The Grid at Route 31

The Grid, formerly home to Caterpillar Inc.’s manufacturing operations, sits on approximately 350 acres along Route 31 in Montgomery, Illinois. With over 4 million square feet under roof, the site offers flexible opportunities for large and mid-size users alike. The site features four parking lots totaling 3,750 spaces as well as a helipad that is in current standing with the FAA

The site is characterized by its large concrete pads, heavy utility infrastructure, on-site Co-Gen facility, 300,000-gallon water tower supplying all of the site’s water, and on-site wastewater pre-treatment plant.

Located in unincorporated Kendall County, the site is highly adaptable to a variety of users and current zoning (M-2 Heavy Industrial) allows for most industrial, fabrication, production and manufacturing uses. Caterpillar employed over 5,500 people at this location during peak production.
