“see the crazy light show!”
Grand Coulee Dam is truly magnificent to behold. 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.
