This belongs in the Milwaukee Freeways discussion, not the statewide garbage bin.
1,000 Friends of Wisconsin, a land use advocacy group, released their thoughts on replacing I-794 in Milwaukee with a surface boulevard. "Rethink 794."

Trying to shunt this line of discussion to this thread, where it fits better.
The site is worth clicking around on because they've got some interesting historic low-angle aerial photography of different freeway stuff around downtown. I don't think I've seen an image of the r/w cleared through to the bluff above the lake for the Park East before, for example.

And they totally cite Chris Bessert's Wisconsin Highways page in their history section about 794.
I do have to chuckle at this rendering of the Lake Interchange area stuffed to the brim with new skyscrapers:

I don't think there is that much demand for downtown real estate to build 7 new skyscrapers, including a new tallest building in the city, it would seem. Who's gonna live/work there? More high end second condos for millionaires and empty office space because everyone works from home? Let's be realistic. It will mostly be 4-10 story mixed use structures with one or two more generic condo towers.
