Route description[edit]

Maryland to Interstate 78[edit]

I-81 northbound at western terminus of I-78

I-81 enters Pennsylvania at the Maryland state line about 13 miles (21 km) south of Chambersburg. In Chambersburg at mile marker 16, it meets with a major highway; U.S. Route 30 (the Chambersburg Pike to Gettysburg). About a mile north of Carlisle at exit 52, it meets with U.S. Route 11, which takes passengers to the Pennsylvania Turnpike/ Interstate 76, since I-81 has no direct interchange with I-76. The stretch of US 11 connecting I-81 to I-76 is known locally as the "Miracle Mile" since it contains plenty of traveler services including restaurants, gas stations, lodging, truck stops, shops, etc.[2] From here, I-81 travels in an almost precisely east–west direction for the next 37 miles (until exit 89). At mile marker 59, it has an interchange with the western terminus of Pennsylvania Route 581. I-81 becomes the Capital Beltway from exit 59 to exit 70. As passengers approach exit 67, a major complex interchange is seen. The interchange consists of U.S. Route 22 and U.S. Route 322; U.S. Route 322 merges with Interstate 81. Exit 70 is the eastern terminus of the US 322 concurrency and the northern terminus of Interstate 83, and is located in Colonial Park. For the entire segment between the Mason-Dixon Line and Interstate 78, I-81 runs through the Great Valley. North of Harrisburg between Interstate 83/U.S. Route 322 and Interstate 78, the highway passes near Hershey and Fort Indiantown Gap.

Interstate 78 to New York State[edit]

I-81 northbound approaching Central Scranton Expressway in Scranton

At mile marker 89, I-81 meets the western terminus of I-78; I-78 picks up the eastward route through the Great Valley and heads toward Allentown and New York City, while I-81 turns back northward, cutting through the Blue Mountain at Swatara Gap. From mile marker 141 to mile marker 146; I-81 passes near the city of Hazleton. At exit 151, I-81 meets a major interstate; Interstate 80. As motorists enter Wilkes-Barre at mile marker 165, Interstate 81 merges with a major Pennsylvania route for 5 miles (8.0 km); Pennsylvania Route 309. At exit 175, I-81 meets with Pennsylvania Route 315, which will lead passengers to the Northeast Extension of the Pennsylvania Turnpike. In Scranton at mile marker 185, there is a short freeway called the Central Scranton Expressway which will lead passengers into downtown Scranton. At mile marker 187, I-81 is at the Throop Dunmore Interchange which consists of Interstate 84, Interstate 380, and U.S. Route 6. US 6 merges with I-81 for 7 miles (11 km) from mile marker 187 to mile marker 194. At mile marker 194, is the northern terminus of Interstate 476 which is the north east extension of the Pennsylvania Turnpike. The last exit in Pennsylvania is exit 230 which is Pennsylvania Route 171 near Hallstead. 4 miles (6.4 km) north of exit 230, passengers have entered the state of New York.


On May 9, 2013, a tanker crashed and caught fire at the interchange between I-81 and US 22/US 322 in Harrisburg. The fire damaged the bridges carrying westbound US 22/US 322 and a ramp over I-81. At least one of those bridges, carrying US 22 eastbound over I-81 and several ramps, and possibly another, the ramp carrying traffic from I-81 northbound to US 22/US 322 westbound, will have to be demolished and replaced. The fire resulted in about ten miles of I-81 being closed in both directions, with traffic being diverted along the southern portion of the Capital Beltway.[3][4] The highway would not be fully reopened to traffic until the evening of May 13.[5]
