Shek has a cool map at his place of the Twin Cities from before the interstates were built:
Looking closer, you can see where the projected routes for I-94 and I-35W were dashed into the map:
A close look by my house shows 47th Avenue S running through to 32nd. I don’t know the history of that well, but I believe Minnehaha Academy managed to acquire that street for additional parking and to connect their soccer field to their campus.
Take a look at the lower-left corner of the first map. No 494 and no Eden Prairie. The Crosstown stopped around Edina.
If you click on the pictures, you can see larger views on Flickr. But if you really want to see the map, talk to Shek.
