We would like to take a scenic route to reading PA from Fredericksburg...alternate to I 95. Thanks!
You can take US17 north out of Fredericksburg to US 15. Follow US15 to Harrisburg, PA. From Harrisburg you have several options to continue on to Reading. The PA turnpike I76 intersects with US15 just south of Harrisburg and would be one of the more efficient routes to Reading. If you want to avoid the turnpike tolls, let me know and I can suggest alternate routes.
I would also take US 17 North to US 15 North to the PA Turnpike. In fact, a friend of mine who lives in Reading has family in Germantown, MD and he always takes 15 to I-270 in Frederick. Just make sure you time your arrival through Frederick and Leesburg right; time it wrong and it could take you an extra hour. Sometimes, this route is even faster than I-95 if there's a major backup or accident in DC. It's fairly free-flowing outside of Leesburg and Frederick.
