Interstate 140 Tennessee


Interstate 140 is both the Pellissippi Parkway and Tennessee 162. The suburban type freeway angles southeast from SR 162 and Interstates 40 & 75, west of Knoxville, to a bridge across the Tennessee River and SR 333 (Topside Road). The interstate designation ends at U.S. 129, while the SR 162 freeway extends southward to SR 33 near Alcoa.

An extension of SR 162 will eventually lengthen the route south to U.S. 321 as part of a through route to Great Smoky Mountains National Park. This function will be further enhanced with the completion of the Foothills Parkway from U.S. 321 southwest to U.S. 129. Maintained by the National Park Service, the 1.65 mile long gap in the parkway will bridged by June 2017, though final paving for the 16-mile segment is a future project.12


Interstate 140 was approved by the AASHTO Special Committee on Route Numbering on June 13, 1992. The first portion of Interstate 140 opened December 4, 1992 between Northside Drive and U.S. 129 (Alcoa Highway), a 6.6-mile segment including the Fort Loudon Lake bridge.4 The bridge and a stretch of freeway south to Wrights Ferry Road was completed in August 1990 but not opened to traffic. The second section to open extended I-140 northward four miles to Kingston Pike (U.S. 11 & 70) on October 6, 1993.7 and the I-140 link to Interstates 40 & 75 and SR 162 followed on December 16, 19968, though all of the ramps between the two freeways were not completed until spring of 1997. A 1.1-mile extension east from U.S. 129 (Alcoa Highway) to Cusick Road opened by December 22, 1996.8

Work on the $11.7-million extension of SR 162 to Old Knoxville Highway (SR 33) began in 2000 and was completed August 15, 2005.9 Interstate 140 was resurfaced between May and September 2004.3

The Pellissippi Parkway was planned for a 4.5-mile extension southeast to U.S. 3215, east of Maryville. TDOT already planned the route and was set to commence with construction. However because of a lawsuit filed against the Department of Transportation, construction never began. The lawsuit emanated from the Citizens Against the Pellissippi Parkway Extension (CAPPE) who argued that the Tennessee Department of Transportation had not done an adequate Environmental Impact Statement (EIS) for the planned freeway. A federal judge agreed to place an injunction against TDOT in 2002 which actively halted any construction.

In August 2004, the U.S. District Court issued an order modifying its previous injunction, which allowed TDOT to reissue its environmental documents regarding SR 162 / Pellissippi Parkway. On September 27, 2004, TDOT announced the preparation of the environmental impact statement for the extension.4 A Draft Environmental Impact Statement (DEIS) was approved on April 14, 2010. The Final EIS was approved on September 10, 2015. Alternate A was endorsed by the Maryville City Council on October 4, 2011 and the Alcoa City Commission on October 11, 2011. The Blount County Commission voted to send a recommendation for Alternate A on October 11 as well.10 A record of decision (ROD) was expected by summer 2016.
