Hoover dam bridge construction by Himanshu Patel 10799 views 1. The dam’s name was a source of controversy. Surveyors originally recommended the dam be constructed at Boulder Canyon, leading the initiative to be called the Boulder Canyon Dam Project. Even when Black Canyon later was deemed a better location for the new structure, it continued to be referred to as the Boulder Dam. However, on September 17, 1930, at a ceremony in Nevada to mark the start of construction on a railroad line to the dam site, U.S. Secretary of the Interior Ray Lyman Wilbur announced the dam would be named for his boss, President Herbert Hoover, who had been inaugurated in 1929. In 1933, Hoover was succeeded in the White House by Franklin Roosevelt, and the new secretary of the interior, Harold Ickes, no fan of Hoover, declared the structure would once again be called Boulder Dam. By that point, the name Herbert Hoover also had taken on negative associations for a number of Americans, who blamed him for the Great Depression.

  1. 7. America’s second-highest bridge now reroutes traffic from the top of the dam. Since the 1930s, U.S. Route 93 ran right along the top of the dam; however, the two-lane highway was hazardous and had grown increasingly congested over the years. In an effort to remedy these problems, construction began on a dam bypass bridge in 2005. Completed five years later, the Mike O’Callaghan-Pat Tillman Memorial Bridge measures 1,905 feet long and soars nearly 900 feet above the Colorado River, making it the longest single-span concrete arch bridge in the Western Hemisphere as well as the second-highest bridge of any type in America. The structure, which cost $114 million, is named for Donal Neil “Mike” O’Callaghan, a Korean War veteran and two-term Nevada governor during the 1970s, and Pat Tillman, who gave up a professional football career with the Arizona Cardinals to enlist in the Army in 2002; he died in Afghanistan in 2004.

  3. Throughout the late 1800s and into the early 1900s, the American Southwest was rapidly growing and expanding. Since much of the region is arid, new settlements were constantly looking for water and there were various attempts made to control the Colorado River and use it as a freshwater source for municipal uses and irrigation. In addition, flood control on the river was a major issue. As electric power transmission improved, the Colorado River was also looked at as a potential site for hydroelectric power.
  4.   The Mike O'Callaghan–Pat Tillman Memorial Bridge is an arch bridge in the United States that spans the Colorado River between the states of Arizona and Nevada. The bridge is located within the Lake Mead National Recreation Area approximately 30 miles (48 km) south-east of Las Vegas, Nevada, and carries U.S. Route 93 over the Colorado River.
  5. Finally, work on the actual dam could begin. Because engineers wanted a single mass, the design called for a series of an estimated 215 vertical columns. The columns were constructed block by block by pouring concrete into square forms varying in size from 25 to 60 feet square. Each block interlocked with the next by vertical and horizontal keyways, like a Lego set. Hoover Dam is a concrete arch-gravity dam, meaning, as explained by the Public Broadcasting Service website “Building Big,” that as tons of water in the reservoir push against the concrete in the dam, compressive forces travel along the dam’s great wall into the cliffs on both sides of the dam. Because concrete creates great internal heat while hardening, Hoover Dam’s engineers worried about expansion and then contraction of the concrete. To solve the problem they created an artificial cooling system consisting of 590 miles of pipe loops embedded in the concrete with air-cooled or refrigerated water circulating through them. Buckets of concrete, mixed at two plants onsite and transported by rail, were hoisted by one of five, 20-ton cableways strung from canyon rim to canyon rim. During the summer, as each section was poured, it was the sole task of 20 men to keep the concrete moist by spraying the surface with water. Thus was Hoover Dam built, concrete block upon concrete block, the last bucket poured on May 29, 1935. That February 1, even before the last bucket was poured, water began to back up into Lake Mead when a great steel bulkhead in one of the diversion tunnels was lowered.Today, as then, electrically operated hoists atop the intake towers raise and lower gates below, drawing water in from the reservoir. The water rushes in through headers and down huge pipes called penstocks to the powerhouse, where water flowing at the rate of 2,000 to 3,000 cubic feet per second operates the 17 main turbines that spin the generators that create electricity.

Hoover Dam, Nevada (1936) It was designed to do the impossible: stop the mighty Colorado River dead in its tracks and provide water and power for the growing cities of Southern California In addition, the Hoover Dam provides low-cost hydroelectric power for Nevada, Arizona, and California. The dam generates more than four billion kilowatt-hours of electricity per year and it is one of the largest hydropower facilities in the U.S. Revenue generated from power sold at Hoover Dam also pays for all of its operating and maintenance costs.Hoover Dam is also a major tourist destination as it is located only 30 miles (48 km) from Las Vegas and is along U.S. Highway 93. Since its construction, tourism was taken into consideration at the dam and all visitor facilities were built with the best materials available at the time. However, due to security concerns after the September 11, 2001, terrorist attacks, concerns about vehicle traffic on the dam initiated the Hoover Dam Bypass project completed in 2010. The Bypass consists of a bridge and no through traffic will be allowed across. The Hoover Dam Bypass is definitely a sight to behold. 3. Bus tours include guided tour of the Hoover Dam (plus the turbine room), and then a helicopter flyover of the bridge

The building was officially opened on May 1, 1931 when President Herbert Hoover turned the lights on with a push of a button from Washington, D.C. For 41 years between 1931 and 1972 the Empire State.. Hoover Dam is 726 feet (221 metres) high and 1,244 feet (379 metres) long at the crest. It contains 4,400,000 cubic yards (3,360,000 cubic metres) of concrete. Four reinforced-concrete intake towers located above the dam divert water from the reservoir into huge steel pipes called penstocks. The water, after falling some 500 feet (150 metres) through the pipes to a hydroelectric power plant in the base of the dam, turns 17 Francis-type vertical hydraulic turbines, which rotate a series of electric generators that have a total power capacity of 2,080 megawatts. Nearly half of the generated electric power goes to the Metropolitan Water District of Southern California, the city of Los Angeles, and other destinations in southern California; the rest goes to Nevada and Arizona. The dam, power plant, and reservoir are owned and managed by the U.S. Department of the Interior’s Bureau of Reclamation.

  7. Combined with the penstocks, a series of pipes known as the outlet system can bypass the turbines and divert water into the river channel downstream if an emergency warrants or if the penstocks need maintenance. In June 1998, a torrent of water shot from the outlet system and sent whitecaps rippling down the Colorado during testing of new jet flow gates that replaced 12 obsolete needle valves in the outlet works. The new gates increased the release capacity from about 50,000 cubic feet per second to 73,000 cubic feet per second. (One cubic foot equals about 7½ gallons.) In addition, two spillways, 27 feet below the top of the dam, stand ready to send any water reaching that high into tunnels that connect to two of the original diversion tunnels.The other two original diversion tunnels, plugged at strategic points, play a key role, as well, in funneling water to the generators in the powerhouse and to the outlet system. Water never has gone over the top of Hoover Dam, nor is it supposed to, and the spillways have only been used twice. The first time, in 1941, was a test of the system. The second time, in 1983, was during a flood.

In the ensuing years, Hoover Dam and Boulder Dam were used “interchangeably, the preference often depending on the political leanings of the speaker,” according to Michael Hiltzik, author of “Colossus: Hoover Dam and the Making of the American Century.” Finally, in April 1947, President Harry Truman approved a congressional resolution that officially confirmed the dam would carry Hoover’s name.

Deconstructing History: Hoover Dam

Examples: the Golden Gate Bridge the Grand Canyon a Russian song a Shakespearean sonnet a Freudian slip. Natural and manmade landmarks Mount Everest, the Hoover Dam When two of the tunnels were finished, excavated rock and gravel were dumped into the river to form a temporary coffer dam, which began diverting the Colorado’s flow into those tunnels on November 14, 1932. Permanent coffer dams were then built, one upstream (98 feet high and 510 feet long) and one downstream (66 feet high and 350 feet long). The “construction stiffs,” as Fortune magazine referred to the workers, now were free to attack the canyon walls. Making an average 68 cents an hour, they were lowered over the canyon rim in safety belts or bosun chairs, then used steel bars to knock down any and all loose material, and 44-pound jackhammers to drill powder holes. By the summer of 1933, so many “high scalers,” as they were known, had been killed by rock slides and falling objects that the men took to making improvised hard hats by coating their cloth hats with coal tar, which proved extremely effective.With water diverted and the river bed dry, excavation began for the dam, the powerplants that sit at its toe, and the twin set of graceful intake towers, which stand prominently on the reservoir side of the dam. Using huge power shovels, men labored in shifts, 24 hours a day, removing mud, silt, and rock to reach solid bedrock. Abutments had to be shaped properly and cuts made in the canyon walls to ensure the dam could carry the forthcoming load of more than 41 billion tons.  Category:Hoover Dam.

New bridge and bypass highway at Hoover Dam. The Mike O'Callaghan-Pat Tillman Memorial Bridge is an arch bridge in the United States that spans the Colorado River between the states of Arizona.. ..as the Hoover Dam Bypass Bridge, was the first concrete-steel composite arch bridge built in the side of the bridge, is spectacular for viewing and photographing the magnificence of the Hoover Dam.. Like Life, Travel and Places can be an exhilarating. Expect a few hiccups along the way but don't let that derail your adventure Building Hoover Dam was a monumental undertaking. Construction required 5 million barrels of cement and 45 million pounds of reinforcement steel. The mass of concrete used weighed 6.6 million tons and would pave a road stretching from San Francisco to New York City. Hoover Dam’s spillways could float a battleship, and Lake Mead, when filled to capacity, contains enough water to cover Connecticut 10 feet deep. It would take a maximum of 5,218 men (employed in any one month) a total of five years to build the dam, which actually was completed ahead of schedule. The construction contract went to a combination of six prominent contracting firms that pooled their resources and incorporated as Six Companies Inc. of San Francisco, for the express purpose of building Hoover Dam. Six Companies’ low bid of nearly $49 million, awarded on March 11, 1931, was the largest construction contract let by the U.S. government up to that time. Housing and feeding workers was a huge task, as well. The government designed and built the still thriving Boulder City, six miles from the dam site. A state-of-the-art hospital anticipated the many injuries to come (the official death toll is 96 men), while a fully stocked department store, recreation hall, laundry, and amenities from a school to a post office rounded out the town. Married men and their families lived in 758 cottages, while single men lived in one of nine dormitories. The men paid $1.60 a day for room and board at the domitories, but they received a private room, transportation to and from the construction site, and all-they-could-eat meals. Beef, veal, lamb, and pork came in 20,000-pound lots shipped from Reno. With no dairies in southern Nevada, Boulder City’s food contractor purchased a 160-acre farm at Mesquite, Nevada, where 200 cows provided fresh milk, cream, and butter. Less wholesome was the road to Vegas, where bars and brothels sprang up miles before the workers with pay in their pockets could make it to what in the 1930s was a Las Vegas of only 5,000 people. While gambling had existed illegally there for years, the town secured a legal thumbs up from the Nevada Legislature in 1931, the same year construction began on Hoover Dam. While gambling was legal, drinking was not. In Boulder City, officers seized eight stills and arrested 72 people before Prohibition was repealed in early 1933.

When you climb up to this dam which is 726.4 ft tall, you can do a simple experiment. Try to pour some water out of a bottle. The liquid won't flow down as usual, but it will fly up With the official opening of the Hoover Dam Bypass Bridge (Mike O'Callaghan - Pat Tillman Memorial Bridge) in October 2010, vehicles travelling on U.S. Highway 93 no longer cross Hoover Dam Today, Hoover Dam is used as a means of flood control on the lower Colorado River. Storage and delivery of the river's waters from Lake Mead is also an integral part of the dam's usage in that it provides reliable water for irrigation in both the U.S. and Mexico as well as municipal water uses in areas like Las Vegas, Los Angeles, and Phoenix.

2. An entire city was created for people working on the dam. In the early 1930s, Boulder City, Nevada, was constructed to house 5,000 dam project workers. Before the city was built, many jobless men and their families who’d converged on the dam site, hoping to find employment in the midst of the Great Depression, had lived in squatters’ settlements. Boulder City was situated on federally owned land and had no elected officials. The city was run by an employee of the U.S. Bureau of Reclamation (the agency responsible for the dam project), who had the authority to evict residents as he saw fit. Among the local rules, alcohol and gambling were banned. The Boulder Dam Hotel was erected to host dignitaries coming to see the dam’s construction; famous figures from Bette Davis to the future Pope Pius XII visited in the 1930s. After nearly 30 years, the federal government relinquished control of Boulder City, which was incorporated in 1960.Visit the National Park Service Travel Bureau of Reclamation's Historic Water Projects to learn more about dams and powerplants.

Erected during the Great Depression, the dam was a major endeavour that employed thousands of workers; around 100 fatalities occurred during its construction. Although legislation passed by Congress in 1931 officially named the dam for Hoover, officials in the succeeding administrations of Franklin D. Roosevelt and Harry S. Truman referred to it as Boulder Dam, its name during the planning stages before construction. In 1947 Truman signed a congressional resolution restoring the structure’s formal name to official use.

Hoover Dam created America’s largest reservoir. Formed by the damning of the Colorado River, Lake Mead, the nation’s largest reservoir, covers about 248 square miles and is capable of holding some 28.9 million acre-feet of water (an acre-foot is equivalent to about 325,000 gallons). The creation of Lake Mead (named for Elwood Mead, commissioner of the U.S. Bureau of Reclamation when the dam was being planned and built) flooded the community of St. Thomas, Nevada, and turned it into a ghost town. The last resident of the town, which was settled by Mormon pioneers in 1865, rowed away from his home in 1938. Today, the reservoir supplies water to farms, businesses and millions of people in Nevada, Arizona, California and Mexico. Lake Mead also is a popular site for boating, fishing and swimming; America’s first national recreation area was established there in 1964.After the dam was authorized, thousands of workers came to southern Nevada to work on the dam.

Hoover Dam’s power plant was the world’s largest hydroelectric station from 1939 to 1949. It has an installed capacity of 2,080 megawatts (MW) and currently generates around 4 billion kilowatt-hours (kWh) of hydroelectric power annually, for homes and business in Nevada, Arizona and California. China’s Three Gorges Dam, which started generating electricity in 2003 and became fully functional nine years later, is considered the planet’s largest hydroelectric dam, with a capacity of 22,500 megawatts. In 2014, Three Gorges broke the global record for annual hydroelectric power production, generating 98.8 billion KWh of electricity. The biggest hydropower producer in the U.S., Washington State’s Grand Coulee Dam, completed in 1941 (a third power station was added in 1974), has a capacity of 6,809 MW and generates about 21 billion kWh of electricity each year. BOULDER CITY, Nv.

The Hoover Dam Bypass Bridge was completed in 2010. It spans the Colorado River from Arizona to Nevada The bridge crosses the river approximately 1,500 feet (460 m) downstream of Hoover Dam Mike O'Callaghan – (Sept. 10, 1929 – Mar. 5, 2004) Joined the Marines at sixteen, in 1952 he lost part of his left leg in the battle of Korean War, from 1971 to 1979 he was Governor of Nevada, later he was the Executive Editor at the Las Vegas Sun newspaper.Hoover Dam was officially dedicated as Boulder Dam on September 30, 1935. President Franklin D. Roosevelt was present and most of the work on the dam (with the exception of the powerhouse) was completed at the time. Congress then renamed the dam Hoover Dam after President Herbert Hoover in 1947.As early as 1901, manmade canals diverted Colorado River water to the Imperial Valley’s fruit and vegetable fields. But the Colorado was a mighty river, gouging rock mesas as it went, including the most famous gorge of all--the Grand Canyon. The Colorado could grow angry, swelling to a torrent, flooding land for miles around, clogging irrigation canals with sediment, and washing away small earth dams. In 1905, the Colorado broke out of its banks at an irrigation canal head works and ran wild for months, sending its entire flow into the Salton Sink--creating the Salton Sea. As the Colorado destroyed homes and crops, and damaged highways and railroads, its name turned to mud, much like the landscape it destroyed.To engineers at the U.S. Bureau of Reclamation, the solution was clear: a large, multipurpose dam that not only would control floods, but harness the Colorado for irrigation and hydroelectric power. Years of debate followed as opponents questioned the economic feasibility and engineering know-how for such an enormous project. Furthermore, six of the seven states in the Colorado River drainage area (Colorado, Wyoming, Utah, New Mexico, Arizona, and Nevada) expressed fears that California would get the lion’s share of the water. Then-Secretary of Commerce Herbert Hoover stepped up as the man of the hour when he oversaw a compromise in 1922 that became the Colorado River Compact. This compact divided the seven states into the Upper and Lower Basins, established a set amount of river water to be consumed annually, and left the apportionment percentages for the states to work out among themselves.On December 21, 1928, President Calvin Coolidge signed an act authorizing the Boulder Canyon Project, so named because a study originally had recommended the Boulder Canyon of the Colorado, not the nearby Black Canyon, as the site of the dam. On July 3, 1930, then-President Herbert Hoover signed the first appropriation bill. It was during dedication ceremonies on September 17, 1930, that Secretary of the Interior Ray L. Wilbur, while driving a silver spike for the railroad spur that would run to the construction site, announced that the name of the colossal structure was to be Hoover Dam. However, the soon-to-be-elected Democratic administration of Franklin Roosevelt continued to use the name Boulder Dam. It wasn’t until April 30, 1947, that a resolution of Congress made Hoover Dam the official name.

A four-year-long legal spat over Hoover Dam Bridge project's collapsed cableways has come to a close with a private settlement stemming from an April 20 arbitration ruling Once the Colorado River was diverted, two cofferdams were constructed to prevent flooding in the area where men would be building the dam. Once completed, excavation for the foundation of Hoover Dam and the installation of columns for the arch structure of the dam began. The first concrete for Hoover Dam was then poured on June 6, 1933 in a series of sections so that it would be allowed to dry and cure properly (if it had been poured all at once, heating and cooling during day and night would have caused the concrete to cure unevenly and take 125 years to cool completely). This process took until May 29, 1935, to complete and it used 3.25 million cubic yards (2.48 million m3) of concrete. Hoover Dam is a concrete gravity-arch dam in the Black Canyon of the Colorado River, on the border between Arizona and Nevada. The dam, located 48 kilometers (30 miles) southeast of Las Vegas, is named after Herbert Hoover, who played an instrumental role in its construction Vacuum cleaners from Hoover featuring the best new and reconditioned models, including powerful upright Genuine Hoover parts, filters, and vacuum cleaner accessories shipped direct to you The Hoover Dam is one of the greatest marvels of architecture in the modern era.
