The Pellissippi Parkway is a highway in Knox and Blount counties in Tennessee. It extends from SR 62 ( Oak Ridge Highway) at Solway in Knox County to a terminus east of US 129 (Alcoa Highway) at SR 33 (Old Knoxville Highway) in Blount County. The central portion of the Pellissippi Parkway is included in the Interstate Highway system and is designated Interstate 140 (I-140), while portions at either end (a 5.9-mile (9.5 km) long section in Knox County and a short section in Blount County) are designated State Route 162 (SR 162), a north–south primary highway.
Pellissippi Parkway comprises I-140 and two sections of SR 162 that seamlessly extend from either end of the Interstate highway. The northern segment of SR 162 runs 5.9 miles (9.5 km) from SR 62 at Solway south to I-40 and I-75 in Knoxville.  I-140 has a length of 11.17 miles (17.98 km) from the junction with I-40 and I-75 to US 129 in Alcoa.   The southern segment of SR 162 begins at US 129 and runs 2.7 miles (4.3 km) to SR 33 within Alcoa.  Pellissippi Parkway from Solway to US 129 is a part of the National Highway System.  The predominant roadway configuration along the route is a four-lane divided cross-section. 
Pellissippi Parkway begins at SR 162's northern terminus at a directional interchange with SR 62 (Oak Ridge Highway) at the east end of the village of Solway on the east side of the Clinch River from Oak Ridge. There is no direct access from westbound SR 62 to the parkway. Pellissippi Parkway heads southeast as a limited-access four-lane divided highway. The highway crosses Beaver Creek and has a four-ramp partial cloverleaf interchange with Hardin Valley Road, which leads to Pellissippi State Community College. Pellissippi Parkway has another partial cloverleaf interchange with SR 131 (Lovell Road).
The highway becomes a freeway at its last at-grade intersection just northwest of its partial cloverleaf interchange with Dutchtown Road. There, Pellissippi Parkway enters the western end of the city of Knoxville, expands to six lanes, and is paralleled on both sides by frontage roads south to the parkway's interchange with I-40 and I-75, where SR 162's northern segment ends and I-140 begins. That interchange is a cloverleaf interchange with a flyover ramp from southbound SR 162 toward eastbound I-40 and northbound I-75, which head concurrently toward downtown Knoxville. 
Pellissippi Parkway continues south through a partial cloverleaf interchange with Kingston Pike, which carries US 11 and US 70. South of Kingston Pike, the freeway passes along a sliver of the city of Knoxville that follows the freeway to the Tennessee River. Pellissippi Parkway crosses a Norfolk Southern Railway line and the Sinking Creek arm of Fort Loudon Lake ahead of its diamond interchange with Westland Drive. The freeway curves east within its diamond interchange with SR 332 (Northshore Drive); the interchange includes a ramp from the eastbound parkway to Town Center Boulevard. Pellissippi Parkway veers south onto a peninsula within a bend of the Tennessee River, then curves east again to cross the river, which forms the Knox–Blount county line.
At the east side of the river, Pellissippi Parkway enters the city of Alcoa, within which the highway remains to its eastern end. The freeway has a diamond interchange with SR 333 (Topside Road) and crosses a CSX rail line. Pellissippi Parkway curves southeast through a cloverleaf interchange with US 129 (Alcoa Highway), where I-140 ends and the southern segment of SR 162 begins. The freeway has an southbound-only exit and northbound-only entrance from and to Cusick Road and crosses a Norfolk Southern rail line before reaching its terminus at a half-diamond interchange at SR 33 (Old Knoxville Highway) in Eagleton Village. 
When first built, the Pellissippi Parkway was a four-lane divided highway in Knox County, extending from State Route 62 at Solway to an interchange with I-40/ I-75 in western Knox County. This segment was completed in 1971.  Plans for extending the Pellissippi Parkway from I-40/I-75 in Knox County into Blount County first appeared in a 1973 statewide transportation plan, and in April 1975, the Tennessee General Assembly passed a resolution authorizing TDOT to study the possibility of extending the route east to the Alcoa Highway.  The extension did not receive funding until the passage of the Better Roads Program of 1986, an initiative by then-governor Lamar Alexander to fund a backlog of needed road projects throughout the state.  This part of the parkway was constructed in four sections beginning in 1987.  The first section, which crosses the Tennessee River to connect Northshore Drive in Knox County with US 129 in Blount County, was completed in 1992, providing more efficient access to the McGhee Tyson Airport from Oak Ridge and Farragut.  The Mabry Hood House, an antebellum home located on the south side of Kingston Pike, was demolished in the project to extend the Pellissippi Parkway south of I-40/I-75. The next section of the project, which opened in 1997, installed a new interchange with I-40/I-75 and provided a limited-access connection from that interchange to the Northshore Drive interchange.  In 2003 a third section was opened in Blount County, extending from US 129 to Cusick Road, and the most recent section, from Cusick Road to Tennessee SR 33, opened in late 2005.  Plans call for extending the highway eastward about 4.4 miles (7.1 km) to U.S. Route 321 (Tennessee State Route 73) in Blount County. 
As of 2003, SR 162 was applied to an 5.9-mile (9.5 km) long route in Knox County; its southern terminus was with I-40 where I-140 begins, and its northern terminus was with State Route 62 at Solway. Additionally, as of 2005 the eastward highway extension of I-140 east of U.S. Route 129 (Alcoa Highway) in Blount County, Tennessee was signed as SR 162. Originally, the highway that is now designated as I-140 was designated SR 162 and Pellissippi Parkway. The state route designation was dropped when the central portion was accepted into the Interstate Highway system as I-140, but the entire route of SR 162 and I-140 from Solway to US 129 is still known as Pellissippi Parkway.
Pellissippi (also spelled "Pelisipi") appears on early maps as the name of the Clinch River.
A 4.4 mile extension project in Blount County from SR 33 (Old Knoxville Highway) to a terminus at SR 73/US 321 East (Lamar Alexander Parkway) between Maryville & Walland has undergone a number of delays and court reviews since the 1990s. An exit is proposed at US 411 in Maryville.
