South Lake Tahoe:
South Lake Tahoe is the most populous city in El Dorado County, California, United States, in the Sierra Nevada Mountains. The east end of the city, on the California-Nevada state line, is mainly geared towards tourism, with T-shirt shops, restaurants, hotels, and Heavenly Mountain Resort with the Nevada casinos just across the state line in Stateline, Nevada. The city extends about five miles (8 km) west-southwest along U.S. Route 50, also known as Lake Tahoe Blvd. The western end of town is mainly residential, and clusters around "The Y" (new intersection October 2008), the X-shaped intersection of US 50, State Route 89, and the continuation of Lake Tahoe Boulevard after it loses its Federal highway designation.
