Wow, lots of left exits... I'd say that it was just designed back before we realized that left exits and entrances were taboo. Some of them just seem gratuitous, too; That would never fly these days. Seattle has major congestion problems, there's no secret about that. Remember that, even with the best designs, a road that's at three times its design capacity just isn't going to flow smoothly. The extra lanes in the middle seem to be reversible flow lanes, going one way in the morning peak and another in the evening. Can a local goon confirm?

As an aside, they have raised lane markings in Seattle, colloquially called turtles. I have no idea how they don't get ripped up by snow plows! We absolutely can't use any here because they'd last exactly one storm before ending up smashed-up on the shoulder. Does it just not snow there, or do they have some special kind of plow?
