What Happened
The New York State Department of Transportation is warning drivers of significant overnight lane restrictions on one of Long Island’s busiest corridors, according to a travel advisory published July 10, 2026. Beginning Sunday night, July 12, two eastbound lanes on Sunrise Highway (State Route 27) will be closed each night as crews carry out a pavement renewal project spanning the Nassau-Suffolk county line.
The closure zone runs from the Wantagh State Parkway in the Town of Hempstead, Nassau County, east to County Line Road — also designated Suffolk County Route 1 — in the Town of Babylon, Suffolk County. That stretch crosses some of the most heavily traveled ground on NY 27, connecting commuter communities on the South Shore with points east toward the Hamptons and Montauk. Per the LongIsland.com report, the restrictions will be in effect Sunday nights through Thursday nights only, from 10 p.m. to 6 a.m., preserving full traffic flow on weekends and during daytime hours.
The project is expected to last approximately four weeks. The NYSDOT emphasized that all construction activities are weather-dependent and subject to change based on conditions — meaning individual closure nights could be canceled or rescheduled if conditions are unfavorable. The agency did not specify which weather thresholds would trigger a delay.
The NYSDOT urged motorists to slow down and move over for highway workers throughout the duration of the project, echoing the department’s standing safety message: “Lives are on the line.” Drivers seeking real-time updates are directed to call 511, visit www.511NY.org, or download the free 511NY mobile app. The agency also maintains active accounts on Facebook, X (formerly Twitter) — including a dedicated Long Island region account — and Instagram.
Location & Road Context
The affected segment of Sunrise Highway sits in the heart of Nassau County’s South Shore and crosses into western Suffolk County, linking the Town of Hempstead with the Town of Babylon. The Wantagh State Parkway interchange is a major transfer point for drivers moving between the parkway system and the Route 27 corridor, making even partial lane reductions during late-night hours consequential for overnight commuters, shift workers, and long-haul drivers heading east.
Our incident database logs 930 recorded incidents on NY 27, including five separate construction entries on July 10, 2026 alone — underscoring that this highway is no stranger to active work zones. Nassau County as a whole accounts for 800 recorded accidents in our local database, reflecting the volume of traffic that moves through this corridor daily.
Broader Impact
The timing of this project — launching the same week a Bay Shore son and father pleaded guilty in a fatal Sunrise Highway DWI crash — puts a sharp focus on driver behavior in active work zones along this corridor. New York State law mandates reduced speeds and increased fines in designated work zones, and the NYSDOT’s own advisory language — “Lives are on the line; slow down and move over for highway workers” — reflects the real danger crews face during overnight lane shifts on a road with this volume of traffic and incident history.
