Stewart Ave. in Garden City appears to be directly south of where the Motor Parkway (in blue) once was. Today, the area north of Stewart Ave., and east of the Roosevelt Field shopping mall is home to a number of buildings, some offices and some light industry. The wooded area behind these buildings (stretching to the Meadowbrook Parkway on its north) is overgrown with weeds and wild flowers (and thorn bushes) and is not very easy to navigate through. Some relics from the Motor Parkway still survive as shown below. The map that follows shows roughly the area I'm talking about. Comparing that with this map, you can pick out the Long Island Rail Road Central line tracks that this map still shows and Stewart Avenue.
