( Butler County ) - Emergency crews are responding to a tractor trailer fire on I-75. It happened just after 2:30 on the southbound side about a mile before 129.

As of 3 o'clock, both the northbound and southbound lanes are completely shut down. 

UPDATE: First responders say all lanes re-opened at about 8:30pm. The crash apparently happened when the northbound semi somehow had its trailer flip into the southbound lanes. We're still waiting on a full statement from investigators.
