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.
I've installed many concrete driveways and have one myself. Most of the concrete driveways that I've installed cost about $6.00 dollars per square foot. The concrete driveway we did in the picture above was 1,500 square feet and cost $9000.00 dollars. 1. 4 - 5 inch thick plain gray concrete (4000 psi)
