That is indeed the road. Just follow the road that you came in on straight up the hill until Hamilton Avenue and you are on the way. Therefore, your road is to the right (away from the bridge) as you face Rose Island. The road up the hill behind you is Narrgansett Avenue, and a short way up the hill at 17 Narrgansett Avenue is Jamestown Design, which is the local Harbour Lights dealer and is full of other neat stuff too.
