Looking for sites that have been pre-qualified for major industrial investment projects?  The Illinois Super Sites meet standards typically required for very large industrial projects.  Thus, if your company is or may be in the market for a 250+ acre site with high capacity utilities, rail service and interstate access, check these sites out.  Information is included that will expedite the site selection review process.
