@1 The first Lake Washington Floating Bridge was there from 7/1/1940 until 11/25/1990. It opened during three days of excitement in the Puget Sound area when these three projects were dedicated, one after the other. I wonder what 4th of July was like that year?
July 1, 1st Tacoma Narrows Bridge (failed November 7, 1940)
July 2, 1st Lake Washington Floating Bridge
July 3, McChord (consolidated into Joint Base Lewis-McChord February 1, 2010)
@5, not Maggie but Seattle Mayor Gordon S. Clinton, I think. See his photo in the 1963 Opening Day program
@11 it was the 252 for me
