Interstate 140 Tennessee
Interstate 140 is both the Pellissippi Parkway and Tennessee State Route 162. The suburban freeway angles southeast from SR 162 and I-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 continues southward to SR 33 near Alcoa.
The State Route 162 Pellissippi Parkway Extension will lengthen the highway southeast to U.S. 321. Providing part of a through route to Great Smoky Mountains National Park, Pellissippi Parkway will further improve traffic with the completion of 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 opened to the public on November 10, 2018. Costing $321 million, final paving for the 16-mile segment was funded by a Transportation Investment Generating Economic Recovery (TIGER) VIII grant, the NPS Federal Lands Transportation Program and the state of Tennessee.12
The Tennessee IMPROVE Act signed on April 26, 2017 estimated $61 million for completion of Pellissippi Parkway Extension. Funds for right-of-way acquisition and staged construction are budgeted in the Tennessee Department of Transportation (TDOT) three year plan for Fiscal Year 2020.13
Interstate 140 was approved by the AASHTO Special Committee on Route Numbering on June 13, 1992. The first portion of the freeway finished was a 6.6-mile segment including the Fort Loudon Lake bridge. Traveling north from U.S. 129 (Alcoa Highway) to Northside Drive, the section was completed December 4, 1992.4 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 of I-140 extended northward four miles to Kingston Pike (U.S. 11 & 70) on October 6, 1993.7.
The I-140 link with I-40/75 and SR 162 followed on December 16, 19968, though all ramps between the two freeways were not completed until Spring 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. It was finished on August 15, 2005.9 Interstate 140 was resurfaced between May and September 2004.3

State Route 162 Pellissippi Parkway Extension
The Tennessee Department of Transportation (TDOT) plans further extended Pellissippi Parkway southeast 4.38 miles to U.S. 321 east of Maryville.5 TDOT was set to commence with construction but never did due to a lawsuit filed by the Citizens Against the Pellissippi Parkway Extension (CAPPE) on June 7, 2002. CAPPE argued that TDOT had not completed an adequate Environmental Impact Statement (EIS) for the planned roadway. A federal judge agreed and placed an injunction against TDOT on July 17, 2002, halting construction activities.13
The U.S. District Court issued an order in August 2004 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
Approval for the Pellissippi Parkway Draft Environmental Impact Statement (DEIS) followed on April 14, 2010 and the Final EIS (FEIS) 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 The record of decision (ROD) for the project was signed by FHWA on August 31, 2017.
