The state funded I-43 reconstruction in the most recent biennium budget. As part of that, the Mequon interchanges would be reconstructed, at least according to the most recent plans, and an interchange would be added at Highland Road. Of course, adding a project to a budget and actually completing it are two different thngs and, in all probability, changes will be made; however, it is never too early to start planning.
Many people express concerns that, from what they hear, an interchange could not fit at Highland Road because of the railroad tracks and existing uses. Here is a depiction of the interchange prepared by Wisconsin Department of Transportation engineers:
Awesome news! Can’t wait for the interchange at Highland. Very excited to shave a few minutes off my commute! Thanks for sharing.
