Cost of a concrete driveway. Gary Salerno, owner of A+ Plus Concrete & Foundation Repair in Carnegie, Pennsylvania, says the average cost of a concrete driveway is $5,000 to $20,000, depending on several variables. He adds contractors who use the best materials typically charge $7 to $10 per square foot.
Typically a new driveway constructed of concrete will on average cost about 150.00 per cubic yard. A cubic yard covers 81 square feet. A driveway 15 feet wide and 50 feet long is 750 sq. ft, about 10 yards of concrete, costing about 1500.00. Compare that to the cost of bulk stone.
