They are not freeways, they are limited access expressways. For a road to be a freeway it needs to be completely grade separate through interchanges, and also come with higher speed limits.
Anyone who is against the Golden Ears Bridge IMO simply decides to hate upon any road expansion without accessing it case by case to simply meet their pre determined agenda. The same way with someone who hates any transit project just because.
Also, the NFPR is largely already in place, it is simply a collection of existing roads that will be given better connectivity with each other.
