What Happened
The New York State Department of Transportation will shut down two westbound lanes on Sunrise Highway (State Route 27) on weeknights beginning Tuesday, September 8, 2026, according to a travel advisory published September 3 on LongIsland.com. The closures run each night from 10 p.m. to 6 a.m. and are scheduled to continue for approximately four weeks.
The affected stretch runs from County Line Road (County Road 1) in the Town of Babylon, Suffolk County, westward to the Wantagh State Parkway in the Town of Hempstead, Nassau County. The project spans the Nassau-Suffolk county line. NYSDOT says the closures are to facilitate a pavement renewal project on the westbound roadway.
All construction activities are weather-dependent and subject to change based on field conditions, NYSDOT stated. Drivers on the westbound corridor between 10 p.m. and 6 a.m. on weeknights should plan for reduced lane capacity across the full four-week window. NYSDOT directs motorists to call 511, visit 511NY.org, or use the free 511NY mobile app for real-time updates.
Location & Road Context
The work zone sits on one of Long Island’s busiest east-west arterials, connecting the South Shore communities of Suffolk and Nassau counties. The segment between Babylon and Wantagh carries commuter and commercial traffic that also feeds onto the Wantagh State Parkway interchange at its western terminus.
According to Long Island Traffic’s incident registry, Sunrise Highway has recorded 22 incidents in the past 30 days and 87 so far in 2026, making this one of the corridor’s more active stretches for traffic events. The most recent prior fatal crash on the corridor occurred August 10, 2026. Nearby corridors have also been active this week: a moderate crash was recorded on the Southern State Parkway on September 2, and a minor incident on the Meadowbrook State Parkway on September 3.
Broader Impact
The 10 p.m. to 6 a.m. window captures late-night and early-morning traffic on a road with 87 recorded incidents in 2026 through early September. Westbound drivers approaching the work zone from County Line Road should allow extra time; the closure runs eight hours per night across roughly 20 weeknights. NYSDOT’s advisory notes that highway workers are present and reminds motorists of New York’s Move Over Law.
