UPDATE: A man remains in the ICU Monday after a multi-vehicle crash on Interstate 75 in Catoosa County, which shut down a portion of the road for nearly four hours.
The Georgia State Patrol confirmed a crash between two cars became a pileup as several other vehicles collided with the wreckage.
It happened around 6:00 AM near Cloud Springs Road.

A fourth vehicle struck the wreckage, which then struck a fifth car.
Diaz was transported to Erlanger Medical Center.
