Lemoine Avenue is heavy with commercial development in the Coytesville section of Fort Lee, but as the road runs into Englewood Cliffs it transitions to corporate office buildings, and into the affluent community of Alpine in the state's northeastern corner, it becomes more residential. Near Norwood, just south of the state line, US 9W crosses under the parkway and enters New York. Before the construction of the PIP, US 9W used to follow a route through the State Line Lookout at the New Jersey–New York border which is now accessible only from the parkway.
