Business Loop I-75 - Saginaw

Established in 1960 (Bessert, 2026) and decommissioned in October 1971, the Saginaw business loop for I-75 followed M-46 (Remington Street west / Holland Avenue east) from Exit 149 to Genesee Avenue, the former alignment of U.S. 23 Business north.

U.S. 23 Business traveled north along Genesee Avenue to a one way couplet with Janes Avenue east through Downtown Saginaw. M-13/81 joined U.S. 23 Business north along Washington Avenue to Veterans Memorial Parkway. U.S. 23 Business/M-13 returned Business Loop I-75 to I-75 via Veterans Memorial Parkway and Exit 153. This routing is shown on the 1969 R.R. Donnelley & Sons Company Michigan map base.
