I'm on the side of moving I90 south, though with discussion of turning 2 into a boulevard downtown, and 20 reducing speed as it enters Edgewater, why not just make this entire stretch of highway to at least MLK a boulevard? Give the midtown neighborhoods of Cleveland the same access to the lakefront that that the Westside has.
Situated between the downtown business district and University Circle employment centers the midtown neighborhoods should be much more vibrant but they're cutoff from the lake and downtown by 90.
