Thanks, again, to Ron Edge for another aerial, this one marked with the line or path of the then planned I-5 Freeway bridge over the Portage between Lake Union (proper) and Portage Bay. Can you – by now – find the underpass on 6th NE, the underpass on Campus Parkway, the Applied Physics Laboratory, and the odd intersection of 7th Ave. NE and NE 40th Street?
