One of Las Vegas’ earliest traffic innovations has seen its last day. After three decades of shuttling riders between the Mirage and Treasure Island, the short — 1,000-foot, 90-second — free tram has discontinued service. The tram began running in 1993 when Treasure Island opened; at the time, both it and the Mirage were owned by the same company. It survived ownership changes at both casinos, but the writing was on the wall came when Hard Rock took over operations at the Mirage and announced the resort’s closure to facilitate the rebranding.
