Holly, a Lubbock native, died at the age of 22 in a 1959 plane crash.
Maria Elena Holly tells the Lubbock Avalanche-Journal that she can foresee families celebrating birthdays and weddings the plaza.
Travis Holley, the late Buddy Holly's older brother, says, "I think this is absolutely beautiful. I think the city has gone above and beyond."
Randy Truesdell, director of the city's parks and recreation department, says the plaza includes drought-tolerant landscaping and a lighting design that makes the Holly statue visible from Interstate 27.
