1. Apparently, I-95 in Pennsylvania is not I-95 in Jersey. Go figure.
2. Every freeway has multiple toll booth(s), but the quality of the roads does not reflect the exorbitant tolls charged to drive on them. Tolls between Philly and Jersey amount to about $15 one-way. Caveat driver.
3. There is no, repeat NO, public transport system that provides a practical alternative to driving. Refer #2 to understand why if you have to drive, you're almost signing up to be waylaid by the toll booths. State sponsored daylight and night-time robbery at its insidious best. I said "practical"; Amtrak is neither practical - train schedules and trip durations are from an era that passed in 1975 - nor cost-effective.
4. Did I say something about tolls yet? Another point of reference - NYC congestion tax is now $12, but the roads into the city are 10 times worse-for-driving than the 520 bridge at its worst!
5. Finally, I mean I can go on but for the purposes of brevity, you might argue that there are state roads that are not toll-ways. Right these exist; wrong if you think they are viable alternatives. Expect to drive for at least 45 minutes longer and stop at ludicrously out-of-sync stop lights if you choose state routes. And oh yeah, people can join these roads from side-rights on the right, cut you off as they take left turns into side roads, or do both at the same time with impunity.
But wait, this is the right coast. Or whatever.
