Incident location, Long Island
Two lanes of the westbound Long Island Expressway remain closed near Exit 49 after a large sinkhole opened Thursday afternoon, damaging at least two vehicles and creating significant traffic delays for commuters. Suffolk County police say the sinkhole was reported around 1 p.m. in the deceleration lane for Exit 49N (State Route 110) in the Town of Huntington, according to News 12 Long Island.
The sinkhole measures approximately 10 feet in diameter and 8 feet deep, creating a dangerous hazard that caught drivers off guard during the afternoon rush period. Jeffrey Jimenez was among the first motorists to encounter the massive hole, hitting it directly and blowing out both his front tires. Despite his efforts to warn the driver behind him, it was too late – the second vehicle ended up partially trapped in the hole.
“It’s scary. By the grace of God I’m fine. I didn’t get hurt thank God,” Jimenez told News 12. “I’ve never seen anything like that. That’s fatal. Someone could die from something like that.” No injuries have been reported from the incident, according to Suffolk County police.
The New York State Department of Transportation confirmed that the sinkhole appears to have been caused by a contractor working under permit on a local municipal sewage project. DOT crews began emergency work Thursday night to secure the area and install new asphalt pavement, but the right and center lanes of the westbound expressway will remain closed until repairs are completed. The lane closure is expected to last at least 24 hours, police say.
“The New York State Department of Transportation responded this afternoon to a sinkhole on the westbound Long Island Expressway (Interstate 495) in the deceleration lane for Exit 49N (State Route 110) in the Town of Huntington, Suffolk County,” a DOT spokesperson stated. “Work is beginning this evening to secure the area and install new asphalt pavement. While a timeline is not currently available, we are working as expeditiously as we can to fully reopen the Long Island Expressway sometime tomorrow.”
The DOT has advised motorists to use the North Service Road or the Northern State Parkway as alternate routes during the closure. The agency emphasized their appreciation for “the patience of the traveling public” as crews work to restore normal traffic flow on this critical stretch of highway.
Location & Road Context
The sinkhole occurred at Exit 49 for Route 110 in Melville, a heavily traveled section of the Long Island Expressway that serves as a major artery for commuters traveling between Nassau and Suffolk counties. This stretch of the LIE experiences some of the heaviest traffic volumes on Long Island, particularly during peak commuting hours when the incident was first reported.
According to Long Island Traffic records, this section of I-495 has experienced 672 recorded incidents, making it one of the more problematic areas for traffic disruptions. Recent incidents in the area include emergency construction work and ongoing maintenance projects that have periodically affected traffic flow.
Investigation & Legal Proceedings
Te Pei, a civil engineering assistant professor at Stony Brook University, explained that underground pipelines and erosion can create the perfect conditions for this type of collapse. “We need to really look into the subsurface pipeline system and the local geology,” Pei told News 12. “So where it might occur is not certain, but definitely there might be more incidents in the future.”
The repair process for a sinkhole of this magnitude is complex and time-consuming, according to Pei. Crews must excavate the entire area, identify the root cause of the collapse, replace any damaged underground infrastructure, properly backfill the sinkhole, and restore the pavement surface. Without completing all these steps thoroughly, the same area could experience another collapse in the future.
Broader Impact
The timing of this infrastructure failure highlights the ongoing challenges facing Long Island’s aging underground utility systems, particularly as municipal sewage projects and other maintenance work continue throughout the region. The incident occurs as the area is already dealing with potential transportation disruptions from an imminent LIRR strike, potentially forcing more commuters onto already strained roadways. The DOT’s quick response and round-the-clock repair efforts demonstrate the critical importance of maintaining traffic flow on this vital east-west corridor that serves hundreds of thousands of daily commuters.
