Interstate 475 is the name of three distinct interstate highway bypass routes of Interstate 75 in the United States: in Georgia, Ohio, and Michigan.
There is also a proposal to build an I-475 in Knoxville. The project was approved by the Tennessee Department of Transportation in 2003, but it may be years before construction begins.
Georgia
The 15.83 mile Interstate 475 (also designated as Georgia State Route 408) in Georgia begins at Interstate 75 and bypasses Macon, Georgia. This is the preferred route to I-75, as the parent interstate enters downtown Macon and reduces to four lanes (two in either direction), and has a 55 MPH (88km/h) speed limit.
Interstate 475/Georgia State Route 408 Exit Numbers and Interchanges

Ohio
The 20.37 mile Interstate 475 in Ohio bypasses Toledo, Ohio to the west of the city. The southern teminus is I-74 near Perrysburg. The northern terminus is I-75 near downtown Toledo. From the southern terminus to exit 14, I-475 is co-signed with US 23.
Although I-475 crosses I-80 (the Ohio Turnpike), there is no interchange and one must drive a couple of miles through surface streets between I-75 exit 6 and I-80 exit 59.
Michigan
The 16.99 mile Interstate 475 in Michigan is a bypass which serves the downtown area of Flint, Michigan while I-75 passes through the west side of the city.
