What Are New Jersey Highway Sinkholes?
Sinkholes on New Jersey highways are depressions or collapses in the road surface caused by underground erosion. They can range from small cracks to large holes that disrupt traffic and damage vehicles. The New Jersey Department of Transportation monitors reported sinkholes along state routes and interstates.
Common Causes of Sinkholes on NJ Highways
Heavy rain, flooding, and aging drainage systems can weaken soil under roadways. Leaking water mains and natural karst geology also contribute to sinkhole formation. In some cases, construction or utility work destabilizes the ground, leading to sudden collapses on highways.
Where and When Sinkholes Appear
Sinkholes have appeared on major corridors such as the NJ Turnpike, Route 1, and Route 9, often after storms or prolonged wet weather. Reports are most common in central and northern New Jersey, though they can occur in other areas with vulnerable soil conditions.
What Drivers Should Do
If you see a sinkhole on a highway, slow down, change lanes safely, and report it to local authorities or the NJ Turnpike Authority. Avoid driving through standing water near the hole.
