A high-impact rollover crash Thursday afternoon in Pahrump sends the driver to a Las Vegas trauma center and shuts down the roundabout at State Route 372 and Blagg Road. Nevada Highway Patrol is investigating. As you may have noticed in the video, the impact of the crash dislodged a large boulder in the center of the roundabout, knocking it into the roadway. A witness tells News 25 he saw the crash happen. He says the SUV became airborne after impact, and came to rest up against the front bumper of his pickup when it landed. That man was not hurt.
