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 per Interstate design standards. 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.[1]
History
This section needs expansion. You can help by adding to it. (June 2008)
With the idea originally conceived in the mid 1990s, the Knoxville Parkway was dubbed the Orange Route in local press, prominently the Knoxville News Sentinel. The route was cancelled on June 25, 2010, due to changing traffic needs and high design and construction. 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.[4]
