It runs from I-80 near Sharon south and east to a junction with the Pennsylvania Turnpike in Monroeville, after having crossed the Pennsylvania Turnpike at an interchange in Big Beaver. The route serves Pittsburgh and its surrounding areas and is the main access road to Pittsburgh International Airport (PIT). Portions of the route are known as the Beaver Valley Expressway, Southern Expressway, and Airport Parkway. Within Allegheny County, the route runs along the majority of the Penn-Lincoln Parkway, known locally as Parkway West and Parkway East. It is currently the ninth-longest auxiliary Interstate route in the system and second only to I-476 within Pennsylvania.

I-480 is one of 13 auxiliary Interstate Highways in the state. The western terminus of I-480 is an interchange with I-80 and the Ohio Turnpike in North Ridgeville. Starting east through suburban Lorain County, I-480 enters Cuyahoga County, then approaches Cleveland Hopkins International Airport, which serves as the primary airport for Northeast Ohio. After traversing Brooklyn and crossing the Cuyahoga River on the Valley View Bridge, the highway continues east toward the communities of Bedford and Twinsburg toward its eastern terminus at I-80 and the Ohio Turnpike in Streetsboro. On its route, I-480 crosses I-71 and I-77 and is concurrent with I-271 for approximately four miles (6.4 km).

The Pennsylvania Turnpike/Interstate 95 Interchange Project is an ongoing road construction project to build an interchange where Interstate 95 (I-95) crosses the Pennsylvania Turnpike in Bristol Township, Bucks County, Pennsylvania, in the United States. With the opening of a pair of flyover ramps–one connecting I-95 northbound with the eastbound turnpike and the other connecting the westbound turnpike with I-95 southbound, the first stage of the project was substantially completed in 2018 at a cost of about $553 million, with some cleanups to connecting roads completed in 2021. Construction of the remaining ramps is expected to begin when funding is available.
The Delaware River–Turnpike Toll Bridge is a four-lane, steel through arch bridge crossing the Delaware River between Burlington Township, Burlington County, New Jersey and Bristol Township, Bucks County, Pennsylvania. As a part of Interstate 95 (I-95), it is a major highway link between Philadelphia and New York City. The bridge also connects the Pennsylvania Turnpike's east-west mainline with the main trunk of the New Jersey Turnpike, via the Pearl Harbor Memorial Turnpike Extension. Tolls are collected only in the west/southbound direction via electronic toll collection.
