I-376 begins at a [[cloverleaf interchange]] with [[Interstate 80 in Pennsylvania|I-80]] and [[Pennsylvania Route 760|PA&nbsp;760]] located {{Convert|4|mi|km|spell=in}} east of [[Ohio]] within the [[Glaciated Allegheny Plateau]]. From there, it travels in a southerly direction on the Beaver Valley Expressway, a four-lane freeway with a wide grass median. Paralleling [[Pennsylvania Route 18|PA&nbsp;18]], I-376 has its first interchange with that state highway in [[West Middlesex, Pennsylvania|West Middlesex]].

I-376 soon meets [[U.S. Route 422 in Pennsylvania|US&nbsp;422]] and forms an overlap with that highway along the west side of [[New Castle, Pennsylvania|New Castle]]. After an interchange with [[U.S. Route 224 in Pennsylvania|US&nbsp;224]] in [[Union Township, Lawrence County, Pennsylvania|Union Township]], I-376 eastbound splits from US&nbsp;422 at a [[trumpet interchange]] southwest of the city in [[Taylor Township, Lawrence County, Pennsylvania|Taylor Township]]. At this point, I-376 becomes a [[toll road]] officially named the James E. Ross Highway.

I-376 continues southward, still paralleled by PA&nbsp;18 and the [[Beaver River (Pennsylvania)|Beaver River]] to the east. Shortly after entering [[Beaver County, Pennsylvania|Beaver County]] near [[Koppel, Pennsylvania|Koppel]], the route connects to its parent route [[Interstate 76 in Pennsylvania|I-76]] ([[Pennsylvania Turnpike]]) for the first time at an interchange which also provides access to [[Pennsylvania Route 351|PA&nbsp;351]]. Around this area, I-376 crosses into the [[Unglaciated Allegheny Plateau]], where it remains for the remainder of its length.

I-376 then passes to the east of [[West Mayfield, Pennsylvania|West Mayfield]] and becomes a non-tolled highway again at its first interchange with [[Pennsylvania Route 51|PA&nbsp;51]] in [[Chippewa Township, Beaver County, Pennsylvania|Chippewa Township]], just west of [[Beaver Falls, Pennsylvania|Beaver Falls]]. The freeway then weaves through mountainous terrain, interchanging with [[Pennsylvania Route 68|PA&nbsp;68]] in [[Vanport Township, Beaver County, Pennsylvania|Vanport]] just before crossing the [[Vanport Bridge]] over the [[Ohio River]]. It then has its second interchange with PA&nbsp;18 near [[Kobuta, Pennsylvania|Kobuta]] and continues south from there. I-376 passes to the west of [[Aliquippa, Pennsylvania|Aliquippa]] before leaving Beaver County and entering [[Allegheny County, Pennsylvania|Allegheny County]].

Approaching [[Pittsburgh International Airport|PIT]], I-376 bends south-southwest and becomes the Southern Expressway, while the Beaver Valley Expressway diverges to the southeast along [[Interstate 376 Business|I-376 Business]] (I-376 Bus). I-376 circles around the southern edge of the airport, intersecting the western terminus of the Southern Beltway ([[Pennsylvania Route 576|PA Turnpike&nbsp;576]]) at the main entrance to PIT before recombining with I-376 Bus and becoming the Airport Parkway, still four lanes and with a narrow median.
