= Interstate 276 =

Starting at the Valley Forge interchange, the turnpike is designated as I-276 and becomes a six-lane road serving as a suburban commuter highway. The road comes to a bridge over SEPTA's Norristown High Speed Line and runs parallel to Norfolk Southern's Dale Secondary rail line, which is located south of the road. The turnpike crosses Norfolk Southern's Harrisburg Line, the Schuylkill River, and SEPTA's Manayunk/Norristown Line on the Schuylkill River Bridge near Norristown. A short distance later, the road passes over the Schuylkill River Trail and Norfolk Southern's Morrisville Connecting Track on the Schuylkill River Bridge before the parallel Dale Secondary rail line heads further south from the road.

In Plymouth Meeting, an interchange with Germantown Pike provides access to Norristown before the roadway reaches the Mid-County Interchange. This interchange connects to I-476, which heads south as the Mid-County Expressway (commonly known as the "Blue Route") and north as the Northeast Extension of the turnpike; connecting the mainline turnpike to the Lehigh Valley and the Pocono Mountains regions of Pennsylvania.

After the Mid-County Interchange, the mainline turnpike heads east through the northern suburbs of Philadelphia. In Fort Washington, the highway passes over SEPTA's Lansdale/Doylestown Line before it has an interchange with PA 309. At this point, the road becomes parallel to Norfolk Southern's Morrisville Line, which is located a short distance to the south of the road. 1 mi later, the turnpike has a westbound exit and entrance for Virginia Drive. In Willow Grove, the highway reaches the PA 611 exit before passing over SEPTA's Warminster Line. The turnpike continues through more suburban areas, crossing into Bucks County and coming to a bridge over Norfolk Southern's Morrisville Line. Farther east, the roadway passes over SEPTA's West Trenton Line. In Bensalem Township, the highway comes to a bridge over CSX's Trenton Subdivision rail line before reaching an interchange with US 1, which provides access to Philadelphia.

The highway narrows back to four lanes before an eastbound exit and entrance with PA 132. A short distance later, the turnpike arrives at the eastern end of the distance-based toll system at the Neshaminy Falls main line toll plaza. After passing through more suburbs, the road reaches a partial interchange with I-95, where it crosses under I-295 with no access; this interchange has access from the westbound turnpike to southbound I-95 and from northbound I-95 to the eastbound turnpike. At this point, I-276 ends and the Pennsylvania Turnpike becomes part of I-95. Here, signage indicates the westbound turnpike as a left exit from southbound I-95, using I-95 milepost exit number 40. This is the only place where continuing on the mainline turnpike is signed as an exit.

After joining I-95, the remaining 3 mi of road uses I-95's mileposts and exit numbers and is not directly signed as the Pennsylvania Turnpike, though it is still considered part of the mainline turnpike. Continuing east, the turnpike reaches its final interchange, providing access to US 13 near Bristol. Following this, the road passes over an East Penn Railroad line before it comes to the westbound all-electronic Delaware River Bridge toll gantry. After this, the highway crosses the Delaware Canal and Amtrak's Northeast Corridor rail line before heading across the Delaware River into New Jersey on the Delaware River–Turnpike Toll Bridge. At this point, the Pennsylvania Turnpike ends, and I-95 continues east (north) as the Pearl Harbor Memorial Extension of the New Jersey Turnpike, which connects to the mainline of the New Jersey Turnpike.
