Make a U-TURN and go back to U.S. 41.
WI 172 is a freeway for about one mile west of U.S. 41. It then ends at a signalized intersection with Babcock Rd. It is the intersection with the most accidents in Brown County. There are ongoing plans to put an interchange there or at the next crossroad, Packerland Ave. But there is much disagreement between the progress faction and the business sector. So not much will happen in the next few years. WI 172 is a 4-lane road for another mile or so, to just past Austin Straubel International airport.
