Zzyzx pronounced as /ˈzaɪzɨks/, was also known as Soda Springs, a settlement in San Bernardino County. The road is a 4.5 mile long which runs from the I-15 generally to the south of the settlement where the nearest town is Baker, CA and is 100 miles northeast of Las Vegas, which is the nearest major city. And in the lexicography it is alphabetically the last place name, at least in English alphabetical order.
A little history: in my researches (wiki), it was a man named Curtis Springer who gave the name, claiming to be the last word in English language; he then established Zzyzx Mineral Springs & Health Spa in the area in 1944, where Soda Springs is a natural spring and his spa catered to the senior citizens. Also he used the springs to bottle the water and provide drinks to the travelers. Springer was then arrested in 1974 for misuse of the federal land. And it is now being managed by the California State University for their Desert Studies Center.
