Kraft Foods is planning a $40 million expansion of its Granite City plant operations that could add 30 jobs.

The project would reconfigure the interior of the existing 265,000-square-foot plant to provide additional space, add new equipment and open four new lines to fill Capri Sun pouches, Kraft spokeswoman Joyce Hodel said.

Hodel said the expansion is to add long-term capacity in Kraft's beverage production network. Kraft Foods has completed several expansion projects since taking over the Capri Sun building in 1991. Production capacity was expanded throughout the 1990s and a warehouse added in 2001.

The company would like a stretch of Missouri Avenue in front of the plant to be widened, but won't say the expansion project is dependent on the street work. "We're very likely to make the investment," Hodel said. "We think the road improvement project is beneficial to the area, as well as Kraft. It will improve traffic flow and safety."

Representatives from the city, the Madison County Highways and Bridges Department or the Illinois Department of Transportation could not be reached about the request to widen Missouri Avenue.

The plant produces more than 100 varieties of Capri Sun and Kool-Aid ready-to-drink beverages. The plant and 395,000-square-foot warehouse at 2901 Missouri Ave. employ 410 workers.

In December, Kraft Foods announced a $25 million expansion to Capri Sun production in its Frederick County, Va., plant.
