The map shows that SE 30th parkway is a T at SE 59th but the portion in the green to the NE of 59th is a private easement not public.  If you are heading West on SE 59th you can go left on SE 30th but not right because that is private property.  I see on an "open street map" used for mapping federal wetlands that it actually goes further than what I see here with SE 59th and SE 30th continuing a long way along private property and private easements, but don't see that here.  Thanks for you attention and , hopefully, help.
