The above map from a Queen's - Nassau Hagstrom Atlas shows the Motor Parkway crossing east into Nassau County from Queens. The Parkway ran north near Lake Success, crossing the Northern State Parkway and turning east across Lakeville Road, bordering the Phipps Estate to the north. Today, the estate is the Great Neck School Complex housing middle and high schools and admininstrative buildings. The Motor Parkway is obvious today as the roadway leading from a fence on Lakeville Road, south of the school entrance, east towards the athletic fields. Photos were taken in Feb., 2006. The first pictures below show a post almost completely buried on the northern part of the current road (right past the entrance to the Parwkay as shown on the map). Another shot shows the view east and west on the road, with other pictures showing a series of posts that were found about 50 yards past the athletic fields, on the south side of the roadway. The roadway extended east until it crossed the Northern State once again - the last two pictures show what might be part of the bridge abutment and a piece of original roadway. Won't say they are, but worth further investigation.
