Caumsett Parkway: The History of a Proposed Long Island Roadway
The story of the Caumsett Parkway is a fascinating example of mid-century urban planning and the subsequent shift toward environmental conservation. Originally conceived as a scenic artery to connect the heart of Long Island to its northern shores, the project evolved from a grand highway proposal into the foundation for modern recreational green spaces.
The Vision of the Long Island State Park Commission
On May 20, 1961, the Long Island State Park Commission (LISPC) proposed a new parkway designed to link the Northern State Parkway with the proposed Caumsett State Park, a site featuring an arboretum and wildlife refuge. The plan envisioned the parkway as a northern extension of the Bethpage State Parkway, utilizing filled land to cross Cold Spring Harbor.
To avoid the demolition of expensive residential properties, the LISPC sought to condemn a tank farm owned by the Standard Oil Company. By 1965, the commission proposed a four-lane parkway that would wind through Cold Spring Harbor and enter the village of Lloyd Harbor. However, by 1968, the vision shifted toward a more modest, landscaped two-lane road.
This shift in planning met with resistance from conservationists associated with the Caumsett estate. These advocates argued that the plans remained too vague and expressed concerns that Caumsett should not be transformed into a high-traffic facility similar to Jones Beach State Park on the southern shore.
Proposed Infrastructure and Interchanges
The realization of the Caumsett Parkway required the northward extension of the Bethpage Parkway, which involved the planning of four new interchanges. These proposed junctions were designed to streamline traffic and eliminate existing bottlenecks, such as the traffic circle with Plainview Road in Bethpage State Park.
- Exit B5: A junction at NY 135 (Seaford–Oyster Bay Expressway).
- Plainview Avenue: A diamond interchange serving Bethpage State Park.
- Old Country Road: A full cloverleaf interchange.
- Long Island Expressway: A partial cloverleaf interchange with NY 495.
Further north, the plan included a full cloverleaf interchange with the Northern State Parkway, a diamond interchange with NY 25 (Jericho Turnpike), and a final interchange with NY 25A and NY 108. From there, the road would have followed the east coast of Cold Spring Harbor, curved inland through Lloyd Harbor, and terminated at a traffic circle at the southern end of Caumsett State Park.
From Highway to Heritage: The Legacy of the Right-of-Way
Although the parkway was never built, the right-of-way (the legal right to pass through grounds or property) acquired in the 1960s remained. Over time, these strips of land were repurposed for public benefit rather than automotive transport.
In 1987, the Long Island Greenbelt Trail Conference suggested that the unused land be integrated into a new Greenbelt trail. This vision was realized in September 2002, when Governor George Pataki announced the opening of Trail View State Park. This linear state park spans 400 acres (160 ha) and utilizes the rights-of-way originally intended for the Caumsett and Bethpage Parkway extensions, featuring a 7.4-mile (11.9 km) trail.
Some of the acquired land also contributed to the creation of Cold Spring Harbor State Park.

Frequently Asked Questions
Why was the Caumsett Parkway never completed?
The project faced opposition from conservationists who feared the Caumsett estate would become a high-use facility similar to Jones Beach State Park, and concerns were raised regarding the vagueness of the LISPC's evolving plans.
What happened to the land acquired for the parkway?
The right-of-way was repurposed to create green spaces, including Cold Spring Harbor State Park and the 400-acre Trail View State Park.
What is Trail View State Park?
Opened in 2002, it is a linear state park that utilizes the unbuilt rights-of-way of the Caumsett and Bethpage Parkways, featuring a 7.4-mile trail.
Which existing roads were the parkway intended to connect?
It was designed to connect the Northern State Parkway and the Bethpage State Parkway to the proposed Caumsett State Park.
How did the LISPC plan to avoid demolishing expensive homes?
The commission proposed condemning a Standard Oil Company tank farm to bypass high-priced residential areas.
