Traffic in Woodbridge was moving slowly after a fire near explosive chemicals caused roadways to be shut down.

Fire crews arrived along Route 9 South this afternoon to ASCO Torch, an acetylene torch company that contains highly flammable chemicals on site.

The flames were burning a building that was near an 18,000-gallon propane tank. Crews eventually brought the flames under control. 

Traffic was being diverted through the Woodbridge Center Mall parking lot while Route 9 South was shut down. Power also had to be shut down by PSE&G to the area, which affected several traffic signals on Main Street.
