A large brush fire near the New Jersey Turnpike in Union County caused significant delays for commuters Tuesday evening. The fire comes during the peak of wildfire season.

Crews were out for hours near the Turnpike in Elizabeth to keep the fire under control. The fire was also close to Newark Liberty International Airport.

The fire sent large plumes of black smoke into the air. The smoke and flames threatened several nearby businesses and commuters. Luckily, no flights at Newark Liberty were impacted.

The fire comes on the heels of the New Jersey Forest Fire Service performing prescribed burns across the state to prevent wildfires from developing. New Jersey saw many large wildfires last year.

Officials say a car fire may have potentially been the cause of Tuesday’s fire. But this point has not been officially confirmed.

No injuries were reported.
