Tennessee State Route 475

Interstate 475 (I-475)/State Route 475 (SR 475), officially known as the Knoxville Parkway and commonly known as the Orange Route, was a proposed Interstate Highway and state route in Loudon, Knox, Anderson, Grainger, Jefferson and Sevier 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 Knoxville-Knox County urbanized area. If constructed, SR 475 was to begin at the I-40/I-75 junction near Farragut, and travel northeast through the communities of Hardin Valley, Solway and Claxton, then join I-75 again northwest of Heiskell. It was also considered to be extended to I-40 at exit 407, serving as a northern semi-beltway in the Knoxville area. Driven by opposition spearheaded by state representative H.E. Bittle of Hardin Valley and Knoxville mayor Victor Ashe, the project was scrapped by the Tennessee Department of Transportation (TDOT) in 2010.
