Thanks a lot for providing this fine route! The route provided features both a long bike path (yay, no cars!) when in the Philly area, and elsewhere highways with wide shoulders, especially in Lancaster County. I used the route provided east of its intersection with Highway 322, along with Highway 322, to successfully undertake a round trip journey from Harrisburg to Philly this past weekend. Lots and lots of bicyclists in Philly use the bike path part of the route for their routine training. No very bad sections of road that I recall.
