa 1872-1874, The WR Draw's predecessor

10283-465: The preferred energy sources. Silk and other textile industries shrank as jobs moved to the southern U.S. or overseas. The advent of mechanical refrigeration squeezed the business from ice ponds on top of the Poconos . Even the dairy industry changed. The Lackawanna had long enjoyed revenues from milk shipments; many stations had a creamery next to the tracks. Perhaps the most catastrophic blows to

10396-468: The principles of Load and Resistance Factor Design . Before factoring to allow for uncertainty, the load effect is generally considered to be the maximum characteristic value in a specified return period . Notably, in Europe, it is the maximum value expected in 1000 years. Bridge standards generally include a load model, deemed to represent the characteristic maximum load to be expected in the return period. In

10509-509: The property on August 19, 2022. The state purchased the ROW from NS for $ 65 million for development of a new state park called the Essex–Hudson Greenway . Railroad bridge A bridge is a structure built to span a physical obstacle (such as a body of water , valley , road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over

10622-499: The railroad obtained trackage rights north and west over the New York and Erie Rail Road to Owego, New York , where it leased the Cayuga and Susquehanna Railroad to Ithaca on Cayuga Lake on April 21, 1855. The C&S was the reorganized and partially rebuilt Ithaca and Owego Railroad , which had opened on April 1, 1834, and was the oldest part of its system. The whole system was built to 6 ft ( 1,829 mm ) broad gauge ,

10735-742: The roadways and reduced movement of the upper level when the lower level was installed three decades after the upper level. The Tsing Ma Bridge and Kap Shui Mun Bridge in Hong Kong have six lanes on their upper decks, and on their lower decks there are two lanes and a pair of tracks for MTR metro trains. Some double-decked bridges only use one level for street traffic; the Washington Avenue Bridge in Minneapolis reserves its lower level for automobile and light rail traffic and its upper level for pedestrian and bicycle traffic (predominantly students at

10848-648: The same as the New York and Erie, although the original I&O was built to standard gauge and converted to wide gauge when rebuilt as the C&;S. The "Delaware and Cobb's Gap Railroad" was chartered December 4, 1850, to build a line from Scranton east to the Delaware River . Before it opened, the Delaware and Cobb's Gap and Lackawanna and Western were consolidated by the Lackawanna Steel Company into one company,

10961-698: The same year, has the span of 90 m (295 ft) and crosses the valley of the Syrabach River. The difference between the two is that the Solkan Bridge was built from stone blocks, whereas the Friedensbrücke was built from a mixture of crushed stone and cement mortar. The world's largest arch bridge is the Chaotianmen Bridge over the Yangtze River with a length of 1,741 m (5,712 ft) and

11074-637: The simplest and oldest type of bridge in use today, and are a popular type. Some cantilever bridges also have a smaller beam connecting the two cantilevers, for extra strength. The largest cantilever bridge is the 549-metre (1,801 ft) Quebec Bridge in Quebec, Canada. With the span of 220 metres (720 ft), the Solkan Bridge over the Soča River at Solkan in Slovenia is the second-largest stone bridge in

11187-790: The time of the Warring States period , the oldest surviving stone bridge in China is the Zhaozhou Bridge , built from 595 to 605 AD during the Sui dynasty . This bridge is also historically significant as it is the world's oldest open-spandrel stone segmental arch bridge. European segmental arch bridges date back to at least the Alconétar Bridge (approximately 2nd century AD), while the enormous Roman era Trajan's Bridge (105 AD) featured open-spandrel segmental arches in wooden construction. Rope bridges ,

11300-740: The undertimbers of bridges all around the world are spots of prevalent graffiti. Some bridges attract people attempting suicide, and become known as suicide bridges . The materials used to build the structure are also used to categorize bridges. Until the end of the 18th century, bridges were made out of timber, stone and masonry. Modern bridges are currently built in concrete, steel, fiber reinforced polymers (FRP), stainless steel or combinations of those materials. Living bridges have been constructed of live plants such as Ficus elastica tree roots in India and wisteria vines in Japan. Unlike buildings whose design

11413-507: The variation of strength found in natural stone. One type of cement, called pozzolana , consisted of water, lime , sand, and volcanic rock . Brick and mortar bridges were built after the Roman era , as the technology for cement was lost (then later rediscovered). In India, the Arthashastra treatise by Kautilya mentions the construction of dams and bridges. A Mauryan bridge near Girnar

11526-433: The weld transitions . This results in a potential high benefit, using existing bridges far beyond the planned lifetime. While the response of a bridge to the applied loading is well understood, the applied traffic loading itself is still the subject of research. This is a statistical problem as loading is highly variable, particularly for road bridges. Load Effects in bridges (stresses, bending moments) are designed for using

11639-492: The whole system was re-gauged to standard gauge in one day. The New York, Lackawanna and Western Railroad was chartered on August 26, 1880, and opened on September 17, 1882, to continue the railroad from Binghamton west and northwest to Buffalo. The main line ran to the International Bridge to Ontario , and a branch served downtown Buffalo. A spur from Wayland served Hornellsville (Hornell). On December 1, 1903,

11752-632: The word for the card game of the same name is unknown.   The simplest and earliest types of bridges were stepping stones . Neolithic people also built a form of boardwalk across marshes ; examples of such bridges include the Sweet Track and the Post Track in England, approximately 6000 years old. Ancient people would also have used log bridges consisting of logs that fell naturally or were intentionally felled or placed across streams. Some of

11865-448: The world and the longest railroad stone bridge. It was completed in 1905. Its arch, which was constructed from over 5,000 tonnes (4,900 long tons; 5,500 short tons) of stone blocks in just 18 days, is the second-largest stone arch in the world, surpassed only by the Friedensbrücke (Syratalviadukt) in Plauen , and the largest railroad stone arch. The arch of the Friedensbrücke, which was built in

11978-407: Was dormant for several years following its incorporation. The company was chartered on March 14, 1849, and organized on January 2, 1850. On April 14, 1851, its name was changed to Lackawanna and Western Railroad . The line opened on December 20, 1851, and ran north from Scranton, Pennsylvania , to Great Bend, Pennsylvania , just south of Pennsylvania 's border with New York state . From Great Bend,

12091-499: Was forced to downgrade the Erie side, and even considered its abandonment west of Port Jervis. In the meantime, the EL was forced to run its long freights over the reconfigured Boonton Line, which east of Mountain View in Wayne, NJ meant running over the Erie's Greenwood Lake Branch, a line that was never intended to carry the level of freight traffic to which the EL would subject it. In 1972,

12204-572: Was fully merged into the DL&W. This line ran east–west across northern New Jersey, crossing the Warren Railroad at Washington and providing access to Jersey City without depending on the CNJ. The M&E tunnel under Bergen Hill opened in 1876, relieving the Morris and Essex Railroad and its owners, the Delaware, Lackawanna and Western Railroad, from having to use the New York, Lake Erie and Western Railway 's tunnel to reach Jersey City. Along with

12317-569: Was known as the Midland Bridge, a name recalled in Midland Avenue which descends from Passaic Street to the former West Arlington Station . The line ran between Sterling Forest at the New York state line to Croxton, Jersey City . The financially unstable Montclair Railway went into receivership , and in 1875 became the Montclair and Greenwood Lake Railway In 1878 the company was re-organized as

12430-519: Was opened; it is also the longest wooden bridge in Switzerland. The Arkadiko Bridge is one of four Mycenaean corbel arch bridges part of a former network of roads, designed to accommodate chariots , between the fort of Tiryns and town of Epidauros in the Peloponnese , in southern Greece . Dating to the Greek Bronze Age (13th century BC), it is one of the oldest arch bridges still in existence and use. Several intact, arched stone bridges from

12543-559: Was organized March 3, 1869, to connect the end of the original line at Great Bend, Pennsylvania , to Binghamton, New York , avoiding reliance on the Erie. The new line opened on October 1, 1871. By 1873, the company controlled the Lackawanna and Bloomsburg Railroad , a branch from Scranton southwest to Northumberland with trackage rights over the Pennsylvania Railroad 's Northern Central Railway to Sunbury . On March 15, 1876,

12656-496: Was organized in 1869, opened in 1870, and was immediately leased to the company, providing a short branch off the Oswego line from Chenango Forks to Greene . Also in 1870, the company leased the Utica, Chenango and Susquehanna Valley Railway , continuing this branch north to Utica , with a branch from Richfield Junction to Richfield Springs (fully opened in 1872). The "Valley Railroad"

12769-510: Was surveyed by James Princep . The bridge was swept away during a flood, and later repaired by Puspagupta, the chief architect of emperor Chandragupta I . The use of stronger bridges using plaited bamboo and iron chain was visible in India by about the 4th century. A number of bridges, both for military and commercial purposes, were constructed by the Mughal administration in India. Although large bridges of wooden construction existed in China at
