What Happened
The New York State Department of Transportation is advising all motorists that westbound Sunrise Highway — State Route 27 — will be fully closed overnight on Monday, July 20, 2026, between 10 p.m. and 5 a.m., to allow crews to perform pavement repairs along the corridor. The closure spans from Exit 53 (State Route 112) in the Town of Brookhaven to Exit 51 (Nicolls Road/County Route 97) in the Town of Islip, covering approximately 3½ miles of one of Long Island’s most heavily traveled east-west arteries.
According to the advisory published July 17 on LongIsland.com, westbound drivers who encounter the closure will be detoured onto the North Service Road for the full 3½-mile span before being permitted to re-enter Sunrise Highway. No alternate westbound highway detour is specified — the North Service Road is the sole designated route through the affected zone.
The NYSDOT issued the travel advisory two days ahead of the scheduled closure, giving commuters and freight operators ample notice to plan around the 10 p.m.–5 a.m. window. The agency stressed that lives are on the line during active highway work, urging motorists to slow down and move over for highway workers — a reminder that carries heightened urgency on a corridor as busy as Route 27. Per LongIsland.com’s report, no additional lane restrictions or secondary closures were announced in connection with this work.
For real-time updates the night of the closure, the NYSDOT directs drivers to call 511, visit www.511NY.org, or download the free 511NY mobile app. The agency can also be followed on Facebook, X (formerly Twitter) — both the main NYSDOT account and the Long Island regional account — and Instagram.
Location & Road Context
The affected segment runs through the central-southern spine of Suffolk County, connecting the Brookhaven–Islip town boundary along Sunrise Highway — a Suffolk County corridor our database links to 1,033 recorded incidents. Exit 53 at State Route 112 in Brookhaven is a major interchange serving Medford and Coram, while Exit 51 at Nicolls Road (County Route 97) in Islip funnels significant volume to and from the Stony Brook and Ronkonkoma areas. Overnight traffic on this stretch, while lighter than daytime volumes, still includes freight trucks, service workers, and late-night commuters traveling between the East End and points west.
The construction activity on NY 27 is part of ongoing pavement maintenance across the region; our database shows multiple concurrent Route 27 construction entries dated July 17, 2026, indicating active work across several segments of the highway this week.
