Iowa Highway 141 is a major east–west highway in the western and central portions of the state. It is the most direct link between Sioux City and Des Moines. It also serves as a freeway link between Des Moines and the outlying communities of Perry, Granger, and Grimes. Iowa 141's western terminus is near Sloan at its junction with Interstate 29. Its eastern terminus is via an interchange with Interstates 35 and 80 on the northwestern corner of the Des Moines suburb of Urbandale.
Iowa Highway 141 begins at Interstate 29 just west of Sloan. It goes east through Sloan and Hornick before meeting Iowa Highway 31 in Smithland. It then turns southeast and at Mapleton meets Iowa Highway 175, with which it forms a wrong-way concurrency, as eastbound Iowa 141 goes the same direction as westbound Iowa 175. They separate and Iowa 141 continues southeast before going south into Ute, where it meets Iowa Highway 183. At Ute, it turns east and passes through Charter Oak before meeting U.S. 59 northwest of Denison. While in Denison, it meets Iowa Highway 39 and has another wrong-way concurrency with westbound U.S. 30. South of Denison, U.S. 59 and Iowa 141 separate.
