Interstate 475 (I-475)/State Route 475 (SR 475) was a proposed Interstate highway and state highway in Knox and Anderson counties, within the eastern part of the U.S. state of Tennessee. The proposed route would have allowed through traffic on I-75 to bypass the city of Knoxville. It was planned to begin at the I-40/I-75 split and travel northeast through the communities of Solway and , then join I-75 again northwest of Heiskell.
