About William Floyd Parkway

William Floyd Parkway is Suffolk County Route 46 (CR 46), a county road in the Town of Brookhaven. The name says “parkway”, but it is not one of the New York State parkways. Of the 27 federal fatal-crash records on the road that name an owning agency, 25 list the county highway agency and 2 a town highway agency (NHTSA FARS, 2010–2024).

Interchanges with the expressways

  • Long Island Expressway, Exit 68. LIT’s LIE exit list, checked against the NYSDOT I-495 exit list, signs it as “CR 46 (William Floyd Parkway)” in the Shirley / Yaphank area.
  • Sunrise Highway, Exit 58. 511NY’s own records label the exit “William Floyd Parkway” (Town of Brookhaven).

511NY records at either interchange carry the exit number and are filed under the LIE or Sunrise Highway, not under William Floyd Parkway, so those hubs are the place to look for interchange incidents.

Cross streets in the federal record

Police-reported cross streets on FARS fatal crashes on the parkway include Roberts Road (3 crashes), Dawn Drive (2), Montauk Highway, Mastic Boulevard, Victory Avenue and Yaphank Woods Boulevard (1 each), NHTSA FARS 2010–2024.

Where the federal record places its fatal crashes

All 37 FARS fatal crashes on William Floyd Parkway from 2010 through 2024 fall inside the Town of Brookhaven. By 2020 Census place, 27 were in Shirley, 7 in Ridge, 1 in Yaphank and 1 in East Shoreham (NHTSA FARS, placed by the reported crash coordinates). The full breakdown by year, time of day and road user is in the federal-record section above.

What this page can and cannot show

  • Live 511NY conditions. 511NY rarely lists William Floyd Parkway as an event’s road. In the 90-day window LIT exported on Oct. 27, 2026, it listed none as a crash. An empty live section therefore means 511NY has nothing posted, not that the road is clear.
  • LIT incident reports. The reports list shows Long Island Traffic articles tagged to this road. Some earlier William Floyd Parkway stories were published without a road tag and do not appear there yet; the recent coverage below links to them directly.
  • Federal fatal-crash record. NHTSA FARS, 2010–2024, matched to this road by the road name or route number police recorded. 2024 is preliminary.
