Forbes has a list of the 100 most congested intersections in the United States. I expected at least one would be from our area, but none were. 87 of out the 100 are in the Chicago, Los Angeles or New York areas, which I guess sounds about right. But amazingly Austin has four on the list (who would have guessed that?). I used to live on 6th and Harrison in San Francisco, about three blocks from #46 on the list (7th and Bryant) and I’m amazed that intersection isn’t in the top 10: it once took me 45 minutes to get from the 101 off-ramp to my house four blocks away. From that day on, I took Caltrain to work without fail.
From here (the author there has driven through all 100).
