The Interstate turns eastward at the Hale Interchange in Hales Corners. US 45 turns westbound at that point to follow I-43/Rock Freeway south, and I-43 north follows I-894 to the east. The highway becomes the Airport Freeway and reenters Greenfield after the Hale Interchange. Generally, this section is referred to as I-894 eastbound (westbound), as I-43 was not added until the late 1980s. Westbound I-894 exits to WIS 24 (Forest Home Avenue) after the junction, though the eastbound highway only exits to a nearby local street. I-894 has two more exits after this and meets WIS 36 (Loomis Road) before reentering Milwaukee. It meets WIS 241 (South 27th Street) at exit 9 before terminating at the Mitchell Interchange with I-94, I-43 and US 41; I-43 continues northbound concurrent with I-94.
