The Mars Wrigley company caught much of Chicago by surprise when it announced plans last week to close its historic plant in the city’s Galewood neighborhood.
The Spanish Revival-designed complex at 2019 N. Oak Park Ave. will stop churning out M&Ms, Twix, Snickers, Milky Way and other candies in two years, according to its owner, Mars Wrigley Confectionery. About 280 people work there.
