Plans are up at both of the links in the previous post.
The interchange at County Road C57 will be a standard diamond that will require relocation of the railroad tracks parallel to the Avenue of the Saints. Per the current five-year plan, it's expected to open by the end of 2016.
The plan for the Waverly-to-Janesville stretch is to straighten the curve near 260th Street and build an interchange there. There are two alternatives for the interchange design.
In both cases, combined with the opening of the interchange at County Road C50 last year, the eventual goal is to eliminate all intersections between Waverly and Cedar Falls.
