The Ford Motor Company plans to add about 1,200 jobs at its Chicago, Ill. assembly plant.

Illinois Gov. Pat Quinn and the company are expected to make a formal announcement Tuesday at the factory. Quinn had already told reporters in Chicago on Monday that the 1,200 new jobs were coming to the state.

"Tomorrow, in one day, we're going to get 1,200 new jobs for Illinois," Quinn said at a breakfast event that was unrelated to the Ford announcement.

Ford officials said the company is shifting production of the next generation Explorer sports utility vehicle from Louisville, Ky. to the Chicago plant.

The workers would help build the new downsized, fuel-efficient Ford Explorer starting later this year.

Some of the jobs are expected to go to former Ford employees laid off at other factories. Ford had laid off some 2,000 jobs last year.
