There is a meeting next week to “discuss the conceptual alignments” of a bypass of IA 92 around Oskaloosa. The study area encompasses a wide space, since this is literally the first step in the process. Any construction likely wouldn’t happen for a decade.
Very preliminary looks at a west-side bypass of Oskaloosa for US 63 have been bandied about as well. Both plans would use the IA 163 extension built in 1997. It would be possible to remake the south interchange to accommodate all directions of traffic and IA 92 to go east and northeast from there.
UPDATE: A more detailed proposal is online now with multiple options. The 63/163 interchange would be turned into a folded diamond. A new interchange could be built either south of that interchange with a waaaay out-of-the way bypass for 92, or northwest of that interchange on a straight-then-diagonal alignment around the south and southeast sides of Oskaloosa.
