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.
Paving a typical two-car concrete driveway of 16 feet wide and 38 feet long (610 sq. ft.) without curves or slopes costs $3,040. Therefore, the average cost per square foot amounts to $4.99, although it can be higher if excavation is needed. Concrete Driveway (610 sq.ft.) The driveway is a 4-inch thick concrete slab 2 with reinforcing wire mesh. The required 7.7 cubic yards (including 4% loss) of prepared concrete is delivered by truck. The Total Cost includes the five-man crew that will be a total of 42 man-hours on the job, or a full day for the crew.
