It seems once you cross the George Washington Bridge anything is possible. Seriously this question needs to be answered by the local building inspector IN WRITING. If you dont mind a question WHY go through this obstruction? Are they planning a finished basement? 7 Nov 2000 at 1:38 pm #299219 fourth yearParticipant I guess George Washington bridge is the boundary between the two parts of the United States. Those two parts being NYC and area of the aborigines. At least that is how NYC people seem to consider anyone who is not them.
