State Trunk Highway 172 (often called Highway 172, STH 172 or WIS 172) is a state highway in the U.S. state of Wisconsin. It is a freeway from Interstate 41 (I-41) / U.S. Highway 41 (US 41) to I-43, providing a southern bypass of Green Bay. West of I-41/US-41, it continues as a surface road—Airport Drive—past the Austin Straubel International Airport towards Highway 54.
WIS 172 begins at a junction with WIS 54 in Hobart. From here, the road heads east as a surface road known as Airport Drive. After intersecting County Highway GE at a traffic circle, the highway enters Ashwaubenon, where it passes Austin Straubel International Airport. WIS 172 meets County Highway EB near the airport before becoming a freeway. After junctions with I-41 / US 41 and WIS 32, the route crosses the Fox River and enters Allouez. In Allouez, the freeway intersects WIS 57 before crossing the East River. The route has an exit at County Highway GV (Monroe Drive) before terminating at I-43 in Bellevue.
