Interstate 474 (I-474) is an Interstate Highway loop route that provides a southwestern bypass around the north-central Illinois city of Peoria. I-474's parent Interstate is I-74. As the first digit of the Interstate's number is even, it follows the established convention of providing a loop around a city. I-474 is 14.88 miles (23.95 km) long. I-474 is the highest numbered route in the state of Illinois. It is also, excluding the proposed I-274 in North Carolina, the only auxiliary route of I-74.
