I did the math, and with the current toll increases and proposed rates to drive in midtown Manhattan next year, a commuter from Elizabeth NJ to Midtown would pay approximately $85 in tolls in total to commute both ways. (Using the Optimal Route of I-278/Battery tunnel)
First of all, if you're commuting to Manhattan on a daily basis and you insist on getting there by car instead of by train, you need to seriously reevaluate your choices in life.
Second of all, even if you absolutely must make that trip by car, that is not the optimal route. It would make more sense to take the turnpike north and then go in either the Holland or Lincoln Tunnel (depending on where exactly in Manhattan you're headed).
Third of all, even for your weird route that passes through more tolls than necessary, it wouldn't be $85. The peak toll on the Goethals Bridge is $14.75, eastbound only. The Verrazzanno and Battery Tunnel are both $6.94 each way. Exactly what the congestion fee will end up being is TBD but at most it will be $23. That's $65.51 total.
Yes, it would be more if you don't have a NY E-Zpass, but if you're making trips like this regularly you're a damn fool if you don't. Anyone can get one.
