400728 08: Trucks travel along Interstate 15 February 7, 2002 north of Las Vegas, NV. Interstate 15 is a primary proposed route for trucking radioactive waste from across the nation to the proposed nuclear waste dump site of Yucca Mountain, located approximately 90 miles north of Las Vegas. Although the route would skirt around downtown Las Vegas, many residents dislike the idea of shipping 70,000 tons of nuclear waste over nearby highways and railroads. In January, the U.S. Department of Energy endorsed the Yucca Mountain plan. U.S. President George W. Bush could annouce his support as early as this week.
