You need to consider whether it makes sense to translate it at all. Typically, an address relates locally (you need to be able to find it when you're there or the local post office needs to know where to deliver the letter) so I'm not sure why you would translate it. If it is a common word like "street" or "avenue", it would be obvious and you would use it unofficially. Otherwise, it's as if you are giving your street a new name. In that case, you can go with Riverside Drive.
