Pennsylvania is home to ten auxiliary interstates. Three of these highways are in the Philadelphia area. Interstate 276 begins at I-76 in King of Prussia and travels east for 33 miles before crossing the Delaware River into New Jersey. Traveling north-south for 132 miles in the eastern part of the state is Interstate 476. It begins at I-81 near Clark's Summit and runs south to join I-95 near Chester. Less than seven miles of Interstate 676 serve to connect I-76 in Philadelphia to I-76 in Camden via the Ben Franklin Bridge.

In Reading Interstate 176 uses its just over eleven miles to connect the Pennsylvania Turnpike (I-76) to US 422. Interstate 180 in Williamsport leaves I-80 and travels north for 29 miles to US 15. Connecting I-80 to I-81 is Interstate 380. This highway runs north-south for 25 miles south of Scranton. Finally, Interstate 283 near Harrisburg uses less than three miles to connect I-83 to I-76.

In the Pittsburgh area Interstate 376 runs in a north-south direction for 81 miles parallel to Interstate 79 which is to the east. It connects I-80 with I-76 and joins New Castle and Beaver Falls. This scenic highway provides an alternate route for motorists to avoid Pittsburgh traffic. It also provides a route to the Pittsburgh International Airport. Joining I-376 to I-79 is Interstate 279. It travels on a diagonal for 13 miles north of the Ohio River. The last highway is Interstate 579. This road is less than two miles in length and joins PA 885 to I-279.
