Gov. Martha Layne Collins said through an aide that Toyota officials had confirmed that their multimillion-dollar automobile assembly plant will be built in Scott County. The site is reportedly a 1,600-acre tract of flat farmland near the college town of Georgetown. Toyota officials are expected to make a formal announcement Wednesday. The plant reportedly will cost $500 million to $600 million and employ about 2,000 workers to assemble 200,000 cars a year.
