Road names as recorded by police and normalised to common Long Island names.

When and where

  • Of the 4 crashes with a recorded time, 0 happened between 8 p.m. and 6 a.m., 0 between 4 and 8 p.m., 2 between 10 a.m. and 4 p.m., and 2 between 6 and 10 a.m.
  • 0% happened in darkness.
  • 0 of the 4 deaths were on expressways or parkways; 4 were on arterials and local streets.

Who owns the roads where they happened (2015–2024)

FARS has recorded the owner of the roadway since 2015. Of the 3 fatal crashes in Bayport since then:

  • Town roads 2 (67%)
  • State highways 1 (33%)

Ownership matters in New York because claims against a county, town, city or village generally require a notice of claim within 90 days (General Municipal Law § 50-e), while claims against the State are brought in the Court of Claims under Court of Claims Act § 10. This is general information, not legal advice.

Rate: 3.1 traffic deaths per 100,000 residents per year, against 9.1 for Suffolk County. This is a resident-based rate, not a measure of how risky the roads are to drive: crashes are counted where they happen, not where the people involved live, so a small community crossed by a major highway shows a high rate. With 8,609 residents, a single crash moves Bayport's rate substantially.

All reported crashes in the Town of Islip, 2021–2024

New York's crash file codes each crash to a town, city or village — never to a hamlet — so the finest official count that covers Bayport is for the Town of Islip, which contains it. Police reported 35,004 crashes there from 2021 through 2024 — about 24 a day. 10,222 (29.2%) injured someone and 128 were fatal. [D]

Notable facts about Bayport

  • Bayport was part of the roughly 50,000-acre patent William Nicoll purchased from Sachem Winnequaheagh of Connetquot on November 29, 1683, which he named Islip Grange.[2]
  • New York State barred any oyster from being sold under the name "Bluepoint" unless it came from the Great South Bay, by a law passed in 1908.[5]
  • By 1900 the Blue Point Oyster Company was shipping as many as 100,000 barrels of Great South Bay oysters a year around the world.[4]
  • Bayport's grass airfield, Davis Field (also known as Bayport Aerodrome), was added to the National Register of Historic Places on January 22, 2008.[15]
  • The overpass where NY 454 (Veterans Memorial Highway) meets NY 27 (Sunrise Highway) at Bayport is officially designated New York's "POW-MIA Bridge."[12]
  • Suffolk County's own road inventory shows that Montauk Highway through Bayport is a county road, County Road 85, not a state highway.[14]
  • The Town of Islip's prior-written-notice law, Code § 47A-3, which shields the Town from most road-defect lawsuits, has been in effect since October 3, 1978.[9]

History

Bayport lies within the Town of Islip, whose Native inhabitants before European settlement were, according to the Town's own history, "a sub-division of the Algonquins known as the Secatogues," who occupied the whole of what is now the Town.[1] On November 29, 1683, William Nicoll became the Town's first colonial patentee, purchasing roughly 50,000 acres from Sachem (Chief) Winnequaheagh of Connetquot and naming his plantation Islip Grange, after Islip, England.[2]

Islip's location on the Great South Bay made fishing and shellfishing central to the local economy from the nineteenth century on.[1]

A local library serving Bayport traces to 1938, when it "began as a Blue Point P.T.A. project" with a collection of donated books.[21] It took its present joint name in 1952, "when the Bayport and Blue Point school districts joined forces," and moved into a new building in 1957.[22][23] A local nonprofit, the Bayport Heritage Association, is listed by the Town of Islip as one of its historical societies, with an address of PO Box 4, Bayport, NY 11705.[8]

In the twentieth century Bayport became home to a grass airfield, later listed on the National Register of Historic Places as "Davis Field" (also known as Bayport Aerodrome), designated January 22, 2008 under reference number 07001456.[15] The National Park Service's own asset record for the listing gives its resource type as a historic "District," names Curtis Davis, Sr. as its architect, lists "TRANSPORTATION," "COMMUNITY PLANNING AND DEVELOPMENT" and "ARCHITECTURE" as its areas of significance, and gives periods of significance of 1925-1949 and 1950-1974 with 1945 as its single most significant year.[15]

How the roads got here

New York State's own route-reference document places Bayport at a specific highway junction: the overpass carrying NY 454 (Veterans Memorial Highway) over NY 27 (Sunrise Highway) is officially named the "POW-MIA Bridge," described there as "NY 454/Veterans' Memorial Highway: crosses NY 27 (Sunrise Highway) at Bayport."[12] The same document traces NY 454 south from NY 25 through "Commack, Hauppauge, west of Patchogue (NY 27)," meaning the highway's southern end sits at this Bayport-area interchange with Sunrise Highway.[13]

Montauk Highway through Bayport is not a state road. Suffolk County's own official road inventory lists this stretch as County Road 85, running from "NYS RT 27, Sunrise Hwy to ~320' w/o West Ave" near the Village of Patchogue.[14] By contrast, the state's touring-route description of the older alignment, NY 27A, ends its signed run several hamlets to the west, following "Merrick Road and Montauk Highway to Babylon, Bay Shore, Islip, East Islip, Great River, Oakdale Exit (NY 27)" — it does not continue through Bayport.[11]

Law and legal history

Like most Long Island municipalities, the Town of Islip has enacted a prior written notice law limiting its liability for defective roads and sidewalks, applicable Town-wide, including in Bayport. Section 47A-3 of the Code of the Town of Islip, "Liability of Town," added October 3, 1978 and amended August 21, 1984 and December 17, 1985, provides that "No civil action shall be maintained against the Town of Islip or any of its employees for damages or injuries to persons or property" arising from a defective highway, street, bridge, culvert, sidewalk or similar Town-owned property, or from snow or ice on one, unless written notice was actually given to the Town Clerk or the Commissioner of Public Works and the Town failed to repair the condition within a reasonable time.[9]

The Appellate Division, Second Department, has enforced this law against Town of Islip plaintiffs. In Cruzate v. Town of Islip, 162 A.D.3d 853 (2d Dept. 2018), the court affirmed summary judgment for the Town after a driver was injured when his car struck a raised drainage cover; the court held that "a municipality that has adopted a prior written notice law cannot be held liable for a defect within the scope of the law absent the requisite written notice," and found that the Town had shown, through Town Clerk and Department of Public Works records, that it had received no such notice of the defect.[10] The Cruzate decision cites an earlier case for the same burden-shifting rule, Factor v. Town of Islip, 134 A.D.3d 984 (2d Dept. 2015): once the Town shows a lack of prior written notice, the burden shifts to the plaintiff to show that the Town either created the hazard or received a special benefit from it.[10]

Cases of record

Cruzate v. Town of Islip, 162 A.D.3d 853, 2018 NY Slip Op 04531 (2d Dept 2018)[10]
New York Supreme Court, Appellate Division, Second Department, 2018. Applies the Town of Islip's prior written notice law (Code § 47A-3), which governs road- and sidewalk-defect claims Town-wide, including in Bayport; no source found ties the underlying accident itself to Bayport.Affirmed summary judgment for the Town: a municipality with a prior written notice law cannot be held liable for a covered defect absent the requisite notice, and the Town established through Town Clerk and Department of Public Works records that it received none; the plaintiffs raised no triable issue as to notice or to the affirmative-creation/special-use exceptions.

Each summary describes the cited decision only. Later appellate history is noted where we found it, but it has not been checked systematically — confirm a case's current status with a citator before relying on it. General information, not legal advice.

Government, courts and policing

Bayport has no government of its own; it is an unincorporated hamlet of the Town of Islip.[3] Policing is provided by the Suffolk County Police Department's Fifth Precinct, headquartered at 125 Waverly Avenue in Patchogue, which by its own description "renders patrol and other police service to the southern portion of Brookhaven Town, the eastern portion of Islip Town, and the incorporated villages of Patchogue and Bellport" — the description covering Bayport, which sits in the eastern part of the Town between Sayville and Blue Point.[16][18] By contrast, the Third Precinct, headquartered in Bay Shore, describes its own coverage area as "the hamlets of Bay Shore, Baywood, Brentwood, Brightwaters, Islip, Central Islip, East Islip, West Islip, and Islip Terrace" — all in the western part of the Town, and none of them Bayport.[17]

Railroad and transit

The original Long Island Rail Road line reached the Town of Islip in 1844, but that line ran inland, north of the bay hamlets.[7]
