Johnson, 94, was to have a private burial after a 22-hour public viewing of her coffin which drew thousands Friday to the Lyndon Baines Johnson Library and Museum at the University of Texas.
Admirers filed past her coffin in the same place where her husband lay in state in 1973. Her daughters, Luci Baines Johnson Turpin and Lynda Robb, were on hand to thank those who came to pay their respects, The Dallas Morning News reported Saturday.
"If there was ever royalty in Texas, Lady Bird embodied it," said Susan Moeller, 45, of Austin, who wore a blue skirt in tribute to Johnson's beloved bluebonnet flowers.
Johnson is to be buried at the family ranch near Stonewall.
