Google maps are a great place to find exact distance. Are you talking about The Cleveland Clinic or all of the Cleveland Clinics? There are several if so. Metro, UH for example. Old Brooklyn is approximately 25 minutes or so to The Cleveland Clinic depending on the time of day of course. Metro would be much closer. Not sure which hospital you're referring to, but Google or Yahoo maps can give you the exact route, mileage, distance, etc. if you need an exact distance.
