Much of the unbuilt parkway's right-of-way has since been transformed into parks with trails and other recreational amenities.

It also required the condemning of a Standard Oil Company tank farm to avoid demolishing high-priced homes, which were to be taken via the three alternate routes proposed.

With this new interchange, the traffic circle with Plainview Road in Bethpage State Park would be eliminated.
