Both Robinson Rd and Wealthy St have traffic that is moving too fast. The recent changes to Robinson especially, have made the road wider and seem to encourage faster speeds (versus the portion of the road that had traffic calming in Grand Rapids).
Wealthy St has traffic that is moving too quickly and there never seems to be police presence to help discourage this.
Both of these streets would benefit from traffic calming and more crosswalks (in addition to enforcing the speed limit).
In addition, the walkability of this neighborhood is also affected by the sidewalks that are never fully cleared (Grand Rapids sidewalks are almost always in better condition).
