Canceled freeway plans roughly equivalent to the 1967 Puget Sound Council of Governments (PSCOG) adopted 1990 transportation plan of freeways and expressways. A few roads are thrown in from the 1963/1967 King County streets and highways plans, and the 1974 version of the PSCOG plan. Also marked are a few segments not recognized by Google Maps as controlled-access facilities.Alignments are approximate, although the 1967 King County plan provided detailed street-level plans. It's hard to tell which side of the road they went on (or which road they replaced).Where possible, interchange locations are shown with pins. For proposed roads without them, I'm not going to guess.
