Downtown Las Vegas developer Derek Stevens is planning a 777-room hotel and casino along the Fremont Street Experience, the first bottom-up resort construction project in years for the downtown area. The downtown block was leveled last year — the Las Vegas Club and Mermaids casinos and Glitter Gulch strip club were razed to make way for the new hotel-casino. The development would transform the west end of Fremont Street, Las Vegas Mayor Carolyn Goodman said. Plans call for the hotel-casino to sit at the block bounded by Fremont Street, Main Street and Ogden Avenue, with a pedestrian bridge over Main Street connecting it with an above-ground parking garage.
