New York State Route 231 (NY 231) is a north–south state highway located in Suffolk County, New York, in the United States. The route extends for 9.05 miles (14.56 km) from a partial interchange with NY 27A in Babylon to an interchange with the Northern State Parkway in Dix Hills. The southernmost 2 miles (3.2 km) of NY 231 is a limited-access highway known as the Babylon–Northport Expressway; the remainder of NY 231 is known as Deer Park Avenue. As the name suggests, the Babylon-Northport Expressway was originally intended to be a north-south expressway spanning most of the width of Long Island from Babylon to the southern edge of Northport village. However, local opposition to the expressway eventually resulted in the cancellation of the project before anything more than the existing 2 mile stretch could be constructed.[4]

Route description[edit]

NY 231 northbound at the Southern State Parkway in North Babylon

NY 231 begins at an interchange with NY 27A (Montauk Highway) in Babylon. The route progresses northward around Hawleys Lake as a four-lane freeway. A short distance after NY 27A, NY 231 meets ramps from County Route 50 (CR 50, named John Street), but does provide service to the county road from either direction. After John Street, the freeway crosses over the Long Island Rail Road's Babylon Branch and crosses northward through a large residential district. After paralleling Madison Street in North Babylon, NY 231 intersects with NY 27 (the Sunrise Highway) in a full cloverleaf interchange. From NY 27, NY 231 heads northward and northwestward, intersecting with Hunter Avenue in North Babylon, where the freeway portion ends and the highway becomes an arterial boulevard. The route curves back to the north through the large commercial district, interchanging with CR 34 (Deer Park Avenue). Right after the interchange, NY 231 interchanges with the Southern State Parkway at a full cloverleaf in North Babylon.[5]

After the Southern State Parkway, NY 231 continues northward as an arterial boulevard named Deer Park Avenue. The surroundings are mostly commercial, continuing as a four-lane road and intersecting with CR 4 (Commack Road) at a fork. After Commack Road, NY 231 becomes a residential arterial with a grassy, divided median and intersecting with CR 57 (Bay Shore Road) in Deer Park. The highway continues northward through Deer Park, crossing through a large commercial strip and under another Long Island Rail Road line. There is a short interchange with Long Island Avenue in Deer Park as NY 231 continues into Dix Hills, where it becomes residential once again near the intersection with CR 2 (Straight Path).[5]

The arterial remains residential, continuing northward into an interchange with Interstate 495 (I-495, named the Long Island Expressway) in Dix Hills. Here, the road expands to five lanes and crosses under the interstate, where NY 231 becomes four lanes once again. The highway continues northward along the residential strip, intersecting with CR 67 (the Long Island Motor Parkway). Further north, NY 231 enters a partial cloverleaf interchange with the Northern State Parkway, where the designation terminates. The highway forks, continuing northwest as CR 35 (Deer Park Road, and later, Park Avenue), and northeast as CR 66 (East Deer Park Road).[5]


The entirety of Deer Park Avenue and Deer Park Road was originally designated as part of CR 35 on February 24, 1930.[1]

Governor of New York Nelson Rockefeller announced in 1961 funding would let to start reconstruction and widening of Deer Park Avenue.[6] The project would help reduce congestion along the southern section of Deer Park Avenue during commutes and travel on weekends. The project would also help the ability to reduce flooding along Deer Park Avenue, which was significant even during the lightest rains. To relieve this, a system of drainage would be constructed underneath Deer Park.[7]

In 1962, the New York State Department of Public Works announced that Deer Park Avenue would be widened for a fourteen-mile stretch from Montauk Highway and NY 25A. The road would be expanded from a two-lane boulevard to a four-lane boulevard, at a cost of about $20 million (1962 USD) with a slated completion of 1970. The first section would have its contract let on May 3, 1962, with a cost of $2.4 million. This stretch would include the piece between the Southern State Parkway and Lake Avenue in Deer Park. The new piece of the right-of-way would be completed by the middle of 1965, in which a new road would be constructed from the Montauk Highway to the Southern State.[7]

In the 1960s, the portion of CR 35 between the Southern and Northern State Parkways was transferred to the state of New York,[1] which designated the highway as NY 231.[2] Initially, NY 231 followed Deer Park Avenue (now CR 34) south to NY 27A in Babylon;[8] however, it was realigned c. 1969 to follow a 2-mile (3.2 km) section of the new Babylon–Northport Expressway.[8][9]

Hot Rod Mecca[edit]

For at least 30 years, Deer Park Avenue served as one of the nation's hottest cruising strips.[10] The New York Times twice called the three-mile stretch from North Babylon to Deer Park, New York a "Mecca for young people" where crowds of teens and young adults, usually those below legal drinking age, from Long Island and Queens, would line parking lots, hoods up, chatting and showing off their rides. On June 4, 2001 at 7:30 p.m., partly due to a second feature in The New York Times, the Joint Civic and Taxpayers Association met with elected town and New York State Department of Transportation officials for an action plan to crack-down on the drag-racing, littering and cruising calling it a significant quality of life issue for community residents.[11]
