Pat Reilly, from the Burlington County Bridge Commission talks to NBC10 about what caused the fire underneath the Tacony-Palmyra bridge.
Traffic is moving again on the Tacony-Palmyra bridge, after fire closed the bridge for about an hour.
Pat Reilly, from the Burlington County Bridge Commission, called the fire a "freak accident," and explained how it started.
"The wooden bulkheads on the pier below one of our towers must have caught on fire from a spark from an elect rial line," said Reilly.
The fire broke out around 4:30 p.m. at the anchorage of the bridge, which is the base of one of the support beams.
A Camden City Fire boat responded to help put out the fire, because several fire companies couldn't get a good angle to spray water.
