Interstate 475 (Georgia)
Interstate 475 (I-475) is a 15.83-mile-long (25.48 km) auxiliary Interstate Highway in Georgia, splitting off from I-75/State Route 540 (SR 540) and bypassing Macon. It is also unsigned State Route 408 (SR 408). This is the preferred route for through traffic, as I-75 enters Downtown Macon and reduces to four lanes, and has a 60-mile-per-hour (97 km/h) speed limit, in addition to the highway interchange with I-16.
