A tractor-trailer caught fire on I-495 this afternoon (Wednesday), shutting down all southbound lanes at the Route 50 interchange in Merrifield.
The fire appears to have sparked right as the afternoon rush hour was getting underway. The Fairfax County Fire and Rescue Department reported at 4:16 p.m. that it has units on the scene working to extinguish the fire.
“Currently no clue as to how long the entire roadway will be closed,” a fire department spokesperson told FFXnow.
