@Sublime one

See them rivers? Those are all big enough that there are only limited number of crossing locations.

Those going into the Delaware River all form deep valleys.
Allentown to Harrisburg the mountain ridges of the Appalachians are the opposite diagonal.
That's the only way to make sense of Pennsylvania's geography and resulting roadways.
A lot of diagonals.
This map is cool.
