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.

Bittle of Hardin Valley and Knoxville mayor Victor Ashe,[3] the project was scrapped by the Tennessee Department of Transportation (TDOT) in 2010.

Upon completion, this route was expected to be added into the National Highway System, and would have also been designated as a Tennessee Scenic Parkway.

[1] This route was also being studied by TDOT as a potential toll road, and may have been planned to be extended to I-40 near exit 407 in Sevierville, replacing the bypass designation of I-640.

The "no build" option was selected because projections showed that it would divert less traffic from I-40/I-75 than previously expected, and the estimated one billion dollar expense was deemed prohibitive.
