Pardon the bump, but here's a question I've had about the Beltline: has there been any talk about bringing it east of I-39/90 and having it swing north to meet I-94 east of the city? Presumably this "East Beltline Extension" would have an exit with Highway N south of Cottage Grove, as well as Highway BB to the east of that town, but where would it junction with I-94? I'm guessing either it would tie into the existing Highway 73 exit (near Deerfield) in some fashion, or a new interchange would be built a little to the west or east of it.
Anyway, this is just speculation on my part, and as far as I know, there are no official proposals for such a road from WisDOT. What are your thoughts?
