What Happened
The Suffolk County Police Department’s First Precinct is advising motorists to expect temporary road closures and heavy traffic congestion due to a series of community events running from Wednesday, August 12 through Sunday, August 16, 2026, according to a report published August 11 by LongIsland.com. The affected communities — Babylon, Copiague, Lindenhurst, and Wyandanch — all fall within the First Precinct’s jurisdiction in southwestern Suffolk County. Drivers moving through any of these areas on the affected dates should anticipate delays and consider alternate routes.
The busiest single day for traffic disruptions will be Saturday, August 15, when four separate events are scheduled across Lindenhurst and Wyandanch simultaneously. In Lindenhurst, a Farmers Market runs from 10:00 AM to 2:00 PM on East Hoffman Avenue, the Belfast Gastro Pub Block Party occupies West Hoffman Avenue from 4:00 PM to 8:00 PM, and the Summer Concert Series takes over Village Square from 7:30 PM to 10:00 PM. Simultaneously in Wyandanch, a Summer Concert Series is scheduled at Wyandanch Plaza from 7:00 PM to 10:00 PM. All four are outdoor events flagged for possible traffic congestion, per the SCPD advisory as reported by LongIsland.com.
The event carrying the most significant road impact is Wednesday on Wellwood in Lindenhurst, scheduled for Wednesday, August 12, from 5:00 PM to 9:00 PM. Unlike most other events on the list — which carry only a congestion advisory — this outdoor event comes with confirmed road closures along Wellwood Avenue from John Street to Gates Avenue, as well as on Hoffman Avenue and at Square Park. Organizers have set a rain date of August 19, 2026 if the event is postponed. Motorists who regularly use Wellwood Avenue as a north-south corridor through the village should plan around the 5:00 PM closure start, which coincides with the evening commute window.
Also on Wednesday, August 12, the Tanner Park Summer Concert Series in Copiague runs from 7:00 PM to 10:00 PM at Tanner Park. The SCPD lists possible traffic congestion for that event, though no road closures are specified. Drivers accessing Tanner Park Road or the surrounding waterfront area that evening should expect elevated volume.
Friday, August 14 brings two concurrent events. Babylon village hosts a Summer Concert at the Village Gazebo from 8:00 PM to 10:00 PM, while Lindenhurst holds the first of its back-to-back weekend installments of the Summer Concert Series at Village Square, running 7:30 PM to 10:00 PM. Both are outdoor events with possible congestion noted, and both fall on a Friday evening when baseline traffic volumes are already elevated heading into the weekend.
The week closes on Sunday, August 16 with Babylon’s Farmers Market at the Gazebo, operating from 8:00 AM to 1:00 PM. While a morning farmers market typically draws lighter vehicle traffic than an evening concert, the SCPD still flagged possible congestion for the Gazebo area during those hours, according to LongIsland.com’s coverage of the First Precinct announcement.
Location & Road Context
The affected areas are concentrated in the First Precinct’s southwestern Suffolk territory. Lindenhurst sees the heaviest event load, with Wellwood Avenue, East Hoffman Avenue, West Hoffman Avenue, and Village Square all implicated across three days. The Wellwood Avenue corridor is a primary north-south connector between Sunrise Highway (NY-27) and Montauk Highway, and any closures there during weekday evening hours have an outsized ripple effect on surrounding local roads. Tanner Park in Copiague sits along the Great South Bay waterfront off Tanner Park Road, where parking access is already constrained on warm summer evenings. Wyandanch Plaza and the Babylon Village Gazebo area are similarly compact commercial hubs where even moderate event crowds can back up nearby intersections.
Broader Impact
With four distinct events converging on the afternoon and evening of Saturday, August 15 — two of them in Lindenhurst alone on Hoffman Avenue, just hours apart — drivers should note that the Hoffman Avenue area could remain congested nearly continuously from 10:00 AM through 10:00 PM that day. Residents and commuters passing through any of these Suffolk County communities mid-week through the weekend are encouraged to check 511NY for real-time conditions and to allow extra travel time, particularly during the Wellwood Avenue closure window on Wednesday evening.
