There are so many variables. Can you give us a little more information about size, what is there now, slope, etc?
Typically less now then asphalt in many areas. But as Steve said, need more information. Concrete cost anywhere from $75 to $150 per cubic yard, depending upon type, strength, how long the pour is going to take, then do not forget about labor, forms and prep.
It is expensive. LOL
Julie H, do you have an existing driveway or do you just want a concrete driveway?
in lawrenceville, expect $4.50 - $ 5.00 per sf for removal & replacement
You should be able to call someone near you for an estimate. You will need to know if you have something like Tarmac that will have to be removed, the length and width of the driveway. They may come out and measure and look for,themselves what the job will entail. You want a licensed contractor to do it so,the drain off will be in the right direction, etc.
Why would you want to?
My current driveway is about a car and a half long and 2 cars wide. I was quoted $3,000 to replace it.
