Hoover Dam is a testimony to a country's ability to construct monolithic projects in the midst of adverse conditions. Built during the Great Depression, thousands of men and their families came to Black Canyon to tame the Colorado River
. It took less than 5 years to build the largest dam of its time. Now, more than 60 years later, Hoover Dam still stands as a world-renowned structure. The dam is a National Historic Landmark and has been rated by the American Society of Civil Engineers as one of America's Seven Modern Civil Engineering Wonders.
The Bureau of Reclamation started conducting tours through the Hoover Dam and Power Plant in 1937. More than 1,000,000 visitors a year take the tour and millions more drive across the dam.
The dam is located 30 miles southeast of Las Vegas, Nevada on U.S. Highway 93 at the Nevada-Arizona border.
The dam is open from 9:00 a.m. until 5:00 p.m. The Hoover Dam Visitor Center is open every day of the year except for Thanksgiving and Christmas.
