Harrisburg has always had traffic problems and mostly because of road construction. For years, it was US 322, but that's finally finished. Then it was the I-83/I-81 interchange. FINALLY, they put an express lane down the median to fix that problem. And a constant nuisance is rt 11/15 around Marysville and Enola. BUT there's a nice way around that most people don't know if they are just passing through.
If you're coming up rt 15 from Maryland and approaching Harrisburg, DO NOT exit off to keep following this highway.
Stay STRAIGHT into the city, toward the M. Harvey Taylor Bridge. Cross over it, onto Forrester.
Take Forrester to the end, turn L onto 7th and immediately right onto Herr St.
At the stoplight on Herr, take a L onto Cameron. This will put you onto 322W heading toward State College. Or you can get onto 81N and S to 83S to 283, the airport and turnpike
322 is 4 lane divided, 55mph highway where NO ONE drives less than 80mph. No stoplights, no reduced speed zones.
You'll cross over the Duncannon Bridge and see the exit shortly thereafter for 11/15 N (Selinsgrove) where you'll hook back up with it.
This avoids ALL congestion--the city is never crowded and it saves about 20 mins at the very least.
(Rt 11/15 is the most convenient way to get from the DC area or points south up to central PA and central NY state...pretty heavily traveled road.)
I went down on a yellow school bus. While on the bus I sat in the back with my friends Clyde, Adam, and Kammy. Clyde and me picked on eachother the whole way down. We went past a farm and smelt some cow manure and I told him he should check his pants. Then he saw a duck and said it was my brother and we both laughed the whole time. Adam said the whole bus was insane. And I told him that I was sane and he said "oh ok at least the is one sane person on this bus" Bus rides are usly a lot of fun when you go with a group of friends and sometimes even when you don't know anyone it is alright to talk to someone and get to know them.
