I-285 northwest of Atlanta.
That spot west of Chicago where I-90 comes together with 94 and 294 or something like that.
I-66 between DC and Falls Church. It was awful in the late ‘80s. I couldn’t imagine it now.
New Jersey Turnpike near the George Washington Bridge
Before I retired, I commuted everyday to Chicago from the suburbs in Downers Grove, to get to work at UIC. I would take either I-55 (Stevenson Expressway) or I-94 (Eisenhower Expressway). Both sucked, and as I lived in the Western suburbs, I would have the setting sun poking me in the eye on the way home everyday the sun was out. Did that for years; the traffic was usually horrendous, and on a snowy day, it could take me up to 2 hours or more to get home. So glad I am now retired and only have to “deal” with it when watching the poor saps on the evening news traffic reports.
