Sunday Movie: I-90 in the 1970s
by Mike Orr from Seattle Transit Blog on (#6WEAZ)

Driving from Mercer Island to downtown Seattle in 1973. (Mark Tyrrell)
Seattle Now & Then article on the video.
There's one mistake in both the video and the article. US Highway 10 had been renamed to I-90 earlier, even though the road wasn't renovated until the late 80s. I moved to Seattle a year before the film and it was I-90 then. I first heard about Highway 10 until decades later when I saw it on a 1940s map.
In any case, this is the corridor East Link will soon be running in.
This is an open thread.
