For non Staten Island residents the toll is $12 if you have EZ pass. Without EZ pass the toll is $19. Staten Island residents pay between $6.88 and a little over $7 depending on how many trips per month you make. This is a round trip toll and is collected in only one direction, I believe going into Staten Island.
