The easiest route to the site of the Flight 93 memorial:
Take Ohio Turnpike and then Pennsylvania Turnpike, getting off at Somerset Exit 10.
Go straight ahead, through two traffic lights. You'll be on Route 31 east.
Take Route 31 east from Somerset to the first sign pointing to Shanksville, which is Stutzmantown Road.
After four miles, you'll see the Flight 93 Memorial Chapel on the left.
Save that stop for your return trip.
Follow Stutzmantown Road into Shanksville (six miles from Route 31) and turn left at Lambertsville Road.
Follow Lambertsville Road to Skyline Road and turn right.
Follow that road until you see the memorial down the hill on the right. It's four miles from Shanksville to the site.
