An accident on Interstate 75 south past exit 20 backed up traffic for several hours Wednesday morning. 

Channel 3 has learned that a tractor-trailer was traveling southbound in the left lane and when trying to move into the right lane, struck a Camaro. 

Both vehicles lost control and wound up in the median. 

The crash happened around 6:15 this morning. 

Any injuries or a cause of the accident are unknown at this time.

We are working to gather more information.
