Interstate 475 (I-475) is an Interstate Highway in Ohio that is a 20.37-mile (32.78 km) western bypass of Toledo. The southern terminus is I-75 exit 192 near Perrysburg. From the southern terminus to exit 14, I-475 is co-signed with US Route 23 (US 23), and is signed the north/south section of I-475. From exit 14 to the eastern (northernmost) terminus at I-75 exit 204 in central Toledo, (north of downtown), it is signed the east/west section of I-475.
Although I-475 crosses I-80/I-90 (the Ohio Turnpike), there is no interchange and one must drive a couple of miles through surface streets between I-475 exit 6 and I-80/I-90 exit 59.
I-475 is named the Rosa Parks Highway in honor of Rosa Parks, who had helped organize the Montgomery bus boycott.
I-475 is a half-beltway bypassing downtown Toledo on its western side as mostly a north–south segment and a largely east–west segment on the north side of Toledo. It has almost a half-square shape on the map consisting of the top and left sides of the square. It is much less direct than its parent I-75 through Toledo; the entire route of I-475 uses 20 miles (32 km) to connect exits 12 miles (19 km) apart on I-75.
I-475 parallels what was US 23 on its north–south segment (US 23 has been realigned to it); it has Ann Arbor, Michigan, as a control city northbound (via US 23) and Columbus and Dayton as control cities southbound; it reaches neither of the three cities. On its northern segment it parallels State Route 120 (SR 120) and has Toledo as a control city to the east. Rural when built, it has much suburban-style development along its route.
