Long Hill Road has never been great for pedestrians. Only half the road has sidewalks, and most of the sidewalks are barely wide enough for one person, never mind someone in a wheelchair. The road isn't really wide enough for a shoulder, so pedestrians, whether on the sidewalk or the side of the road, are walking only a foot or two away from traffic that often goes much faster than the posted speed limit.
As if all of that weren't hazardous enough, now there are giant gouges where the road has washed out, primarily because the road was built without adequate drainage.
This next image is a storm drain (is that what they're called?) on Oak Street, next to Long Hill. I don't know how well you can see in the photo, but it is large enough for a young child to fall in.
