McCarran needs some relief, and soon. Even building Terminal 3 at McCarran (moving Russell road to do so) is a short-term fix. There has been talk of high-speed rail service from Los Angeles to Ivanpah, but that is stalled (or dead) due to environmental concerns. Environmentalists are also fighting Ivanpah, but that is a battle I think they'll lose. I suspect MGM/Mirage has huge development plans for the property surrounding the new airport
