Yeah, it would make sense to want to exit if one had traveled over the Hoan Bridge, but those drivers have Michigan Street, Milwaukee Street, and 35th Street as options. Based on looking at a map, the ramp you mention actually brings traffic from both 43 (from the north) and 94 (from the south). That's a heck of a lot of traffic, probably much more than would be coming from 794. Still, 794 is a wide road, and narrowing it down to one lane is going to cause a bottleneck. The ideal solution probably would have been to make the 94 & 43 ramp merge with the East-West Freeway west of 25th Street. That would have made 25th Street physically inaccessible from 794. I see where the space problem comes into play, though. It may have been that Clybourn would have needed to cease being a through street for that to happen. That would suck.
