What Happened
The New York State Department of Transportation is advising Long Island motorists of imminent overnight lane closures on Veterans Memorial Highway in the Town of Islip, according to a travel advisory reported by LongIsland.com on July 21, 2026. Both directions of State Route 454 — Veterans Memorial Highway — will be subject to closure beginning Wednesday, July 22, with closures running weeknights between 10 p.m. and 6 a.m. for approximately five weeks.
The affected stretch runs between Wheeler Road (State Route 111) and the Long Island Expressway (Interstate 495) North Service Road. The purpose of the closures is to facilitate an asphalt pavement resurfacing project along this corridor in Suffolk County. Construction activities are weather-dependent and subject to change based on conditions, NYSDOT noted.
Drivers traveling eastbound during closures will be detoured onto southbound Wheeler Road, then directed to the Long Island Expressway South Service Road to regain access to Veterans Memorial Highway. Those traveling westbound during closures will be rerouted onto the Long Island Expressway North Service Road and then northbound Wheeler Road to reach Veterans Memorial Highway. Electronic message signs installed near the work zone will display additional real-time closure information for motorists approaching the area.
For up-to-date travel conditions, the NYSDOT advises drivers to call 511, visit 511NY.org, or download the free 511NY mobile app. The department also reminded drivers that lives are on the line in active work zones, urging motorists to slow down and move over for highway workers.
Location & Road Context
Veterans Memorial Highway (State Route 454) is a major east-west arterial in the Town of Islip, connecting communities in central Suffolk County and providing critical access to the Long Island Expressway interchange at Wheeler Road (State Route 111). This corridor carries significant commuter and commercial traffic between the LIE and surrounding neighborhoods, making overnight closures — rather than daytime shutdowns — the practical choice for minimizing disruption during the resurfacing work.
Our local incident database has recorded 640 accidents in Suffolk County to date, underscoring the importance of clear detour signage and driver awareness whenever major construction projects require lane or road closures along busy routes like Route 454.
Broader Impact
Pavement resurfacing projects of this scale — running for approximately five consecutive weeks of weeknight closures — typically require careful coordination between the NYSDOT and local municipalities to ensure that detour routes along Wheeler Road and the LIE service roads can absorb the diverted traffic without creating secondary congestion points, particularly during the late evening and early morning hours when the closures are active. Drivers using the LIE service roads or Wheeler Road during the five-week window should expect added volume and plan accordingly.
