Crushed limestone can cost $115 per cubic yard or $143 per ton if bought in small quantities. Large-volume orders can lower the price to $65 per ton or $30 per cubic yard. One must also recognize the style and size differences of crushed limestone. The more upscale the limestone, the higher the price per square foot.
