It begins at a trumpet interchange with the Southern State Parkway in North Massapequa and serves Boundary Avenue, NY 24, and Central Avenue before terminating at a traffic circle with Plainview Road and a local park road in Bethpage State Park.

The Bethpage Bikeway, was extended from its original northern terminus to the Long Island Rail Road station in Syosset.

[3] After passing under Boundary Avenue, the Bethpage Parkway bends to the northwest, leaving the Massapequa Preserve but continuing to run across a wooded strip of land in an otherwise heavily developed area.

Continuing northward, the Bethpage State Parkway passes under the Main Line of the Long Island Rail Road tracks and enters Bethpage, where the highway meets Central Avenue at exit B4 just north of the tracks.

Development throughout Nassau County had become common: with a 441% increase in population from 1900 to 1930, it was becoming more urgent to secure open land for parks.

[6] Bethpage State Park was created from land originally owned by Benjamin Yoakum, a railroad executive.

It was made into public land a year later, at which point the property was renamed the Bethpage Golf Club.

Along with these designs, Moses also confirmed that the parkways would remain free of commercial vehicles and truck traffic.

The ceremonial ribbon was cut at noon, after which Moses spoke praise to the federal government for its assistance and discussed how Bethpage State Park was previously inaccessible.

[8] During the opening, Moses was already proposing plans to extend the Bethpage southward to NY 27 and Merrick Road in Massapequa.

The path also continued south to Merrick Road by way of the right-of-way formerly proposed for the Bethpage Parkway's southern extension.

[13] In 1990, the Long Island Regional Planning Board proposed a new parkway extension to NY 25A in Cold Spring Harbor as part of a 20-year highway improvement program.

[17] The New York State Department of Transportation is currently constructing the Bethpage Bikeway, a multi-use trail extending 5.8 miles (9.3 km) northward from Bethpage State Park to the Syosset station on the Long Island Rail Road.

[18] The proposed bike trail will cost $6.49 million (2012 USD) and was expected to be completed on July 3, 2012.
