Southwestern Illinois is a region built to help businesses operate efficiently, grow strategically, and connect seamlessly. With a central location and robust transportation infrastructure, companies can reach customers and suppliers across the country with ease. Four Class I railroads, the second-largest inland port system in the U.S., and several regional and international airports provide reliable access to domestic and global markets. This connectivity makes it simple to move materials, ship products, and ensure employees are where they need to be.
One of the region’s business differentiators is the Route 3 corridor, a hub of heavy industry that generates over $16 billion in annual revenue and supports more than 220,000 jobs. Manufacturing, logistics, and warehousing employment in this region outpaces that of many competing markets, creating an ecosystem where companies can leverage established supply chains and industry clusters. Businesses also benefit from a labor pool that draws from three states and over 1,000 zip codes, providing the depth and flexibility needed for growth.
Southwestern Illinois offers real cost advantages without compromising capability. Industrial and commercial real estate is more affordable than in larger metro areas, utility and energy costs are lower, and state and local incentives help reduce capital and operational expenses. These benefits allow companies to reinvest in growth, workforce development, and innovation while maintaining a competitive edge.
A skilled and prepared workforce sets the region apart. Local colleges, universities, and training programs align with the needs of manufacturing, logistics, and other key industries, ensuring employees are equipped with relevant experience and certifications. With access to talent across state lines and a range of apprenticeship and technical training programs, businesses can scale their workforce efficiently and sustainably.
Beyond infrastructure and workforce, Southwestern Illinois provides a supportive environment for business. Local governments and economic development organizations guide projects from site selection to expansion, and regional partners help companies navigate permitting, incentives, and community engagement. For those seeking the best places to start a business, Southwestern Illinois makes it straightforward and smart to get started.
