About Sunrise Highway
Sunrise Highway — designated New York State Route 27 and known to most Long Islanders simply as “Sunrise” — is the principal arterial of Long Island’s South Shore. Stretching roughly 100 miles from Valley Stream near the Queens border in Nassau County east to Montauk Point at the far tip of the South Fork, it is the South Shore’s workhorse road: commuter route, commercial corridor, and the main truck artery for the towns that the parkways refuse to carry. Where the parallel Southern State Parkway to the north bans commercial traffic and threads through low stone overpasses, Sunrise Highway is a conventional state road open to everything — and that openness shapes both its usefulness and its crash profile.
What makes Sunrise Highway distinctive is that it is really three roads wearing one name. Through Nassau County it behaves like an expressway: a divided, partially grade-separated highway with numbered exits and a 55 mph design speed. Through western and central Suffolk it becomes a signalized commercial arterial lined with retail. And on the East End, past the Shinnecock Canal, it narrows toward a two-lane village road on its way to Montauk. A driver crossing the full corridor experiences three completely different driving environments, and the transitions between them are where many of its problems concentrate.
Origins and construction
Sunrise Highway grew out of a patchwork of early-20th-century South Shore local roads that were stitched together and numbered as a state route in the 1920s and 1930s. As post-war suburbanization filled in Nassau County’s South Shore, the Nassau section was progressively rebuilt into a divided, partially grade-separated arterial — giving it a quasi-expressway character for roughly 20 miles. The eastern reaches were never rebuilt to the same standard; the East End sections remain a conventional surface road, reflecting the lighter development of the South Fork. The result is a corridor whose engineering standard drops, step by step, the farther east you drive.
Route geometry (Valley Stream → Montauk)
From west to east, Sunrise Highway begins in Valley Stream near the Nassau–Queens line and runs through the dense Nassau commercial belt of Lynbrook, Rockville Centre, Baldwin, Freeport, Merrick, Bellmore, and Massapequa. Crossing into Suffolk County, it passes through Amityville, Copiague, Lindenhurst, and Babylon, then on through Bay Shore, Islip, Sayville, and Patchogue. Continuing east it serves Bellport, Brookhaven, Shirley, and the Moriches before reaching the East End, where it carries on through Hampton Bays, Southampton, East Hampton, and Amagansett to its terminus at Montauk. The corridor intersects nearly every major South Shore route, including the Meadowbrook, Wantagh, and Robert Moses parkways, the Southern State Parkway, the Seaford–Oyster Bay Expressway (Route 135), Veterans Memorial Highway, and Nicolls Road (CR 97) in central Suffolk.
Jurisdiction and patrol
Because Sunrise Highway is a surface highway rather than a state-police-patrolled parkway, jurisdiction follows the county and town it runs through. The Nassau County Police Department patrols the Nassau divided-highway section. The Suffolk County Police Department covers the western and central Suffolk segments through its precinct system. On the East End — Southampton and East Hampton towns, which run their own departments — the Southampton Town Police and East Hampton Town Police are the primary responding agencies, as seen in the reporting on the fatal Southampton crash below. NYS Police Troop L assists on the limited-access segments and at major multi-vehicle incidents. The roadway itself is owned and maintained by NYSDOT.
Speed limits
Posted limits change repeatedly along the corridor, tracking its shifting character. The divided, limited-access stretches in Nassau and parts of western Suffolk are posted at 55 mph. The signalized commercial corridors through Valley Stream, Freeport, Babylon, and Bay Shore drop to 40–45 mph. The two-lane East End sections run 40–55 mph depending on village limits. Drivers unfamiliar with the road frequently carry expressway speeds into the slower arterial sections — a recurring factor in rear-end and pedestrian crashes.
Trucks and commercial vehicles
Sunrise Highway is the South Shore’s primary truck route, and this is its single most important operational distinction. The parkways that parallel it — the Southern State, Wantagh, Meadowbrook, and Robert Moses — all ban commercial vehicles and were built with low clearances that physically exclude trucks. That leaves Sunrise Highway (NY-27) as the only continuous South Shore route legal for trucks and buses. The corridor therefore carries a heavier commercial-vehicle mix than the parkways, which raises both crash severity and the frequency of debris and disabled-vehicle events — a dynamic visible in the fatal garbage-truck rollover and the tow-truck-operator fatality documented below.
Dangerous Sections
The following segments are recurring crash and closure locations based on NYSDOT crash patterns and Long Island Traffic’s running corpus of Sunrise Highway incident reports.
Valley Stream / Lynbrook (Nassau County western section): The western end of Sunrise Highway handles enormous commercial traffic generated by the Green Acres Mall and the dense retail strip running east toward Lynbrook and Rockville Centre. Frequent driveway cuts, pedestrian crossings, and turning movements at signalized intersections collide with high-speed through traffic. This is one of the corridor’s highest pedestrian-injury zones.
Freeport commercial corridor: The Freeport stretch carries one of the highest pedestrian crash rates on the entire road. Long stretches between protected crossings, combined with dense retail on both sides and near-highway speeds, produce a persistent pedestrian-safety problem that Nassau County and NYSDOT have repeatedly studied for traffic-calming improvements.
Bay Shore — Exit 44 area (Suffolk County): The approaches to Bay Shore near Exit 44 and Brentwood Road are a documented hot spot, with heavy commercial-truck traffic and a narrow, high-speed shoulder environment. In April 2025 a tow-truck operator working the shoulder near Exit 44 was struck and killed there — see the editorial coverage below. The interchange weaving and roadside-work exposure make this one of the corridor’s most dangerous Suffolk segments.
Central Suffolk — Exits 53 to 56 (Patchogue to North Bellport): The central-Suffolk stretch from around Exit 53 through Exit 56 in North Bellport sees frequent serious crashes and full closures, including a pedestrian-involved closure at Exit 53 and a multi-hour westbound shutdown at Exit 56 near Station Road. Early-morning commute crashes here routinely close lanes for investigation, snarling westbound traffic toward New York City.
East End two-lane sections (Hampton Bays to Montauk): East of the Shinnecock Canal, Sunrise/Montauk Highway narrows to two lanes through Southampton and East Hampton. High summer beach volumes, limited passing opportunities, and dark rural stretches at night produce severe head-on and multi-vehicle collisions — including the fatal five-vehicle Southampton crash detailed below.

Accident Statistics
Sunrise Highway’s crash profile reflects its split personality as both a quasi-expressway and a commercial arterial. Across its Nassau and Suffolk segments the corridor records on the order of several thousand reported crashes annually, with the Nassau County commercial section accounting for a disproportionate share of injury and pedestrian crashes because of its dense, signalized, driveway-heavy design. Rear-end collisions dominate the divided-highway sections where drivers carry expressway speeds into slowing traffic, while pedestrian and bicycle crashes are elevated relative to the parallel Southern State Parkway — a direct consequence of the road’s commercial land use and near-highway speeds. On the East End, the two-lane sections see a higher share of head-on and multi-vehicle crashes, particularly at night and during the summer beach season.
