 GEOG: The car chase scenes between Richard Lynch (I) (qv) and  Roy Scheider (qv) take place on both the Palisades Interstate  Parkway and Taconic State Parkway. These roads are on two differnt  sides of the Hudson River, and getting from one road to the other  requires crossing the river a second time via The Tappan Zee Bridge,  which they failed to do.
