If your property has be "burden" of an easement over it, the owner of the parcel of land that has the benefit of the easement over yours can place a driveway over your parcel in the area stated in the easement even if he has access futher down on his parcel to get to it.I suggest that in order for you to get further clarity concerning your question that you consult with a real estate attorney. Potentially certain zoning requirements may prevent the installation of the desired driveway due to the fact that the easement's width as stated in your deed might not be presently wide enough under current code.Good luck.
