Grand Coulee Dam

Built from 1933 to 1975, it is 550 feet tall, from the 500 foot wide polished granite base, to the 30 foot wide crest which supports a paved two lane road. When you include the third power house, Grand Coulee Dam is almost 1 mile long. Did you know there is enough concrete in the Grand Coulee Dam to build a 60 foot wide highway four inches thick, from Los Angeles to New York City! ~ That is a 4 lane Highway 3,000 miles long.
