Unlike your standard $0.50 or $1 toll booth, these guys arenât cheap. The George Washington toll is $8.00 and the Throgs Neck toll is $5.50. Round trip, I paid $19.00 in tolls and it got me to wondering just how much these toll booths collect each and every day. On the George Washington Bridge, there are 23 cash toll booths as well as 8 EZ pass booths.
Traffic is a bit better on the lower level, but the upper level has better views. Oh, you will have to pay a toll, $15, but it is one-way. It is free to drive into NJ, but you have to pay to leave. If you plan to walk or bike across, the George Washington Bridge is great. You walk up a series of ramps on the Manhattan side, but it is pretty much level on the NJ side. The walkway/bikeway is on the southern side of the bridge, so there are some great views of Manhattan, the Hudson River, and New Jersey.
