123-639: The Ambassador Bridge is an international suspension bridge across the Detroit River that connects Detroit, Michigan , United States, with Windsor, Ontario , Canada. Opened in 1929, the toll bridge is the busiest international border crossing in North America in terms of trade volume, carrying more than 25% of all merchandise trade between the United States and Canada by value. A 2004 Border Transportation Partnership study showed that 150,000 jobs in
246-410: A cable-stayed bridge in which the deck is in compression. Cable-stayed bridges and suspension bridges may appear to be similar, but are quite different in principle and in their construction. In suspension bridges, large main cables (normally two) hang between the towers and are anchored at each end to the ground. The main cables, which are free to move on bearings in the towers, bear the load of
369-519: A collective bargaining agreement with the unions because the violence, work disruptions, and bitter stalemates could not go on forever. But Ford, who still had the final veto in the company on a de facto basis even if not an official one, refused to cooperate. For several years, he kept Bennett in charge of talking to the unions trying to organize the Ford Motor Company. Sorensen's memoir makes clear that Ford's purpose in putting Bennett in charge
492-475: A one-room school , Springwells Middle School. He never attended high school ; he later took a bookkeeping course at a commercial school. His father gave him a pocket watch when he was 12. At 15, Ford dismantled and reassembled the timepieces of friends and neighbors dozens of times, gaining the reputation of a watch repairman. At twenty, Ford walked four miles to their Episcopal church every Sunday. Ford said two significant events occurred in 1875 when he

After his promotion to Chief Engineer in 1893, he had enough time and money to devote attention to his experiments on gasoline engines . These experiments culminated in 1896 with the completion of a self-propelled vehicle, which he named the Ford Quadricycle . He test-drove it on June 4. After various test drives, Ford brainstormed ways to improve
738-588: A $ 5 daily wage ($ 152 in 2023), which more than doubled the rate of most of his workers. A Cleveland, Ohio , newspaper editorialized that the announcement "shot like a blinding rocket through the dark clouds of the present industrial depression". The move proved extremely profitable; instead of constant employee turnover, the best mechanics in Detroit flocked to Ford, bringing their human capital and expertise, raising productivity, and lowering training costs. Ford announced his $ 5-per-day program on January 5, 1914, raising
861-456: A 200 feet span (also termed Beose Bridge) was constructed near Sagar, India during 1828–1830 by Duncan Presgrave, Mint and Assay Master. The Clifton Suspension Bridge (designed in 1831, completed in 1864 with a 214 m central span), is similar to the Sagar bridge. It is one of the longest of the parabolic arc chain type. The current Marlow suspension bridge was designed by William Tierney Clark and
984-559: A 48-hour week, but in 1926 it was announced as five 8-hour days, giving a 40-hour week. The program apparently started with Saturday being designated a workday, before becoming a day off sometime later. On May 1, 1926, the Ford Motor Company's factory workers switched to a five-day, 40-hour workweek, with the company's office workers making the transition the following August. Ford had decided to boost productivity, as workers were expected to put more effort into their work in exchange for more leisure time. Ford also believed decent leisure time
1107-535: A Detroit-area coal dealer. They formed a partnership, Ford & Malcomson, Limited, to manufacture automobiles. Ford went to work designing an inexpensive automobile, and the duo leased a factory and contracted with a machine shop owned by John and Horace E. Dodge to supply over $ 160,000 in parts. Sales were slow, and a crisis arose when the Dodge brothers demanded payment for their first shipment. In response, Malcomson brought in another group of investors and convinced
1230-491: A bombshell with the flathead Ford V8 , the first low-price eight-cylinder engine. The flathead V8, variants of which were used in Ford vehicles for 20 years, was the result of a secret project launched in 1930 and Henry had initially considered a radical X-8 engine before agreeing to a conventional design. It gave Ford a reputation as a performance make well-suited for hot-rodding. Ford did not believe in accountants; he amassed one of
1353-492: A bridge has a tendency to collapse simply because of the gravitational forces acting on the materials of which the bridge is made. Live load refers to traffic that moves across the bridge as well as normal environmental factors such as changes in temperature, precipitation, and winds. Dynamic load refers to environmental factors that go beyond normal weather conditions, factors such as sudden gusts of wind and earthquakes. All three factors must be taken into consideration when building

#17328446735301476-468: A bridge. Silver Bridge (USA) was an eyebar chain highway bridge, built in 1928, that collapsed in late 1967, killing forty-six people. The bridge had a low-redundancy design that was difficult to inspect. The collapse inspired legislation to ensure that older bridges were regularly inspected and maintained. Following the collapse a bridge of similar design was immediately closed and eventually demolished. A second similarly-designed bridge had been built with
1599-757: A bridge. The principles of suspension used on a large scale also appear in contexts less dramatic than road or rail bridges. Light cable suspension may prove less expensive and seem more elegant for a cycle or footbridge than strong girder supports. An example of this is the Nescio Bridge in the Netherlands, and the Roebling designed 1904 Riegelsville suspension pedestrian bridge across the Delaware River in Pennsylvania. The longest pedestrian suspension bridge, which spans

"The only way things can be done today, is by private business," said Henry Ford , who backed the project. The bridge was constructed with investment from Detroit business people incorporated as the Detroit International Bridge Corporation. Much later Berkshire Hathaway acquired
1845-523: A commercial device to help their business. Sales skyrocketed—several years posted 100% gains on the previous year. In 1913, Ford introduced moving assembly belts into his plants, which enabled an enormous increase in production. Although Ford is often credited with the idea, contemporary sources indicate that the concept and development came from employees Clarence Avery , Peter E. Martin , Charles E. Sorensen , and C. Harold Wills . (See Ford Piquette Avenue Plant .) Sales passed 250,000 in 1914. By 1916, as
1968-463: A complete halt. The blockade continued into February 8. On the morning of February 8, officials declared the bridge reopened, but the blockade later resumed, pushing trips to the Blue Water Bridge between Sarnia and Port Huron . The bridge over the Detroit River had the longest suspended central span in the world when it was completed in 1929—1,850 feet (560 m). This record held until
2091-523: A consultant; Ford, in response, left the company bearing his name. With Ford gone, Leland renamed the company the Cadillac Automobile Company . Teaming up with former racing cyclist Tom Cooper , Ford also produced the 80+ horsepower racer " 999 ," which Barney Oldfield was to drive to victory in a race in October 1902. Ford received the backing of an old acquaintance, Alexander Y. Malcomson ,
2214-607: A focus on business efficiency would discourage warfare because, "If every man who manufactures an article would make the very best he can in the very best way at the very lowest possible price the world would be kept out of war, for commercialists would not have to search for outside markets which the other fellow covets." Ford admitted that munitions makers enjoyed wars, but he argued that most businesses wanted to avoid wars and instead work to manufacture and sell useful goods, hire workers, and generate steady long-term profits. Ford's British factories produced Fordson tractors to increase
2337-403: A higher margin of safety and remained in service until 1991. The Tacoma Narrows Bridge , (USA), 1940, was vulnerable to structural vibration in sustained and moderately strong winds due to its plate-girder deck structure. Wind caused a phenomenon called aeroelastic fluttering that led to its collapse only months after completion. The collapse was captured on film. There were no human deaths in
2460-500: A massive new assembly plant at River Rouge for the new Model A, which launched in 1927. In addition to its price ladder, GM also quickly established itself at the forefront of automotive styling under Harley Earl 's Arts & Color Department, another area of automobile design that Henry Ford did not entirely appreciate or understand. Ford would not have a true equivalent of the GM styling department for many years. By 1926, flagging sales of
2583-799: A means to foster employment, but Ford saw this as self-defeating because, in his view, productivity was necessary for economic prosperity to exist. He believed that productivity gains that obviated certain jobs would nevertheless stimulate the broader economy and grow new jobs elsewhere, whether within the same corporation or in others. Ford also believed that union leaders had a perverse incentive to foment perpetual socio-economic crises to maintain their power. Meanwhile, he believed that smart managers had an incentive to do right by their workers, because doing so would maximize their profits. However, Ford did acknowledge that many managers were basically too bad at managing to understand this fact. But Ford believed that eventually, if good managers such as he, could fend off

Ford was a pioneer of " welfare capitalism ", designed to improve the lot of his workers and especially to reduce the heavy turnover that had many departments hiring 300 men per year to fill 100 slots. Efficiency meant hiring and keeping the best workers. Ford astonished the world in 1914 by offering
2829-606: A negotiation strategy. At one point, Matty Moroun and his chief deputy at the Detroit International Bridge Co, Dan Stamper, were jailed for non-compliance with orders to complete the on-ramps. After years of legal battles, activism by local people against neighborhood truck traffic, and stalling by Matty Moroun, the Michigan Department of Transportation (MDOT) took over the I-75/I-96 on-ramp project and opened

Henry Ford Henry Ford (July 30, 1863 – April 7, 1947) was an American industrialist and business magnate . As the founder of the Ford Motor Company , he is credited as a pioneer in making automobiles affordable for middle-class Americans through
3075-641: A proposal by Robert Stevenson for a bridge over the River Almond near Edinburgh . Roebling's Delaware Aqueduct (begun 1847) consists of three sections supported by cables. The timber structure essentially hides the cables; and from a quick view, it is not immediately apparent that it is even a suspension bridge. The main suspension cables in older bridges were often made from a chain or linked bars, but modern bridge cables are made from multiple strands of wire. This not only adds strength but improves reliability (often called redundancy in engineering terms) because
3198-432: A quarter of the shares before selling to another investor in the company, local trucking entrepreneur Manuel Moroun . Moroun continued buying further, eventually privatizing it. In April 1930, shortly after the bridge opened, a Canadian immigration inspector jumped to his death. The bridge has been used by other suicide jumpers . After it opened, high divers considered it as a venue for a record; but after measurements of
3321-821: A second span which would be built next to the Ambassador Bridge. Michigan and Canadian authorities continued to support the Gordie Howe International Bridge proposal, as it directly connects the Canadian E.C. Row Expressway and the 2015 extension of Ontario Highway 401 (which runs concurrently as a shared highway for 2 kilometres (1.2 mi) to the future crossing as the Windsor–Essex Parkway) with I-75 and I-96 in Michigan, bypasses Windsor's surface streets and reduces congestion. A twin span adjacent to
3444-538: A sequence generally described as follows. Depending on length and size, construction may take anywhere between a year and a half (construction on the original Tacoma Narrows Bridge took only 19 months) up to as long as a decade (the Akashi-Kaikyō Bridge's construction began in May 1986 and was opened in May 1998 – a total of twelve years). Suspension bridges are typically ranked by the length of their main span. These are
3567-499: A temporary walkway. Poured sockets are used to make a high strength, permanent cable termination. They are created by inserting the suspender wire rope (at the bridge deck supports) into the narrow end of a conical cavity which is oriented in-line with the intended direction of strain. The individual wires are splayed out inside the cone or 'capel', and the cone is then filled with molten lead-antimony-tin (Pb80Sb15Sn5) solder. Most suspension bridges have open truss structures to support
3690-421: A two-cylinder four horsepower motor, with a two-and-half-inch bore and a six-inch stroke, which was connected to a countershaft by a belt and then to the rear wheel by a chain. The belt was shifted by a clutch lever to control speeds at 10 or 20 miles per hour , augmented by a throttle . Other features included 28-inch wire bicycle wheels with rubber tires , a foot brake, a 3-gallon gasoline tank, and later,
3813-493: A water jacket around the cylinders for cooling. Ford added that "in the spring of 1893 the machine was running to my partial satisfaction and giving an opportunity further to test out the design and material on the road." Between 1895 and 1896, Ford drove that machine about 1000 miles. He then started a second car in 1896, eventually building three of them in his home workshop. Ford married Clara Jane Bryant (1866–1950) on April 11, 1888, and supported himself by farming and running

3936-550: Is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges , which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges . The type covered here has cables suspended between towers , with vertical suspender cables that transfer

The first iron chain suspension bridge in the Western world was the Jacob's Creek Bridge (1801) in Westmoreland County, Pennsylvania , designed by inventor James Finley . Finley's bridge was the first to incorporate all of the necessary components of a modern suspension bridge, including a suspended deck which hung by trusses. Finley patented his design in 1808, and published it in

To cross the Detroit River, these railroads operated ferries between docks on either side. The ferries lacked the capacity to handle the shipping needs of the railroads, and there were often 700–1,000 freight cars waiting to cross

He was later hired by Westinghouse to service their steam engines. In his farm workshop, Ford built a "steam wagon or tractor" and a steam car, but thought "steam was not suitable for light vehicles," as "the boiler was dangerous." Ford also said that he "did not see

Like other suspension bridge types, this type often is constructed without the use of falsework . The suspension cables must be anchored at each end of the bridge, since any load applied to the bridge is transformed into tension in these main cables. The main cables continue beyond

Real profit-sharing was offered to employees who had worked at the company for six months or more, and, importantly, conducted their lives in a manner of which Ford's "Social Department" approved. They frowned on heavy drinking, gambling, and on what are now called deadbeat dads . The Social Department used 50 investigators and support staff to maintain employee standards; a large percentage of workers were able to qualify for this "profit-sharing". Ford's incursion into his employees' private lives

While many of the stop lights commonly cited have been removed by the expansion of Highway 401 which will connect to the downriver Howe bridge, the final approach to the Ambassador Bridge remains on overcrowded Windsor surface streets. In 2007, the privately owned bridge company

Anderson and Horace Rackham . Because of Ford's volatility, Gray
6027-593: The Ford company adopted an annual model change system similar to that recently pioneered by its competitor General Motors (and still in use by automakers today). Not until the 1930s did Ford overcome his objection to finance companies, and the Ford-owned Universal Credit Corporation became a major car-financing operation. Henry Ford still resisted many technological innovations such as hydraulic brakes and all-metal roofs, which Ford vehicles did not adopt until 1935–1936. For 1932 however, Ford dropped
6150-463: The Model T finally convinced Ford to make a new model. He pursued the project with a great deal of interest in the design of the engine, chassis, and other mechanical necessities, while leaving the body design to his son. Although Ford fancied himself an engineering genius, he had little formal training in mechanical engineering and could not even read a blueprint. A talented team of engineers performed most of

In 1915, Ford blamed "German-Jewish bankers" for instigating the war. According to biographer Steven Watts, Ford's status as a leading industrialist gave him a worldview that warfare was wasteful folly that retarded long-term economic growth. The losing side in the war typically suffered heavy damage. Small business were especially hurt, for it takes years to recuperate. He argued in many newspaper articles that

Encouraged by Edison, Ford designed and built a second vehicle, completing it in 1898. Backed by the capital of Detroit lumber baron William H. Murphy, Ford resigned from the Edison Company and founded the Detroit Automobile Company on August 5, 1899. However,

Where such a bridge spans a gap between two buildings, there is no need to construct towers, as the buildings can anchor the cables. Cable suspension may also be augmented by the inherent stiffness of a structure that has much in common with a tubular bridge . Typical suspension bridges are constructed using

Along the main cables smaller cables or rods connect to the bridge deck, which is lifted in sections. As this is done, the tension in the cables increases, as it does with the live load of traffic crossing the bridge. The tension on the main cables is transferred to the ground at the anchorages and by downwards compression on

Without changing the principle we have changed the method of payment." In addition to raising his workers' wages, Ford also introduced a new, reduced workweek in 1926. The decision was made in 1922, when Ford and Crowther described it as six 8-hour days, giving

Development of wire-cable suspension bridges dates to the temporary simple suspension bridge at Annonay built by Marc Seguin and his brothers in 1822. It spanned only 18 m. The first permanent wire cable suspension bridge was Guillaume Henri Dufour 's Saint Antoine Bridge in Geneva of 1823, with two 40 m spans. The first with cables assembled in mid-air in
8118-519: The collapse was largely caused by the construction failure of the vertical hanging clamp. It was also found that poor maintenance, fatigue in the cable hanger construction materials, material quality, and bridge loads that exceed vehicle capacity, can also have an impact on bridge collapse. In 2013 the Kutai Kartanegara Bridge rebuilt the same location and completed in 2015 with a Through arch bridge design. On 30 October 2022, Jhulto Pul ,

8733-432: The construction of a tunnel under the river with the support of their counterparts at the Great Western Railway. Construction started in 1871 and continued until ventilating equipment failed the next year; work was soon abandoned. Attention turned in 1873 to the alternative of building a railroad bridge over the river. The U.S. Army Corps of Engineers commissioned a study of a bridge over the Detroit River. Representatives of
8856-503: The country, making the Ford brand known throughout the United States. Ford also was one of the early backers of the Indianapolis 500 . In 1909, Ford submitted for patent application for his invention for a new transmission mechanism. It was awarded a patent in 1911. The Model T debuted on October 1, 1908. It had the steering wheel on the left, which every other company soon copied. The entire engine and transmission were enclosed;
8979-404: The decaying appearance of the bridge and called attention to the hazard posed by crumbling concrete from its superstructure. In response, Matt Moroun accused the city of attempting to thwart the company's efforts to rebuild or repair the structure because the Canadian government is supporting plans for a new bridge across the Detroit River downriver. Suspension bridge A suspension bridge
9102-440: The decisions of his son. Ford started another company, Henry Ford and Son, and made a show of taking himself and his best employees to the new company; the goal was to scare the remaining holdout stockholders of the Ford Motor Company to sell their stakes to him before they lost most of their value. (He was determined to have full control over strategic decisions.) The ruse worked, and Henry and Edsel purchased all remaining stock from
9225-571: The failure of a few flawed strands in the hundreds used pose very little threat of failure, whereas a single bad link or eyebar can cause failure of an entire bridge. (The failure of a single eyebar was found to be the cause of the collapse of the Silver Bridge over the Ohio River .) Another reason is that as spans increased, engineers were unable to lift larger chains into position, whereas wire strand cables can be formulated one by one in mid-air from
9348-547: The federal government, the City of Windsor and the bridge company were "ongoing". The bridge's private ownership has been controversial as the bridge carries approximately 25% of trade between Canada and the United States. Although alternate routes exist, including the nearby Detroit–Windsor Tunnel , preventing monopoly status, the route is of significant value since it passes directly through major metropolitan areas. The aforementioned tunnel prohibits certain vehicles. In 2010 and 2011,
9471-446: The four cylinders were cast in a solid block; the suspension used two semi-elliptic springs. The car was simple to drive, and easy and inexpensive to repair. It was so inexpensive at $ 825 in 1908 ($ 27,980 today), with the price falling every year, that by the 1920s, a majority of American drivers had learned to drive on the Model T. Ford created a huge publicity machine in Detroit to ensure every newspaper carried stories and ads about
9594-414: The height and currents were taken into account, they were dissuaded and abandoned the attempt. On November 14, 2000, a scaffold on the bridge collapsed, sending three men into the Detroit River and leaving four workers dangling from safety harnesses. Jamie Barker, one of the workers who fell into the water, died. An engineer, George Snowden, was disciplined by Professional Engineers Ontario for his role in
9717-432: The highway, which may be supported by suspender cables or their own trusswork . In cases where trusswork supports the spans, there will be very little arc in the outboard main cables. The earliest suspension bridges were ropes slung across a chasm, with a deck possibly at the same level or hung below the ropes such that the rope had a catenary shape. The Tibetan siddha and bridge-builder Thangtong Gyalpo originated
9840-448: The initiative to connect the Midwest to central Canada . After they created a bridge company, the project got into trouble when a Toronto financier hired to sell its securities instead embezzled the money and ran off, before ultimately committing suicide in a prison cell after conviction for murdering a drugstore clerk. The bridge boosters turned to New Yorker Joseph A. Bower,
9963-459: The later half of the 1880s, he began repairing and later constructing engines, and through the 1890s worked with a division of Edison Electric . He founded the Ford Motor Company in 1903 after prior failures in business, but success in constructing automobiles. The introduction of the Ford Model T automobile in 1908 is credited with having revolutionized both transportation and American industry. As
10086-530: The live loads. In an underspanned suspension bridge, also called under-deck cable-stayed bridge, the main cables hang entirely below the bridge deck, but are still anchored into the ground in a similar way to the conventional type. Very few bridges of this nature have been built, as the deck is inherently less stable than when suspended below the cables. Examples include the Pont des Bergues of 1834 designed by Guillaume Henri Dufour ; James Smith's Micklewood Bridge; and
10209-450: The low-end market. Although Henry Ford was against replacing the Model T, now 16 years old, Chevrolet was mounting a bold new challenge as GM's entry-level division in the company's price ladder. Ford also resisted the increasingly popular idea of payment plans for cars. With Model T sales starting to slide, Ford was forced to relent and approve work on a successor model, shutting down production for 18 months. During this time, Ford constructed
10332-506: The minimum daily pay from $ 2.34 to $ 5 for qualifying male workers. Detroit was already a high-wage city, but competitors were forced to raise wages or lose their best workers. Ford's policy proved that paying employees more would enable them to afford the cars they were producing and thus boost the local economy. He viewed the increased wages as profit-sharing linked with rewarding those who were most productive and of good character. It may have been James Couzens who convinced Ford to adopt
10455-628: The modern method was Joseph Chaley 's Grand Pont Suspendu in Fribourg , in 1834. In the United States, the first major wire-cable suspension bridge was the Wire Bridge at Fairmount in Philadelphia, Pennsylvania. Designed by Charles Ellet Jr. and completed in 1842, it had a span of 109 m. Ellet's Niagara Falls suspension bridge (1847–48) was abandoned before completion. It was used as scaffolding for John A. Roebling 's double decker railroad and carriage bridge (1855). The Otto Beit Bridge (1938–1939)
10578-399: The new product. Ford's network of local dealers made the car ubiquitous in almost every city in North America. As independent dealers, the franchises grew rich and publicized not just the Ford but also the concept of automobiling; local motor clubs sprang up to help new drivers and encourage them to explore the countryside. Ford was always eager to sell to farmers, who looked at the vehicle as
10701-472: The other investors, thus giving the family sole ownership of the company. In 1922, Ford also purchased Lincoln Motor Co. , founded by Cadillac founder Henry Leland and his son Wilfred during World War I. The Lelands briefly stayed to manage the company, but were soon expelled from it. Despite this acquisition of a premium car maker, Henry displayed relatively little enthusiasm for luxury automobiles in contrast to Edsel, who actively sought to expand Ford into
10824-440: The pacifist Rosika Schwimmer gained favor with Ford, who agreed to fund a Peace Ship to Europe, where World War I was raging. He led 170 other peace activists. Ford's Episcopalian pastor, Reverend Samuel S. Marquis, accompanied him on the mission. Marquis headed Ford's Sociology Department from 1913 to 1921. Ford talked to President Woodrow Wilson about the mission but had no government support. His group went to neutral Sweden and
10947-406: The pillars to deck-level supports, and further continue to connections with anchors in the ground. The roadway is supported by vertical suspender cables or rods, called hangers. In some circumstances, the towers may sit on a bluff or canyon edge where the road may proceed directly to the main span. Otherwise, the bridge will typically have two smaller spans, running between either pair of pillars and
11070-527: The previous owners put it on the New York Stock Exchange and shares were traded, Moroun was able to buy shares, eventually acquiring the bridge. The bridge carries 60 to 70 percent of commercial truck traffic in the region. Moroun also owned the Ammex Detroit duty-free stores at both the bridge and the tunnel. The passage across the Detroit River became an important traffic route following
11193-456: The price dropped to $ 360 for the basic touring car, sales reached 472,000. By 1918, half of all cars in the United States were Model Ts. All new cars were black; as Ford wrote in his autobiography, "Any customer can have a car painted any color that he wants so long as it is black." Until the development of the assembly line, which mandated black because of its quicker drying time, Model Ts were available in other colors, including red. The design
11316-413: The railing and the walking layer of Gyalpo's bridges used wires. The stress points that carried the screed were reinforced by the iron chains. Before the use of iron chains it is thought that Gyalpo used ropes from twisted willows or yak skins. He may have also used tightly bound cloth. The Inca used rope bridges , documented as early as 1615. It is not known when they were first made. Queshuachaca
11439-629: The ramps in September 2012 after a six-month construction period. One possible motive for the Gateway Project delays was Moroun's desire to route traffic past his lucrative duty-free store and fuel pumps, one of only two border locations to sell untaxed fuel (the other is International Falls, Minnesota ). Critics of the duty-free fuel operation objected that sixty cents from each U.S. gallon went not to paving Michigan's underfunded highways but instead directly to Matty Moroun. Operators of large trucks under
11562-472: The river, with numerous passengers delayed in transit. Warehouses in Chicago were forced to store grain that they could not ship to eastern markets and foreign goods were stored in eastern warehouses waiting shipment to the western United States. The net effect of these delays increased commodity prices in the country, and both merchants and farmers wanted a solution from the railroads. The Michigan Central proposed
11685-639: The river. This tunnel benefited the Michigan Central and Great Western railroads, but the Canada Southern Railway and other lines still preferred a bridge over the river. Plans for a bridge were revived in 1919 to commemorate the end of World War I and to honor the "youth of Canada and the United States who served in the Great War". However neither Ontario nor Michigan wanted to finance a river crossing. Michigan automakers subsequently decided to take
11808-592: The roadbed, particularly owing to the unfavorable effects of using plate girders, discovered from the Tacoma Narrows Bridge (1940) bridge collapse. In the 1960s, developments in bridge aerodynamics allowed the re-introduction of plate structures as shallow box girders , first seen on the Severn bridge , built 1961–1966. In the picture of the Yichang Bridge , note the very sharp entry edge and sloping undergirders in
11931-532: The shipping industry on the Great Lakes opposed any bridge with piers in the river as a hazard to navigation. Discussions continued for the remainder of the decade to no avail; a bridge over the Detroit River was not approved. The U.S. Congress requested a new study for a bridge in 1889, but no bridge was approved. Finally, the Michigan Central built the Detroit River Tunnel in 1909–10 to carry trains under
12054-483: The sidewalk was closed due to ongoing maintenance projects and repainting. Originally painted gloss black, the bridge underwent a five-year refurbishment between 1995 and 2000, which included stripping and repainting the bridge teal . Granite blocks, originally used on the U.S. side, were given to the Windsor Parks and Recreation Department, and now grace many of the pathways in Windsor parks. The Ambassador Bridge
12177-472: The sole owner of the Ford Motor Company, Ford became one of the wealthiest persons in the world. He was also among the pioneers of the five-day work-week . Ford believed that consumerism could help to bring about world peace . His commitment to systematically lowering costs resulted in many technical and business innovations, including a franchise system, which allowed for car dealerships throughout North America and in major cities on six continents. Ford
12300-409: The strength of duralumin . The plane was similar to Fokker 's V.VII–3m. The Trimotor first flew on June 11, 1926, and was the first successful U.S. passenger airliner, accommodating about 12 passengers in a rather uncomfortable fashion. Several variants were also used by the U.S. Army . The Smithsonian Institution has honored Ford for changing the aviation industry. 199 Trimotors were built before it
12423-401: The suspension bridge shown. This enables this type of construction to be used without the danger of vortex shedding and consequent aeroelastic effects, such as those that destroyed the original Tacoma Narrows bridge. Three kinds of forces operate on any bridge: the dead load, the live load, and the dynamic load. Dead load refers to the weight of the bridge itself. Like any other structure,
12546-510: The system that came to be known as Fordism . In 1911, he was awarded a patent for the transmission mechanism that would be used in the Ford Model T and other automobiles. Ford was born in a farmhouse in Springwells Township , Michigan , and left home at the age of 16 to find work in Detroit . It was a few years before this time that Ford first experienced automobiles, and throughout
12669-508: The ten bridges with the longest spans, followed by the length of the span and the year the bridge opened for traffic: (Chronological) Broughton Suspension Bridge (England) was an iron chain bridge built in 1826. One of Europe's first suspension bridges, it collapsed in 1831 due to mechanical resonance induced by troops marching in step. As a result of the incident, the British Army issued an order that troops should "break step" when crossing
12792-489: The towers. In cable-stayed bridges, the towers are the primary load-bearing structures that transmit the bridge loads to the ground. A cantilever approach is often used to support the bridge deck near the towers, but lengths further from them are supported by cables running directly to the towers. By design, all static horizontal forces of the cable-stayed bridge are balanced so that the supporting towers do not tend to tilt or slide and so must only resist horizontal forces from
12915-577: The upscale market. The original Lincoln Model L that the Lelands had introduced in 1920 was also kept in production, untouched for a decade until it became too outdated. It was replaced by the modernized Model K in 1931. By the mid-1920s, General Motors was rapidly rising as the leading American automobile manufacturer. GM president Alfred Sloan established the company's "price ladder" whereby GM would offer an automobile for "every purse and purpose" in contrast to Ford's lack of interest in anything outside
13038-554: The use of iron chains in his version of simple suspension bridges . In 1433, Gyalpo built eight bridges in eastern Bhutan . The last surviving chain-linked bridge of Gyalpo's was the Thangtong Gyalpo Bridge in Duksum en route to Trashi Yangtse , which was finally washed away in 2004. Gyalpo's iron chain bridges did not include a suspended-deck bridge , which is the standard on all modern suspension bridges today. Instead, both
13161-403: The use of experimenting with electricity, due to the expense of trolley wires , and "no storage battery was in sight of a weight that was practical." In 1885, Ford repaired an Otto engine , and in 1887 he built a four-cycle model with a one-inch bore and a three-inch stroke . In 1890, Ford started work on a two-cylinder engine. Ford said, "In 1892, I completed my first motor car, powered by
13284-423: The weight of the cables is small compared to the weight of the deck. One can see the shape from the constant increase of the gradient of the cable with linear (deck) distance, this increase in gradient at each connection with the deck providing a net upward support force. Combined with the relatively simple constraints placed upon the actual deck, that makes the suspension bridge much simpler to design and analyze than
13407-436: The world's largest fortunes without ever having his company audited under his administration. Without an accounting department, Ford had no way of knowing exactly how much money was being taken in and spent each month, and the company's bills and invoices were reportedly guessed at by weighing them on a scale. Not until 1956 would Ford be a publicly-traded company. Also, at Edsel's insistence, Ford launched Mercury in 1939 as
13530-549: Was 12: he received the watch, and he witnessed the operation of a Nichols and Shepard road engine, "...the first vehicle other than horse-drawn that I had ever seen". Ford was devastated when his mother died in 1876. His father expected him to take over the family farm eventually, but he despised farm work. He later wrote, "I never had any particular love for the farm—it was the mother on the farm I loved." In 1879, Ford left home to work as an apprentice machinist in Detroit, first with James F. Flower & Brothers, and later with
13653-554: Was born in County Cork , Ireland, to a family that had emigrated from Somerset , England in the 16th century. His mother, Mary Ford (née Litogot; 1839–1876), was born in Michigan as the youngest child of Belgian immigrants; her parents died when she was a child and she was adopted by neighbors, the O'Herns. Henry Ford's siblings were John Ford (1865–1927); Margaret Ford (1867–1938); Jane Ford (c. 1868–1945); William Ford (1871–1917) and Robert Ford (1873–1877). Ford finished eighth grade at
13776-643: Was built between 1829 and 1832, replacing a wooden bridge further downstream which collapsed in 1828. It is the only suspension bridge across the non-tidal Thames. The Széchenyi Chain Bridge , (designed in 1840, opened in 1849), spanning the River Danube in Budapest, was also designed by William Clark and it is a larger-scale version of Marlow Bridge. An interesting variation is Thornewill and Warham 's Ferry Bridge in Burton-on-Trent , Staffordshire (1889), where
13899-584: Was discontinued in 1933, when the Ford Airplane Division shut down because of poor sales during the Great Depression . In 1985, Ford was posthumously inducted into the National Aviation Hall of Fame for his impact on the industry. Ford opposed war, which he viewed as a terrible waste, and supported causes that opposed military intervention . Ford became highly critical of those who he felt financed war, and he tried to stop them. In 1915,
14022-413: Was elected president of the company. Ford then demonstrated a newly designed car on the ice of Lake St. Clair , driving 1 mile (1.6 km) in 39.4 seconds and setting a new land speed record at 91.3 miles per hour (146.9 kilometres per hour). Convinced by this success, race driver Barney Oldfield , who named this new Ford model " 999 " in honor of the fastest locomotive of the day, took the car around
14145-418: Was fervently promoted and defended by Ford, and production continued as late as 1927; the final total production was 15,007,034. This record stood for the next 45 years, and was achieved in 19 years from the introduction of the first Model T (1908). Henry Ford turned the presidency of Ford Motor Company over to his son Edsel Ford in December 1918. Henry retained final decision authority and sometimes reversed
14268-399: Was fueled by the prospect of lost profits from duty-free gasoline sales, which are exempt from about 60 cents per gallon in taxes even though the pump price to consumers is only a few cents lower. On May 5, 2011, a judge dismissed the case, citing a lack of reasoning for it to proceed. Moroun and his Detroit International Bridge Company contended that the new bridge would affect its proposal for
14391-629: Was good for business, giving workers additional time to purchase and consume more goods. However, charitable concerns also played a role. Ford explained, "It is high time to rid ourselves of the notion that leisure for workmen is either 'lost time' or a class privilege." Ford was adamantly against labor unions . He explained his views on unions in Chapter 18 of My Life and Work . He thought they were too heavily influenced by leaders who would end up doing more harm than good for workers despite their ostensible good motives. Most wanted to restrict productivity as
14514-414: Was granted a permit by the Michigan Department of Environmental Quality to build a new bridge across the Detroit River adjacent to the existing span. The permit expired in 2012. The U.S. Coast Guard issued the bridge company a permit in 2016 to construct the new span. As of 2021, construction cannot proceed until current bridge owner Matthew Moroun addresses a "conflict" with the bridge's permit issued for
14637-540: Was highly controversial, and he soon backed off from the most intrusive aspects. By the time he wrote his 1922 memoir, he spoke of the Social Department and the private conditions for profit-sharing in the past tense. He admitted that "paternalism has no place in the industry. Welfare work that consists in prying into employees' private concerns is out of date. Men need counsel and men need help, often special help; and all this ought to be rendered for decency's sake. But
14760-599: Was known for his pacifism during the first years of World War I , although during the war his company became a major supplier of weapons. He promoted the League of Nations . In the 1920s Ford promoted antisemitism through his newspaper The Dearborn Independent and the book The International Jew . He opposed his country's entry into World War II , and served for a time on board of the America First Committee . After his son Edsel died in 1943, Ford resumed control of
14883-629: Was signed in June 1941. About a year later, Ford told Walter Reuther, "It was one of the most sensible things Harry Bennett ever did when he got the UAW into this plant." Reuther inquired, "What do you mean?" Ford replied, "Well, you've been fighting General Motors and the Wall Street crowd. Now you're in here and we've given you a union shop and more than you got out of them. That puts you on our side, doesn't it? We can fight General Motors and Wall Street together, eh?" Like other automobile companies, Ford entered
15006-404: Was the first modern suspension bridge outside the United States built with parallel wire cables. Two towers/pillars, two suspension cables, four suspension cable anchors, multiple suspender cables, the bridge deck. The main cables of a suspension bridge will form a catenary when hanging under their own weight only. When supporting the deck, the cables will instead form a parabola , assuming
15129-472: Was to make sure no agreements were ever reached. The Ford Motor Company was the last Detroit automaker to recognize the UAW, despite pressure from the rest of the U.S. automotive industry and even the U.S. government. A sit-down strike by the UAW union in April 1941 closed the River Rouge Plant . Sorensen recounted that a distraught Henry Ford was very close to following through with a threat to break up
