All lanes are blocked on I-75 southbound after a tractor trailer caught on fire.

It happened near exit 188 southbound.

Monroe County Sheriff John Bittick tells us a tractor trailer caught on fire and is now fully engulfed in flames.

Right now they don't know how long the roads are going to be closed.

The driver of that tractor trailer is ok.
Monroe county e-m-a says to avoid the area.
