The Hoover Dam is an esteemed dam that should be respected for its part in American history. The Hoover Dam is located in the north-western part of Arizona and can be reached with a little bit of a drive. From Phoenix, it would take around 4 hours of driving to get to the Hoover Dam. However, for towns located either on the north-western areas of Arizona can get to the Hoover Dam in a range of 2 hours or less. Either way, making the effort while youâre in Arizona to go and take part in Hoover Dam tours will be very educational and memorable.
Named one of the Top 10 Construction Achievements of the 20th Century, Hoover Dam continues to draw crowds 80 years after its creation. Attracting more than a million visitors a year, Hoover Dam is located in Black Canyon, just minutes outside of Las Vegas. On April 20, 1931, construction began on the Hoover Dam, the largest of its kind at the time. Despite the remote location and harsh working conditions, it was completed on March 1, 1936 in less than five years -- two years ahead of schedule -- and well under budget.
