Hello all I need to go to Tappan NY RT 303 with a Commercial Van and i was told that after i go over the GWB coming from Long island I will see an exit for Palisades Pkwy the next exit i believe is exit 73-would take me to 9W which i can take to a road called OAT TREE RD which will take me to RT 303 right where i need to go.. My question is are the directions correct? Thanks so much!! Mark
