I believe they are still public, but you have to walk up...I forgot if they are wheelchair accessible. They better be.
Wheelchair accessible from only one side. So if you're southbound in your wheelchair and want to go to a store on the northern edge of the raised sidewalk, you can get there -- but you have to go almost a full block out of your way on a narrow sidewalk. There had to be dozens of people at least who put their heads together on this and failed to think.
