The Pellissippi Parkway is a major highway in Knox and Blount counties in the Knoxville metropolitan area in Tennessee that extends 19.75 miles (31.78 km) from State Route 62 at Solway to SR 33 in Alcoa. It provides access to the cities of Oak Ridge and Maryville from Interstates 40 and 75 in the western part of Knoxville and also serves a major corridor that includes Oak Ridge National Laboratory, Y-12 National Security Complex, and a number of science and technology firms. The central portion of the Pellissippi Parkway is included in the Interstate Highway System and is designated Interstate 140 (I-140), while the remainder is designated as State Route 162 (SR 162). The entire highway is part of the National Highway System, a national network of roads identified as important to the national economy, defense, and mobility.^[3]^[4] It takes its name from an older name for the Clinch River of Native American origin.

The Pellissippi Parkway was initially constructed between I-40/I-75 and Solway from 1970 to 1973 in order to improve access between Knoxville and Oak Ridge. A proposal to extend the highway to US 129 arose while the initial section was under construction, and this occurred in multiple segments between 1987 and 1996. The parkway was extended to its current eastern terminus in two sections, which opened in 1996 and 2005, and is currently planned to be extended approximately 4 miles (6.4 km) to US 321. This plan has been the subject of intense community opposition from locals, however, and has been repeatedly delayed as a result.
