Tennessee State Route 475

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 Bull Run, then join I-75 again northwest of Heiskell.[1]

Route description

I-475/SR-475 was proposed as a four-lane divided highway with full access control and a 70 mph (110 km/h) design speed. 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 or State Scenic Highway.[2] This route was also being studied by TDOT as a potential toll corridor and may have been planned to be extended to I-40 near mile marker 407.[2] The route would have served as an outer bypass to Interstate 640.

History

With the idea originally conceived in the mid 1990s, the Knoxville Parkway was dubbed the "orange route" in the press. The route was cancelled on June 25, 2010 due to changing traffic needs and high cost. 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.[3]

gollark: Personally, if I had encountered this code somehow, I would dispose of it and rewrite it entirely.
gollark: It directly meddles with `innerHTML`s quite a lot.
gollark: The frontend code is actually horribly vulnerable to XSS.
gollark: The PotatOS stuff is pretty safe, I think, since the signatures are only generated offline in the Site Null vault.
gollark: More ellipses → more security. This is known.
