Deer Park Avenue and the Babylon–Northport Expressway History

Deer Park Avenue and the Babylon–Northport Expressway History

The evolution of transportation infrastructure on Long Island is often marked by ambitious plans and shifting jurisdictions. One of the most notable examples is the history of Deer Park Avenue and the proposed Babylon–Northport Expressway, a project that aimed to redefine north-south travel across the region but was ultimately curtailed by local opposition.

The Origins of Deer Park Avenue

The roadway known today as Deer Park Avenue and Deer Park Road began its official journey on February 24, 1930, when the County of Suffolk designated the entire stretch as County Road 35 (CR 35). For decades, this route served as a primary artery, but as traffic increased, the need for modernization became apparent.

In 1961, Governor Nelson Rockefeller announced a funding allocation for the reconstruction and widening of Deer Park Avenue. This initiative was designed to address two critical issues: severe traffic congestion during weekend travel and daily commutes in the southern section, and chronic flooding. To combat the drainage problems that occurred even during light rainfall, engineers planned a comprehensive system of drainage pipes beneath the roadway.

The Vision for the Babylon–Northport Expressway

During the 1960s, planners envisioned a massive upgrade to the region's transit capacity. The Babylon–Northport Expressway was intended to be a limited-access expressway—a highway designed for high-speed traffic with controlled entry and exit points—spanning most of Long Island's width.

The proposed route was set to run from NY 27A in the Incorporated Village of Babylon at the southern terminus to the intersection of Elwood Road, Fort Salonga Road (NY 25A), and Reservoir Avenue in the Incorporated Village of Northport at the northern end. The plan included strategic exits at Jericho Turnpike (NY 25) and North Hempstead Turnpike (now Fort Salonga Road, NY 25A), with a potential interchange at Pulaski Road (CR 11).

Project Cancellation and Legacy

Despite the grand scale of the plan, strong local opposition eventually led to the project's cancellation. Only a small 2-mile stretch of the expressway was ever completed. However, the state had already made significant preparations; New York State acquired approximately 40 percent of the properties along the proposed right-of-way, including several parcels along CR 10 (Elwood Road) in Greenlawn and Elwood.

Infrastructure Expansion and Route Realignment

In 1962, the New York State Department of Public Works detailed a plan to widen a 14-mile stretch of Deer Park Avenue between Montauk Highway and NY 25A. This project aimed to transform the road from a two-lane boulevard into a four-lane boulevard at an estimated cost of $20 million (1962 USD), with a target completion date of 1970.

  • First Section: Contracted on May 3, 1962, for $2.4 million, covering the area between Lake Avenue in Deer Park and the Southern State Parkway. This was completed by mid-1965.
  • Second Section: Started in the spring of 1963, covering the 2-mile stretch from Montauk Highway to the Southern State Parkway, also completed by mid-1965.

As part of these changes, the portion of CR 35 between the Northern and Southern State Parkways was transferred to New York State and redesignated as NY 231. While NY 231 originally followed Deer Park Avenue (now CR 34) south to Babylon, it was realigned around 1969 to utilize the completed 2-mile limited-access segment of the Babylon–Northport Expressway.

Frequently Asked Questions

Why was the Babylon–Northport Expressway cancelled?

The project was cancelled primarily due to local opposition, which prevented the state from building beyond the initial 2-mile completed stretch.

What was the purpose of the 1961 reconstruction of Deer Park Avenue?

The reconstruction aimed to reduce traffic congestion during commutes and weekends and to resolve significant flooding issues through the installation of underground drainage pipes.

How did the designation of NY 231 change over time?

NY 231 originally followed Deer Park Avenue south to NY 27A in Babylon, but it was realigned around 1969 to follow the limited-access section of the Babylon–Northport Expressway.

How much of the proposed expressway land did the state acquire?

New York State acquired approximately 40 percent of the properties along the proposed right-of-way, including land in Elwood and Greenlawn.

Where does the Babylon-Northport Expressway end today?

It currently ends at an at-grade intersection with Hunter Avenue, located three-quarters of a mile north of Sunrise Highway.
