Southern Illinois Airport Authority

The Southern Illinois Airport Authority is a local government-owned entity registered in the System for Award Management (SAM) since 2012, located in Murphysboro, Illinois. As a regional airport authority, the organization focuses on infrastructure development, economic growth, and providing critical aviation-related services to the Southern Illinois region. The airport authority has consistently engaged with federal agencies to secure grant funding for strategic infrastructure improvements, business development, and community economic enhancement initiatives.

Through federal grant awards, the Southern Illinois Airport Authority has received substantial funding from multiple federal agencies, including the Delta Regional Authority, Rural Business Cooperative Services, Rural Utilities Service, and the Economic Development Administration. These grants have supported a diverse range of projects, including hangar expansions at the airport (specifically Hangar 9, which received two separate grants totaling $1,113,985 to add 3,500 square feet of space), rural business development initiatives, and community facility improvements. The organization has also received sub-grant awards, such as a June 2024 reimbursement from the Illinois Department of Transportation for acquiring an Aircraft Rescue and Fire Fighting (ARFF) testing cart. The grant awards have consistently focused on economic development, infrastructure enhancement, and supporting small businesses in rural communities, with performance periods typically ranging from two to three years. The Southern Illinois Airport Authority's grant portfolio demonstrates a strategic approach to leveraging federal funding to drive regional economic growth and airport infrastructure development.
