Travelers have flocked here for decades to see picturesque views of Lake Mead and the Colorado River, and today, the dam receives more than 1 million annual visitors.
The dam is a popular day trip destination from Las Vegas. Visitors can tour the power plant, learn how the dam generates and distributes electricity, and see stunning views of the surrounding riverways, canyons, and valleys.
Tour options cover a wide range of interests—visit on a comedy bus, cruise in a Hummer, or even pair the trip with a stop at an outdoor shooting range.
For an epic adventure, take in the sites on a helicopter tour or opt for a mountain biking excursion along the waterway. Bring sun protection, comfortable shoes, and plenty of water.
The Hoover Dam Visitors Center and power plant tour are wheelchair accessible, but the dam tour is not accessible. Complimentary parking is available for wheelchair users.
The Hoover Dam is located 30 miles 48 kilometers southeast of Las Vegas, or 45 minutes by road, near the Arizona—Nevada border. The nearest airport is McCarran International Airport in Las Vegas.
Parking can be found near the visitors center. Because of the stifling desert heat in summer, spring and fall are the best times to visit the Hoover Dam.
Expect long lines and heavy traffic on summer weekends; opt for an early morning visit to avoid crowds. A Hoover Dam tour features much more than just a foot meter wall.
Explore tunnels that were bored directly into the mountainside, hear the harrowing tales of workers who carved them out by hand, and tour the power plant.

The dam is used for flood and silt control, hydroelectric power , agricultural irrigation , and domestic water supply.
It is also a major sightseeing destination, with some seven million visitors a year, almost one million of whom go on tours through the dam.
Hoover Dam is feet metres high and 1, feet metres long at the crest. It contains 4,, cubic yards 3,, cubic metres of concrete. Four reinforced-concrete intake towers located above the dam divert water from the reservoir into huge steel pipes called penstocks.
Unter Präsident Harry S. Truman wurde dieser Schritt abermals rückgängig gemacht: Am April ordnete Truman an, dass die Talsperre wieder den Namen des Präsidenten trug, unter dessen Amtszeit das Bauprojekt gestartet wurde.
Im Deutschen finden sich als Übersetzung auch die Bezeichnungen Hoover-Damm , Hoover-Staudamm und Hoover-Talsperre sowie, mit Rücksicht auf die Bauweise, Hoover-Staumauer.
Die elektrische Leistung der von den 17 Turbinen angetriebenen Generatoren beträgt etwa 2. Hochspannungsmasten mussten als schiefe Konstruktion am Rand der senkrecht abfallenden Schlucht gebaut werden.

Der aufgestaute See weist eine Fläche von The Colorado River Board found the project feasible, but warned that should the dam fail, every downstream Colorado River community would be destroyed, and that the river might change course and empty into the Salton Sea.
The Board cautioned: "To avoid such possibilities, the proposed dam should be constructed on conservative if not ultra-conservative lines.
On December 21, , President Coolidge signed the bill authorizing the dam. This occurred on March 6, , with Utah's ratification; Arizona did not approve it until Even before Congress approved the Boulder Canyon Project, the Bureau of Reclamation was considering what kind of dam should be used.
Officials eventually decided on a massive concrete arch-gravity dam , the design of which was overseen by the Bureau's chief design engineer John L.
The monolithic dam would be thick at the bottom and thin near the top, and would present a convex face towards the water above the dam.
The curving arch of the dam would transmit the water's force into the abutments, in this case the rock walls of the canyon.
On January 10, , the Bureau made the bid documents available to interested parties, at five dollars a copy. The government was to provide the materials; but the contractor was to prepare the site and build the dam.
The contractor had seven years to build the dam, or penalties would ensue. The Wattis Brothers , heads of the Utah Construction Company , were interested in bidding on the project, but lacked the money for the performance bond.
They lacked sufficient resources even in combination with their longtime partners, Morrison-Knudsen , which employed the nation's leading dam builder, Frank Crowe.
They formed a joint venture to bid for the project with Pacific Bridge Company of Portland, Oregon ; Henry J.
Shea Company of Portland, Oregon. The name was descriptive and was an inside joke among the San Franciscans in the bid, where "Six Companies" was also a Chinese benevolent association in the city.
The city of Las Vegas had lobbied hard to be the headquarters for the dam construction, closing its many speakeasies when the decision maker, Secretary of the Interior Ray Wilbur , came to town.
Instead, Wilbur announced in early that a model city was to be built in the desert near the dam site. This town became known as Boulder City, Nevada.
Construction of a rail line joining Las Vegas and the dam site began in September Soon after the dam was authorized, increasing numbers of unemployed people converged on southern Nevada.
Las Vegas, then a small city of some 5,, saw between 10, and 20, unemployed descend on it. Known as McKeeversville, the camp was home to men hoping for work on the project, together with their families.
As part of the contract, Six Companies, Inc. The original timetable called for Boulder City to be built before the dam project began, but President Hoover ordered work on the dam to begin in March rather than in October.
Workers with families were left to provide their own accommodations until Boulder City could be completed,  and many lived in Ragtown. The Industrial Workers of the World IWW or "Wobblies" , though much-reduced from their heyday as militant labor organizers in the early years of the century, hoped to unionize the Six Companies workers by capitalizing on their discontent.
They sent eleven organizers,  several of whom were arrested by Las Vegas police. Although the workers sent the organizers away, not wanting to be associated with the "Wobblies", they formed a committee to represent them with the company.
The committee drew up a list of demands that evening and presented them to Crowe the following morning. He was noncommittal.
The workers hoped that Crowe, the general superintendent of the job, would be sympathetic; instead, he gave a scathing interview to a newspaper, describing the workers as "malcontents".
On the morning of the 9th, Crowe met with the committee and told them that management refused their demands, was stopping all work, and was laying off the entire work force, except for a few office workers and carpenters.
Concerned that a violent confrontation was imminent, most workers took their paychecks and left for Las Vegas to await developments.
On August 13, the company began hiring workers again, and two days later, the strike was called off. Living conditions began to improve as the first residents moved into Boulder City in late A second labor action took place in July , as construction on the dam wound down.
When a Six Companies manager altered working times to force workers to take lunch on their own time, workers responded with a strike.
The company agreed to ask the Federal government to supplement the pay, but no money was forthcoming from Washington. The strike ended. Before the dam could be built, the Colorado River needed to be diverted away from the construction site.
To accomplish this, four diversion tunnels were driven through the canyon walls, two on the Nevada side and two on the Arizona side. To meet the deadline, Six Companies had to complete work by early , since only in late fall and winter was the water level in the river low enough to safely divert.
Tunneling began at the lower portals of the Nevada tunnels in May Shortly afterward, work began on two similar tunnels in the Arizona canyon wall.
In March , work began on lining the tunnels with concrete. First the base, or invert, was poured. Gantry cranes , running on rails through the entire length of each tunnel were used to place the concrete.
The sidewalls were poured next. Movable sections of steel forms were used for the sidewalls. Finally, using pneumatic guns, the overheads were filled in.
This was done by exploding a temporary cofferdam protecting the Arizona tunnels while at the same time dumping rubble into the river until its natural course was blocked.
Forming the Massive Concrete Blocks that made up the Hoover Dam To build the dam, enormous seven foot deep and seven foot wide buckets poured concrete into square and rectangular forms ranging from 25 by 25 feet to 25 by 60 feet.
Depending on the square-footage of the block needed, the concrete level would rise two to six inches after each pour, making it rather difficult to lose a worker in a small increase in depth.
Falling into the concrete might become an issue, but the workers could easily be extracted before the concrete hardened. Decaying bodies are an architectural issue If a body did make its way into the Hoover Dam, the point of burial would quickly become a weakness in the structural integrity of that particular concrete block.
A human body is less structurally sound than the same volume of concrete. 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.
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.
Highway 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, , terrorist attacks, concerns about vehicle traffic on the dam initiated the Hoover Dam Bypass project completed in The Bypass consists of a bridge and no through traffic will be allowed across.
