A total of three business routes of U.S. Route 41 exist in Wisconsin. Additionally, there were four business routes that have since been disestablished. Business routes typically run through cities, after a highway was realigned. None are official state highways according to the Wisconsin Department of Transportation (WisDOT) and are thus locally maintained, with the exception of the route through De Pere and Ashwaubenon.
Business Highway 41 in De Pere follows the old alignment of US 41. It is only two thirds of a mile long, extending until Ashwaubenon.[3] This route was designated and is maintained by the WisDOT.

Business U.S. Highway 41 (Bus. US 41) was a business loop in Green Bay. It was formed in 1969, using the former route of US 41 when an expressway bypass of Green Bay was completed. The route was temporarily designated as Wisconsin Highway 119 from 1968 to 1969.[8][9][10] In 1975, a freeway bypass of the Ashwaubenon–De Pere area was completed, and Business 41 was extended on the former route of US 41.[11][12] In 1998, most of the route was retired, except for a freeway spur into Ashwaubenon–De Pere.[13][1]
