Don’t know much about the east coast. I’m sure some knowledgeable FReeper will chime in.
I looked it up. Freeway meant form of access = controlled. Some parts of the planned system had turnpikes along the proposed route and were added into the system. A few other exceptions have been made over the years, mostly in heavily democrat controlled, highly taxed areas.
I noticed in Texas that the normal route is free, but special lanes charge for faster access.
