A startup company plans to assemble automobiles at a Monroe plant, creating up to 1,500 jobs, a Louisiana lawmaker said Monday.

Rep. Jim Fannin, D-Jonesboro, said a formal announcement could come Wednesday from Gov. Bobby Jindal. He would not identify the company but says the vehicles will be its first and will be built at a former Guide Corp. plant.

Fannin says Louisiana won the plant, beating out Mississippi, with incentives built with local funding and money from the state’s economic development “megafund.” He declined to say how much state money was involved, or provide other details, citing confidentiality agreements.

Calls to Jindal’s office and state economic development officials were not immediately returned.
