Ford is going to make a huge announcement Thursday expected to impact thousands of Louisville workers.

Ford is expected to announce that it's revamping some U.S. facilities, including the Louisville Assembly Plant and the Kentucky Truck Plant.  The automaker also plans to increase production of small cars.

The move could shift production of the Expedition and the Lincoln Navigator to the Truck Plant.

That would make way for the Assembly Plant to produce smaller vehicles.  Ford executives are expected to discuss the future of the company at a press conference Thursday morning.
