The site is located under the Pulaski Skyway, which remained closed in both directions Saturday morning. According to the New Jersey’s Department of Transportation, the skyway and Routes 1 and 9 were all reopened before 6 p.m. Saturday evening.

Hazmat crews responded to the scene and neighboring fire departments assisted.

The cause of the fire is under investigation.

Nearby residents were told to close their windows because of the possibly dangerous smoke and fumes. That warning has since been lifted.

The Bayonne Office of Emergency Management said air quality in the area is “well within acceptable levels.”

At the peak of the blaze, officials in New York City cautioned residents they may see or smell smoke.
