Bert Plante, a spokesman for the state Forest Fire Service, said the blaze that broke out Monday in Bass River Township is only a few miles from the highway. He said smoke from the blaze could interfere with traffic during Monday evening's rush hour.
"This is going to be very noticeable from the Parkway, and smoke could be a problem there," he said.
Traffic had not been affected as of 5 p.m., said State Police Capt. Gerald Lewis.
The fire forced the evacuation of Bass River State Park, and the flames could jeopardize the park office, Plante said.
About 18 fire trucks are either at the blaze or on their way there.
The fire had burned between 15 to 20 acres as of 5 p.m. Monday, but was expected to grow.
"Unfortunately, because of the nature of the swamp, we can't get to the fire; it's going to have to come to us," Plante said. "It's going to probably be a couple hundred acres when we're done."
