Which route.
EZ Pass a year ago for the Maryland Bay Bridge was $18 for a two axle trailer pulled by a two axle pickup. DE-1 was $9 and the Newburgh-Beacon Bridge across the Hudson was $3.05 for the same towing configuration. The two bridges were east bound tolls only. We avoided all the other toll roads by going farther north (and our destination was in CT just off I-84).
The Delaware Memorial Bridge toll is $10 for a two axle trailer - but that is collected west bound only, not east bound.
However on an overnight trip to Newark (don't ask) - we spent $7.20 on the NJ Turnpike and $12.50 to cross the George Washington Bridge / I-95 (bridge again an east-bound only toll) for a passenger car. For a two axle trailer - it would be a whopping $72 or $31.50 depending upon details of their rules.
A quick check shows the NJ Turnpike from the Delaware Bridge to the GW Bridge would be $39 one-way for the trip for a two axle trailer. Plus the GW Bridge toll.
So with EZ-Pass - bridges only if you take I-95 to the DE bridge:
Min - $3.05 + $10 = $13.05
Max - $72.00 + $10 = $82.00
NJT - $39 each way
