About 140 firefighters battled the blaze, which broke out just before 7:30 p.m. near Western and Gulf avenues in the Bloomfield section, and high winds caused it to spread quickly.
Firefighters were putting out hotspots until past midnight in the marshes located on the northwestern part of the Island, south of the Goethals Bridge and west of the West Shore Expressway.
The FDNY contained flames, which had reached a 30-foot wide body of water called Old Place Creek.
There were concerns that several businesses on the opposite side of the creek were in jeopardy, but Marine units helped contain the blaze and kept it from spreading. The FDNY used boats to pump water onto the fires from the Arthur Kill.
Firefighters remained on scene overnight to make sure the fire didn't jump the creek and spread to those businesses.
Traffic on the Goethals Bridge was never shut down, but it was stop and go throughout the night due to visibility issues.
One firefighter suffered minor injuries.
