An arch bridge is a bridge with abutments at each end shaped as a curved arch . Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side, and partially into a vertical load on the arch supports. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today.
107-531: The Sunset Boulevard Bridge , also known as the Latah Creek Bridge , is a deck arch bridge in the northwestern United States that spans Latah Creek in Spokane, Washington . The bridge connects the neighborhoods of Browne's Addition on the east, and Downtown Spokane just beyond that, with West Hills to the west. Latah Creek, which passes under the bridge, separates the two neighborhoods. It
214-531: A company town in 1901, but it lacked most services. The housing stood empty for many years. In December 1900, the Lackawanna Coal & Coke Company was incorporated in Pennsylvania as a subsidiary to provide coke. Coal mines and coke ovens were opened in the company town of Wehrum, Pennsylvania , named after company general manager Henry Wehrum . The coal was not of high quality and there
321-577: A massive fire struck the Industrial Materials Recycling facility located in the plant's former galvanizing, cold mill, and hot mill buildings. The fire, which began at about 7 AM after a lightbulb exploded over flammable materials, was fought by more than 100 firefighters from Lackawanna, Buffalo, and Hamburg. Several explosions were caused by the fire, which collapsed the roof of the structure and caused other heavy damage to it. Federal and state environmental officials rushed to
428-443: A $ 64 million budget to make repairs to the aging bridge. The Sunset Boulevard Bridge is a 1,070-foot long concrete arch bridge made up of seven semi-circular, or Roman, arches. The arches are of varying sizes, with the two largest spanning 150 feet in length, with 135-foot arches on either side of those, one 128-foot arch to the west, and a pair of 54-foot abutment arches on each end. Unlike Spokane's other large concrete arch bridge,
535-415: A 10 percent wage hike. The union struck again from May 11, 1902, to October 23, 1902, and won a second wage increase as well as better working conditions. A second factor was the increasing cost of shipping iron ore to Scranton and a lack of rail lines from Scranton to the company's newly emerging markets. In 1899, Lackawanna Iron and Steel Company move its facilities to West Seneca, New York , drawn by
642-464: A Canadian owned manufacturer of steel tubing, built and opened a new plant in 2013 in the western portion of the facility. Three small fires struck the former Lackawanna works between 2014 and 2016. The first fire occurred in 2014, with additional fires in February and October 2016. All three fires occurred at a mulch-grinding facility owned and operated by Zoladz Construction. On November 9, 2016,
749-561: A bank and the City of Scranton's gas and water works . During the 1870s, American railroads began buying track rails again from Europe. The reason was the high quality of steel rail produced in Europe, thanks to the invention in 1855 of the Bessemer process for steelmaking. This drastically reduced the fuel costs and amount of time needed to make steel, as well as significantly improving
856-538: A body of miners from the mines one afternoon, he was attacked by a mob and in the ensuing fight, two of the rioting strikers were killed. The state militia was called in to restore order, protect the strikebreakers, and help reopen the mines. The strike began to collapse in April 1871 as strikebreakers opened more mines, and the strikers and their families began to starve. Violence flared again in early May, and state troops were once more called to restore order. Within
963-408: A cousin from Connecticut , and John Howland , a banker and businessman from New York . The Scranton family retained 51.6 percent of the company's stock. Quality control problems plagued the company and nearly drove it to bankruptcy again. By summer 1844, the furnace averaged five to seven tons of pig iron a day. Scrantons and Grant initially used the pig iron to produce nails and iron plates, but
1070-512: A deck arch bridge. Any part supported from arch below may have spandrels that are closed or open. The Sydney Harbour Bridge and the Bayonne Bridge are a through arch bridge which uses a truss type arch. Also known as a bowstring arch, this type of arch bridge incorporates a tie between two opposite ends of the arch. The tie is usually the deck and is capable of withstanding the horizontal thrust forces which would normally be exerted on
1177-533: A few days, the strike had largely been broken and most miners returned to work. William Scranton was arrested twice for his role in leading the strikebreakers, but acquitted at trial each time. A second large strike hit the company in 1877. The Long Depression began with the Panic of 1873 and did not end until 1896. By 1877, thousands of miners, steel workers, and railroad employees were out of work and wages had been slashed repeatedly. On July 23, 1877, workers in

#17327932534241284-462: A greater passage for flood waters. Bridges with perforated spandrels can be found worldwide, such as in China ( Zhaozhou Bridge , 7th century). Greece ( Bridge of Arta , 17th century) and Wales ( Cenarth Bridge , 18th century). In more modern times, stone and brick arches continued to be built by many civil engineers, including Thomas Telford , Isambard Kingdom Brunel and John Rennie . A key pioneer
1391-542: A merger which would create a billion-dollar company. Bethlehem Steel said it would spend $ 10 million improving the Lackawanna mills, which were described as "obsolete" due to a lack of investment. The combined company controlled about 10 percent of the steel output of the United States, while U.S. Steel controlled about 45 percent. A lengthy antitrust investigation followed. The United States Senate asked
1498-499: A merger with the Cambria Steel Company , Newport News Shipbuilding and Drydock Company , Youngstown Sheet and Tube , and Inland Steel . But despite the agreement of the steel companies, federal regulators, and others, the banks carrying the debt for these companies refused to approve the merger and the plan was dropped. The company's financial status varied considerably in the late 1910s. The stock set new highs and
1605-443: A nationwide strike in the fall of 1919 to organize the entire steel industry. The strike began on September 22, with the union claiming 8,000 of the plant's 9,000 workers had struck and the company asserting only half the workers had walked out. The same day, three riots broke out in the city. Late in the afternoon, during the shift change, a crowd of 7,000 pro-union strikers and supporters began throwing rocks, bottles and debris at
1712-447: A number were segmental arch bridges (such as Alconétar Bridge ), a bridge which has a curved arch that is less than a semicircle. The advantages of the segmental arch bridge were that it allowed great amounts of flood water to pass under it, which would prevent the bridge from being swept away during floods and the bridge itself could be more lightweight. Generally, Roman bridges featured wedge-shaped primary arch stones ( voussoirs ) of
1819-724: A primary arterial as classified by the city. It is the only arterial crossing Latah Creek and one of just two arterials crossing Latah Creek or the Spokane River, on the west side of the city. It connects the West Hills neighborhood on the west with Browne's Addition, and the city center, on the east. Arch bridge Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge
1926-448: A quantity of fill material (typically compacted rubble) above the arch in order to increase this dead-weight on the bridge and prevent tension from occurring in the arch ring as loads move across the bridge. Other materials that were used to build this type of bridge were brick and unreinforced concrete. When masonry (cut stone) is used the angles of the faces are cut to minimize shear forces. Where random masonry (uncut and unprepared stones)
2033-415: A result, masonry arch bridges are designed to be constantly under compression, so far as is possible. Each arch is constructed over a temporary falsework frame, known as a centring . In the first compression arch bridges, a keystone in the middle of the bridge bore the weight of the rest of the bridge. The more weight that was put onto the bridge, the stronger its structure became. Masonry arch bridges use
2140-430: A three-hinged bridge has hinged in all three locations. Most modern arch bridges are made from reinforced concrete . This type of bridge is suitable where a temporary centring may be erected to support the forms, reinforcing steel, and uncured concrete. When the concrete is sufficiently set the forms and falseworks are then removed. It is also possible to construct a reinforced concrete arch from precast concrete , where
2247-453: A year, the company's assets had expanded to include three furnaces, a steel-making puddling mill , a foundry , two blacksmith shops, two carpentry shops, a saw mill , a grist mill , company store, 200 dwellings (to house workers), a boarding house , iron ore mines, coal mines, a tavern , and a hotel . The company also expanded into the railroad business in 1853. Needing a secure way of getting products to market without having to pay

#17327932534242354-428: Is a masonry, or stone, bridge where each successively higher course (layer) cantilevers slightly more than the previous course. The steps of the masonry may be trimmed to make the arch have a rounded shape. The corbel arch does not produce thrust, or outward pressure at the bottom of the arch, and is not considered a true arch . It is more stable than a true arch because it does not have this thrust. The disadvantage
2461-573: Is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks , the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction. A list of Roman bridges compiled by
2568-432: Is that this type of arch is not suitable for large spans. In some locations it is necessary to span a wide gap at a relatively high elevation, such as when a canal or water supply must span a valley. Rather than building extremely large arches, or very tall supporting columns (difficult using stone), a series of arched structures are built one atop another, with wider structures at the base. Roman civil engineers developed
2675-402: Is used they are mortared together and the mortar is allowed to set before the falsework is removed. Traditional masonry arches are generally durable, and somewhat resistant to settlement or undermining. However, relative to modern alternatives, such bridges are very heavy, requiring extensive foundations . They are also expensive to build wherever labor costs are high. The corbel arch bridge
2782-784: The Federal Trade Commission (FTC) and the Justice Department to investigate the merger the day after it was announced, which the FTC did on May 14. As the merger was approved by the two companies in mid-May, the Senate and FTC each conducted separate investigations. On June 5, 1922, the FTC issued a report concluding that the merger was in violation of the Sherman Antitrust Act . However, United States Attorney General Harry M. Daugherty overruled
2889-668: The Great Railroad Strike of 1877 already raging) Hayes agreed to send them at the governor's request. Violence broke out on July 29: The head house of the Penn Coal Co.'s short-line railroad was firebombed, a local bridge was burned, and many of the coal mines owned by the Lackawanna Iron and Coal Co. were flooded. The next day McKune threatened to call out the federal troops, but also offered his own services as an arbitrator. The two sides met throughout
2996-664: The Midland Railroad and the Sussex Railroad , of which he was part-owner. Taylor wanted to link his railroads with the Scranton-owned Delaware & Lackawanna, and believed the Lackawanna Iron and Coal Co. could turn his pig iron into finished steel—but only if the company adopted the Bessemer process. Together, Moses Taylor and W.W. Scranton convinced the company's other investors to adopt
3103-563: The Pan-American Exposition , and many property owners assumed the land purchases were for the Exposition. Construction of the massive new steel mill began on July 14, 1900, and nine months later equipment was arriving from Scranton. The company dredged a ship canal and built miles of track to link the plant with the railroads which would bring iron ore and coke to the plant. Lackawanna Iron and Steel began building
3210-442: The 1860s, bringing new technological innovations to the firm. William Walker Scranton , son of Joseph Scranton, was born in 1844. At the age of 23, William Walker Scranton had already become superintendent of one of the Lackawanna Iron and Coal Company's steel mills. After Joseph Scranton's death in 1872, William took control of the entire family business empire, which now included (in addition to large numbers of coal and iron mines)
3317-470: The 20th century. In the 1940s, the Lackawanna steel mill employed over 20,000 people, and was the world's largest steel factory. In the 1970s and 1980s, Bethlehem Steel allowed the Lackawanna Steel plant to become obsolete. Foreign competition made it financially impossible to continue to manufacture most of the products produced at Lackawanna. Bethlehem Steel also disliked the high tax rates of

3424-453: The Bessemer process in 1875, and to merge the Taylor and Scranton railways in 1881. The first "blow" (or pouring of molten steel from the Bessemer furnace into molds) occurred on October 23, 1875, and the first Bessemer steel rolled in the mill on December 29, 1875. During the 1870s and the recession, the Lackawanna Iron and Coal Company suffered from significant labor problems. The company
3531-531: The EPA entered into an administrative consent order requiring Bethlehem Steel to identify the nature and extent of any releases of hazardous waste and mitigate any emergency situations that might be discovered during the course of the investigations. Bethlehem Steel and its successor corporations have been submitting RCRA Facility Investigation (RFI) reports since then. Although the RFI was due to be completed in 2004, it still
3638-411: The FTC on June 22. The merger finally took effect on October 10, 1922. Six decades later, financial analysts observed that Bethlehem Steel probably purchased Lackawanna Steel for less than half what the company was worth. Over the next decade, Bethlehem Steel spent more than $ 40 million modernizing the Lackawanna site. Lackawanna continued to be a center for the manufacture of steel throughout most of
3745-538: The Lackawanna Iron and Coal Co. By 1880, the company was the second-largest producer of iron in the United States. But, Scranton wanted the company to expand, a proposal which the board of directors rejected in 1881. Scranton quit the company and formed the Scranton Steel Co. with his brother, Walter Scranton, in 1881. Within 10 years, the Scranton Steel Co. had become so successful that the Lackawanna Iron and Coal Co. entered into negotiations to merge with
3852-588: The Monroe Street Bridge, which was constructed contemporaneously and used a flattened arch, the Sunset Boulevard Bridge was designed with semi-circular arches due to its specific setting. The semi-circular arches exert thrust in a way better suited for the large and heavier than usual piers required for the sandy ground along Latah Creek that they would be built upon. Each of the five main arches support four spandrel arches, while
3959-416: The Sunset Boulevard Bridge was bypassed by the adjacent I-90 bridge, which carried the new interstate into and through the city. As the bridge approached its 100th birthday, the City of Spokane commissioned a study from CH2M Hill on options for rehabilitating the bridge. The 2012 study cost $ 631,000, which was provided by federal grants. In the years prior to the study, deterioration on the bridge deck led
4066-542: The Sunset Highway starting from the latter's opening in 1915. Sunset Highway was known by a number of official names, such as State Road No. 2 , one of Washington's first highways to cross the state west-to-east, and later as U.S. Route 10 . The bridge carried the primary west-to-east highway into Spokane, by many names and numbers, until the arrival of the Interstate Highway System . In 1963,

A tied-arch bridge can also be a through arch bridge. An arch bridge with hinges incorporated to allow movement between structural elements. A single-hinged bridge has a hinge at the crown of the arch , a two-hinged bridge has hinges at both springing points and
4280-793: The acclaimed Florentine segmental arch bridge Ponte Vecchio (1345) combined sound engineering (span-to-rise ratio of over 5.3 to 1) with aesthetical appeal. The three elegant arches of the Renaissance Ponte Santa Trinita (1569) constitute the oldest elliptic arch bridge worldwide. Such low rising structures required massive abutments , which at the Venetian Rialto bridge and the Fleischbrücke in Nuremberg (span-to-rise ratio 6.4:1) were founded on thousands of wooden piles, partly rammed obliquely into

At 5:50 p.m., after being pelted with rocks and glass bottles, company police fired more than 50 12- gauge shotguns blasts into the crowd. "[F]rantic signals to cease firing" by the Lackawanna Police, who were in the middle of the crowd trying to restore order, "were disregarded by the plant guards". The company guards killed two and injured three. The plant remained closed through September 28, with only 500 employees reporting for work. Lackawanna Steel, which had employed only 72 African Americans prior to

4494-405: The amount of taxes paid by Bethlehem Steel fell from 66 percent of the city's revenue to just 8 percent. In addition, the city owed the company more than $ 5 million in tax overcharges. The United Steelworkers later successfully sued Bethlehem Steel for prematurely terminating the fringe benefits of the laid-off steelworkers. Bethlehem Steel, which maintained a small presence in Lackawanna after
4601-416: The arch and the deck is known as the spandrel . If the spandrel is solid, usually the case in a masonry or stone arch bridge, the bridge is called a closed-spandrel deck arch bridge . If the deck is supported by a number of vertical columns rising from the arch, the bridge is known as an open-spandrel deck arch bridge . The Alexander Hamilton Bridge is an example of an open-spandrel arch bridge. Finally, if
4708-400: The arch is built in two halves which are then leaned against each other. Many modern bridges, made of steel or reinforced concrete, often bear some of their load by tension within their structure. This reduces or eliminates the horizontal thrust against the abutments and allows their construction on weaker ground. Structurally and analytically they are not true arches but rather a beam with
4815-422: The arch supports the deck only at the top of the arch, the bridge is called a cathedral arch bridge . This type of bridge has an arch whose base is at or below the deck, but whose top rises above it, so the deck passes through the arch. The central part of the deck is supported by the arch via suspension cables or tie bars, as with a tied-arch bridge . The ends of the bridge may be supported from below, as with
4922-568: The area were organized by the American Federation of Labor (although Lackawanna officials estimated there were far fewer union members). Lackawanna Steel officials, fearing that immigrant union members would become violent, asked for and received protection from the New York State Police . The Lackawanna Steel organizing drive was part of a nationwide organizing effort by the union, and the union resolved to launch
5029-684: The area's easy access to Great Lakes shipping and the numerous rail lines in the area. Scranton decided to move his operation to the Buffalo suburb, located on Lake Erie. To avoid speculation in land, the Lackawanna Steel Company employed John J. Albright , president of the Ontario Power Company , to purchase land on its behalf. Scranton, Albright and several others met in Buffalo on March 23, 1899, to discuss
5136-500: The back as they tried to flee. Mayor McKune, although badly injured, helped restore order around 2 p.m. The following day, 3,000 federal troops arrived from Pittsburgh and entered the city. Martial law was imposed, and the strike ended several uneventfully weeks later with no agreement. The sheriff and several posse members were arrested and tried on the charge of manslaughter , but were acquitted. The company's labor troubles were supplanted by an internal struggle for control within
5243-418: The bar, rod and wire plants from Bethlehem and began manufacturing automobile steering columns under its subsidiary, Bar Technologies. This operation has since been taken over by Republic Steel , which manufactures hot rolled bars and coils and employed 270 people in 2018. This plant, which was shut down in 2023, represented the last steel production in former Bethlehem facilities in Lackawanna. Welded Tube,
5350-625: The bridge an unusually flat profile unsurpassed for more than a millennium. Trajan's bridge over the Danube featured open- spandrel segmental arches made of wood (standing on 40 m-high (130 ft) concrete piers). This was to be the longest arch bridge for a thousand years both in terms of overall and individual span length, while the longest extant Roman bridge is the 790 m-long (2,590 ft) long Puente Romano at Mérida . The late Roman Karamagara Bridge in Cappadocia may represent
5457-414: The bridges. Prior to the construction of the present Sunset Boulevard Bridge, a timber railroad trestle crossed Latah Creek at the same location. The old timber trestle was demolished, but the railroad leading to the bridge remained during construction, and was used to deliver the concrete to the construction site of the current bridge. Construction began on the Sunset Boulevard Bridge in 1911, making it

Two other Pennsylvanians, Sanford Grant, a Belvidere, New Jersey , businessman, and Philipp Mattes, a bank manager from Easton, Pennsylvania , also invested in the new company, named Scranton, Grant, and Co. Henry bought 503 acres (2.04 km ) near Slocum's Hollow, and began building the furnace. The blast furnace

The study found that the bridge arches, particularly in the center where they were designed to carry rail traffic, were still strong. They determined the bridge was still safe, but that the deck would need to be replaced, similar to what was done to the Monroe Street Bridge a few years prior to the study. In July 2023, the Spokane City Council approved
5778-563: The cold-short ore they used was ideal for manufacturing rail tracks, the Scrantons sought new investors whose money would permit it to build a rail track rolling mill. Benjamin Loder , president of the New York and Erie Railroad ; industrialist William E. Dodge ; and eight others invested $ 90,000 in the firm. The Scrantons and Grant reorganized again on November 7, 1846, and began calling
5885-618: The company Scrantons and Platt. Grant was bought out, and Howland asked to have his investment returned. The company quickly began turning out rails for the Erie Railroad, becoming the first company in the United States to mass-produce T rails . The firm's decision to manufacture rail tracks changed the fundamental nature of transportation in the United States, accelerated rail use, and eliminated American dependence on England for railroad track. Rail production began in August 1847, and
5992-412: The company continued to see wide swings in profitability. In 1920, the company's profits fell again, and a merger was rumored. The company declared itself profitable in late 1920, and then reported large deficits in 1921. Rumors that the company might sell itself emerged in mid-October 1921, but in fact the firm went on a buying spree and snapped up a pig iron manufacturer and a steel bridge maker. Over
6099-499: The company doubled its profits in 1917 and the first half of 1918, but in late 1918 and throughout 1919 the company fell on hard financial times. Although Lackawanna Steel had moved to New York in part to avoid unionization, the unions followed the company. An attempt to unionize the company was made in 1919 by the Amalgamated Association of Iron and Steel Workers . Lackawanna's Democratic mayor , John Toomey,
6206-439: The company lost between $ 6,000 and $ 7,000 in the year ending June 1843, but the total may have been as high as $ 10,000. George Scranton took control of the works from William Henry, and twice rebuilt the furnace. Near bankruptcy, the partners sought new sources of capital. In May 1843, a $ 20,000 loan permitted the company to continue operating. After many failures and two years of low-level and low-quality production of pig iron,
6313-495: The company soon employed more than 800 mostly Welsh , Irish , and German workers. Shipments of rail track were hauled overland through the snow to the New York and Erie Railroad, arriving just in time to save the line from bankruptcy. In 1851, Slocum's Hollow changed its name to Scranton in honor of the owners of the iron works. The Scrantons had won approval from the townspeople some years before to rename Slocum's Hollow as
6420-534: The company's guards, and city police were called in to break up the disturbance. At 7:20 p.m., a crowd of 3,000 unionists and their supporters intercepted a group of 200 strikebreakers leaving the plant, and chased them through the surrounding neighborhood before police intervened and stopped them. Later in the evening, a small crowd of men beat a man who announced he would work for the company's private police force, and city police once more were called in. On September 23, 1919, company police clashed twice late in
6527-689: The company's original location. When the company moved to a suburb of Buffalo, New York , in 1902, it stimulated the founding of the city of Lackawanna . At the beginning of the 1800s, the Lackawanna Valley in Pennsylvania was rich in anthracite coal and iron deposits. Brothers George W. Scranton and Seldon T. Scranton moved to the valley in 1840 and settled in the five-house town of Slocum's Hollow in present-day Scranton, Pennsylvania , to establish an iron forge. Although Europeans had been making steel for nearly three centuries,

#17327932534246634-415: The creation of extensive tracts of extremely substandard housing and severe public health problems (including outbreaks of cholera , typhoid and influenza ). To save the town, West Senecans proposed separating the area around the steel mill as its own incorporated municipality. Lackawanna Steel opposed the incorporation of the proposed municipality (to be named Lackawanna), but it relented in 1909 after

Although a majority of the steel workers appeared ready to accept the tentative agreement, a mob of 6,000 men formed on August 1 in downtown Scranton and resolved to reject it. When McKune appeared outside the mayor's office to try to calm the mob, shots were fired. McKune was clubbed and stoned . His lower jaw broken and his upper jaw fractured, McKune tried to flee but

This type is still used in canal viaducts and roadways as it has a pleasing shape, particularly when spanning water, as the reflections of the arches form a visual impression of circles or ellipses. This type of bridge comprises an arch where the deck is completely above the arch. The area between
6955-554: The earliest surviving bridge featuring a pointed arch. In medieval Europe, bridge builders improved on the Roman structures by using narrower piers , thinner arch barrels and higher span-to-rise ratios on bridges. Gothic pointed arches were also introduced, reducing lateral thrust, and spans increased as with the eccentric Puente del Diablo (1282). The 14th century in particular saw bridge building reaching new heights. Span lengths of 40 m (130 ft), previously unheard of in

A more complete survey by the Italian scholar Vittorio Galliazzo found 931 Roman bridges, mostly of stone, in as many as 26 countries (including former Yugoslavia ). Roman arch bridges were usually semicircular , although

They reorganized the combined subsidiary into the Delaware, Lackawanna and Western Railroad , beginning vertical integration of their industry. A second generation of Scrantons took control of the Lackawanna Iron and Coal Company in
7276-483: The firm began producing significant amounts of pig iron in 1843. The company installed a rolling mill , five reverberatory furnaces , 20 nail manufacturing machines, and one spike manufacturing machine. Needing more cash, the company was reorganized in September 1846, taking the new name of Scrantons and Grant. New partners were brought in, including Joseph H. Scranton , a cousin from Georgia , Erastus C. Scranton,
7383-498: The firm. The two companies merged on January 9, 1891, forming the Lackawanna Iron and Steel Company. Although the merger created nearly $ 1.2 million in debt for the new company, Lackawanna Iron & Steel proved to be so financially successful that it paid off the debt within a year. At the turn of the century, the Lackawanna Iron and Steel Company began to consider moving out of the Scranton area. The company's economic condition
7490-522: The first steel in early 1903. The company's property in Scranton was sold to the Lackawanna and Wyoming Valley Railroad , which scrapped all the remaining equipment and tore down all the buildings except for the oldest stone blast furnaces. The economic coup which William Walker Scranton had engineered did not please the board of directors, however, who replaced him in late 1904 with Edward A. Clarke. The company continued to expand, and in 1906 bought
7597-499: The grounds to counteract more effectively the lateral thrust. In China, the oldest existing arch bridge is the Zhaozhou Bridge of 605 AD, which combined a very low span-to-rise ratio of 5.2:1, with the use of spandrel arches (buttressed with iron brackets). The Zhaozhou Bridge, with a length of 167 feet (51 m) and span of 123 feet (37 m), is the world's first wholly stone open-spandrel segmental arch bridge, allowing
7704-443: The history of masonry arch construction, were now reached in places as diverse as Spain ( Puente de San Martín ), Italy ( Castelvecchio Bridge ) and France ( Devil's bridge and Pont Grand ) and with arch types as different as semi-circular, pointed and segmental arches. The bridge at Trezzo sull'Adda , destroyed in the 15th century, even featured a span length of 72 m (236 ft), not matched until 1796. Constructions such as
7811-533: The hot-blast technique in the U.S. was carried out in 1835 at Oxford Furnace in Warren County, New Jersey , by William Henry, Seldon Scranton's father-in-law . By 1838, Henry had moved to the Lackawanna Valley, where he was experimenting with using anthracite coal in steelmaking. The Scrantons and Henry formed a partnership in 1840 to develop a hot blast furnace that used anthracite coal in
7918-584: The huge New York steel mill's aging equipment. In 1922, Lackawanna Steel Co. was acquired by the Bethlehem Steel Company, ending the company's 62-year independence. Merger rumors had plagued the company for several years by then. Rumors of an impending merger among two or more of the "Little Steel" companies—the seven steel companies largest in size next to U.S. Steel—continued in November and December 1921 and into 1922. In late April 1922,
8025-501: The iron and steel mills owned by the Lackawanna Iron and Coal Co. struck, seeking a 25 percent wage increase. The strike spread to rail workers the next day, and on July 25 the company's mine workers also walked out and demanded a similar wage increase. The company asked Scranton Mayor Robert McKune for police protection the same day, and McKune asked Governor John F. Hartranft for troops. On July 26, Governor Hartranft asked President Rutherford B. Hayes for federal troops, and (with
8132-478: The large Pennsylvania coal mining firm of J.W. Ellsworth Company. Lackawanna Steel Co. had a rocky relationship with the town of West Seneca. The company demanded large investments in sewer, water, gas and road improvements but refused to pay for them (even though the company was much wealthier than the town). The large influx of workers from the company's old Pennsylvania site swelled the Town's population, leading to
8239-460: The mass layoffs in 1982, ended coke production at the Lackawanna site in 2001, leaving a galvanized steel finishing plant employing about 250 people. Upon Bethlehem's bankruptcy in 2003, the plant was acquired by International Steel Group . It merged with Mittal Steel Company in 2004. In 2006, the plant came under the ownership of ArcelorMittal , which eventually ended its operations at Lackawanna in 2009. In 1993, Veritas Capital purchased one of
8346-404: The next several years, the Lackawanna plant continued to expand physically, its works now rambling over more than two miles (3 km) of shoreline and spilling over into the nearby town of Hamburg . Lackawanna Steel paid about 75 percent of the taxes in the city of Lackawanna, effectively controlling city government. In 1922, Lackawanna Steel reported very large deficits, driven primarily by
8453-479: The only ones to construct bridges with concrete , which they called Opus caementicium . The outside was usually covered with brick or ashlar , as in the Alcántara Bridge . The Romans also introduced segmental arch bridges into bridge construction. The 330 m-long (1,080 ft) Limyra Bridge in southwestern Turkey features 26 segmental arches with an average span-to-rise ratio of 5.3:1, giving
8560-682: The processes for creating blister steel and crucible steel were slow and extremely expensive. The Scrantons focused instead on manufacturing pig iron , using a blast furnace . They wanted to take advantage of a recent technological innovation in iron smelting, the " hot blast ". Developed in Scotland in 1828, the hot blast preheats air before it is pumped through molten iron, substantially lowering fuel needs. The Scrantons also intended to experiment with using anthracite coal to make steel, rather than existing methods which used charcoal or bituminous coal . The most likely successful first use of
8667-467: The purchase of land. The group explored several nearby sites on March 24, and that same day chose an undeveloped shoreline area on Lake Erie in what was then the western part of the Town of West Seneca. Albright began purchasing land on April 1, 1899, and by the end of the month had obtained nearly all the required property for the extremely low price of $ 1.1 million. Albright was often accompanied on his purchasing visits by John G. Milburn , President of
8774-475: The quality of the ore—" red-short " rather than the required close-grained "cold-short"—prevented the smelting of high-quality pig iron. The company's finances spiraled downward. Railroad networks in the U.S. were tripling in size during the 1840s, and the railroads required large quantities of rails . But until 1844, the U.S. had no factories capable of manufacturing rails, and all rails had to be imported and shipped by sea from Great Britain . Realizing that
8881-521: The quality of the steel produced. Scranton took a leave of absence from the firm and secretly went to Britain and then Germany, where he became a puddler and learned the secrets of making "Bessemer steel". But Scranton could not convince his business partners to adopt the Bessemer process. Meanwhile, industrialist Moses Taylor , a protégé of John Howland's, had organized the Franklin Iron Company to supply pig iron for rail tracks to
8988-639: The same in size and shape. The Romans built both single spans and lengthy multiple arch aqueducts , such as the Pont du Gard and Segovia Aqueduct . Their bridges featured from an early time onwards flood openings in the piers, e.g. in the Pons Fabricius in Rome (62 BC), one of the world's oldest major bridges still standing. Roman engineers were the first and until the Industrial Revolution
9095-423: The scene to monitor health hazards from the blaze, which caused the evacuation of a nearby neighborhood due to fire and the closure of two elementary schools due to smoke dangers. Burning debris fell on the city of Lackawanna and town of Hamburg. The fire was contained but still burning on the morning of November 10, requiring the continued evacuation of the neighborhood and the schools. The Lackawanna Steel plant
9202-418: The second of Spokane's large, concrete arch bridges, after the shorter-in-length but taller Monroe Street Bridge . It was opened to traffic two years later in 1913. The bridge would become seen as ahead of its time in terms of the traffic it would carry. It was built to handle highway level traffic in the earliest days of the automobile, long before highways were on the map. The Sunset Boulevard Bridge carried
9309-475: The seven "Little Steel" firms began to openly discuss the merger of two or more of the companies as a means of challenging U.S. Steel. The chief executives and creditors of these firms visited one another's plants in order to appraise them and assess the financial viability of each company. Among those visited was the Lackawanna Steel Company plant in upstate New York. On May 11, 1922, Lackawanna Steel announced it had agreed to be purchased by Bethlehem Steel in
9416-402: The shape of an arch. See truss arch bridge for more on this type. A modern evolution of the arch bridge is the long-span through arch bridge . This has been made possible by the use of light materials that are strong in tension such as steel and prestressed concrete. "The Romans were the first builders in Europe, perhaps the first in the world, fully to appreciate the advantages of the arch,
9523-528: The state of New York, and did not want to spend the millions of dollars in air and water pollution abatement which were required by state and federal authorities. The company built a new facility in Burns Harbor, Indiana , and stopped investing in new steel production methods at Lackawanna. In 1982, Bethlehem Steel announced the closing of nearly all production at the Lackawanna Steel plant in New York. Bethlehem Steel, like many American steel companies,
9630-586: The strike and some workers stayed out until June 1920. Nearly all the black strikebreakers were fired after the strike when the company took back its striking workers. The organizing campaign failed, but the company was eventually organized by the Steel Workers Organizing Committee in the late 1930s after passage of the National Labor Relations Act in 1935. In the two years after the organizing drive,
9737-434: The strike, hired several thousand black strikebreakers and brought them to the city to maintain operations. Outraged, union workers turned to political activity. Toomey lost re-election in the city's regularly scheduled mayoral race on November 4, 1919, and John H. Gibbons , a Socialist , was elected. Although the national organizing committee called off the strike on January 8, 1920, Gibbons' election reinvigorated
9844-448: The town of Harrison, in honor of U.S. President William Henry Harrison . The town was renamed Scrantonia in 1850, and the name shortened in 1851 to Scranton. The swiftly growing iron mill led to similar growth in Scranton, whose population soared from a few hundred in 1850 to 9,000 in 1860 to 35,000 in 1870. In 1853, the firm reorganized, doubling its capital investment and adopting the name Lackawanna Iron and Coal Company. Within
9951-572: The two abutment arches have closed spandrels. These spandrels support the 45-foot roadway above, which was originally topped with ornamental pillars made of cast iron, though they were removed sometime before 2014. Steel for the structure was manufactured by the Lackawanna Steel Company and the concrete was supplied by the Inland Portland Cement Company. The bridge carries two lanes of Sunset Boulevard,
10058-420: The two-year-long Panic of 1907 nearly bankrupted the Town of West Seneca and imperiled the company's operations. The creation of U.S. Steel in 1901 supplanted Lackawanna Steel as the country's largest steel manufacturer. A number of the so-called "independent" steel companies considered merger over the next two decades as a response to U.S. Steel's formation. In late 1915, Lackawanna Steel nearly consummated
10165-525: The vault and the dome." Lackawanna Steel Company The Lackawanna Steel Company was an American steel manufacturing company that existed as an independent company from 1840 to 1922, and as a subsidiary of the Bethlehem Steel company from 1922 to 1983. Founded by the Scranton family, it was once the second-largest steel company in the world (and the largest company outside the U.S. Steel trust). Scranton, Pennsylvania , developed around
10272-402: Was Jean-Rodolphe Perronet , who used much narrower piers, revised calculation methods and exceptionally low span-to-rise ratios. Different materials, such as cast iron , steel and concrete have been increasingly used in the construction of arch bridges. Stone, brick and other such materials are strong in compression and somewhat so in shear , but cannot resist much force in tension . As
10379-474: Was built 113 years ago in 1911 by the city of Spokane, and was designed by Morton McCartney & J.F. Cunningham, with J.F. Greene serving as the construction engineer. It is the northernmost of three bridges which cross Latah Creek in its immediate area. High Bridge is located to the south, and carries a BNSF railroad. Interstate 90 crosses Latah Creek just to the south of the rail bridge. All three pass over High Bridge Park , which takes its name from
10486-430: Was completed in the early autumn of 1841. The company's first effort at smelting iron was not successful. Many problems plagued the iron mill, including a furnace that was not hot enough, water that ran too low in the nearby creek to turn the waterwheel-powered bellows (and thus did not provide enough air to the furnace), unsuccessful experiments with charge mixtures, clogged tuyeres , and more. George Scranton estimated
10593-544: Was declared a Superfund site by the Environmental Protection Agency (EPA) in 1988 after the EPA conducted a Resource Conservation and Recovery Act (RCRA) Facility Assessment of the plant. The state of New York subsequently declared it a Class 2 Inactive Hazardous Waste Site, indicating the site poses a significant potential threat to human health and the environment. In August 1990, Bethlehem Steel (operating as Tecumseh Redevelopment, Inc.) and
10700-490: Was deteriorating; in September 1899, Andrew Carnegie wrote, "My view is that sooner or later Harrisburg, Sparrows Point, and Scranton will cease to make rails, like Bethlehem. The autumn of last year seemed as good a time to force them out of business as any other." Labor costs were rising. In 1897, the United Mine Workers organized most workers at the coal and iron mines, who successfully struck in 1900 for
10807-475: Was encountering significant financial problems. Although the company made several public attempts to reassess the plant's viability and keep the plant open in the late 1970s, closure was a foregone conclusion for many. On June 25, 1982, Bethlehem Steel announced it would close the Lackawanna facility and lay off its remaining 10,000 workers in six weeks. The news meant the laying off of an additional 8,000 workers in Lackawanna, West Seneca, and Buffalo. An attempt
10914-461: Was knocked unconscious when a member of the mob hit him in the head with a hammer. A few minutes later, the county sheriff and a hastily assembled posse arrived and fired shots over the heads of the crowd to try to disperse the mob. Several people in the crowd returned fire, wounding the sheriff and a member of the posse. The posse fired several volleys into the crowd, killing four and wounding around 20. Many of those killed and injured were shot in
11021-498: Was little production after 1904. The town was abandoned by the 1930s. On February 14, 1902, the company was reorganized into the Lackawanna Steel Company. It was the largest independent steel company in the world at the time. Stock worth $ 60 million was issued, with $ 20 million of the newly raised capital paying off the construction of the new mill. The mill received its first shipment of iron ore on December 23, 1902. The plant's 6,000 workers (2,000 of whom came from Scranton) blew
11128-613: Was made to interest the Buffalo-based Gibraltar Steel Corporation in the plant, but this effort failed. The Lackawanna Steel plant stopped most of its operations on October 15, 1982. The company laid off workers in waves before the final closure, and transferred many others. On the day the plant stopped most of its operations, more than 6,000 workers lost their jobs (most of them high-paying). The city of Lackawanna's 22,700 people faced extremely large tax increases just to maintain basic services, as
11235-571: Was not complete as of June 2008. The plant was also declared a brownfield in 2003 under the Small Business Liability Relief and Brownfields Revitalization Act of 2002. While this made the city of Lackawanna eligible for federal assistance money to redevelop part of the site, a cooperative agreement had not been signed as of May 2006. The city of Lackawanna redeveloped some of the former Lackawanna Steel plant land into small business zones, bringing about 700 jobs back to
11342-493: Was one of many which cut wages in its coal mines 30 percent in 1870. The Delaware & Lackawanna, the company railroad, also sharply cut wages for its workers. The first week of January 1871, a nascent mine workers union, the Workingmen's Benevolent Association , went on strike for higher wages. Scranton helped break the strike by personally leading strikebreaking miners to and from the mines each day. While escorting
11449-482: Was supported financially by the Lackawanna Steel Co. Toomey initiated a vicious red-baiting campaign to smear the union organizing effort as communist -inspired and led. The company fired hundreds of workers in the summer and fall of 1919 for being union members or union sympathizers. Nonetheless, by 1919 more than 18,000 steelworkers at Lackawanna Steel and five other, smaller metallurgical firms in
