The Durango Casino & Resort in Southwest Las Vegas will open on Nov. 20, according to Red Rock Resorts. Recently, the operator tested the venue's external lights and signs, fueling rumors that the opening date was approaching faster than anticipated. The location of Durango Casino & Resort in one of the few Las Vegas neighborhoods without a high concentration of gaming establishments is one of the reasons Red Rock thinks it will be successful. The lighting for Durango's marquee will be unveiled tonight.
