Harrisburg International Airport is located just outside the city in Middletown. Directly in center city Harrisburg is the Harrisburg Transportation Center, which serves as an Amtrak and Greyhound/Trailways hub. Williamsport and Selinsgrove both have their own regional airports. The valley is connected by Pennsylvania state routes 11 & 15 from north to south. The Harrisburg area also has access to Interstates 81 and 83, state routes 322 and 22, and the Pennsylvania turnpike to points east and west.
