This article in the Courant. comes as no surprise. But cause can be tricky. (And the slow load is a metaphor for more of the same.)
I’d suggest that a lot of the traffic issues in Hartford have to do with the issue of work, geographical scale, road type, and a whole mess of other potentials.
Much more to learn here.
Not to mention the complete JERKS that we call drivers. I would attribute a lot of the blame to the drivers, not the setting of it all. Even driving through Hartford on a Sunday morning can be downright painful.
Connecticut has its more than fair share of overly self-assured human beings.
