Add CommentI lived in Las Vegas during the time of the bridge's construction. It was truly an amazing sight to watch it being built. Night work was spectacular! Of all the recent highway construction projects in the Nevada-Arizona region, the bridge was the best. It makes to commute to Arizona much quicker and the view of Hoover Dam is incredible. Truly a masterpiece of engineering!
