Business Loop I-75 - Monroe

A Michigan Department of Transportation (MDOT) program spreadsheet in 2000 highlighted a number of research studies for projects across the state. Included was 1.80 miles of New Business Route Research for a business route along a combination of LaPlaisance Road, Dunbar Road and M-125 (Dixie Highway) at the city of Monroe (Bessert, 2000).

This alignment was never posted as Business Loop or Spur I-75, but is a part of an Emergency Detour route for the freeway.
