Cloverleaf Infrastructure Granite City data center

Cloverleaf Infrastructure Granite City data center is an announced data center project in Granite City, IL. One of three linked Metro East campuses Cloverleaf Infrastructure pitched in January 2026 (with Troy, already tracked). Hundreds packed a Granite City forum Feb 9, 2026 and the city paused talks; the America's Central Port district has since been buying land nearby, prompting questions about a future data center site. (Source dated 2026-02-09.) [Reviewed 2026-10-09: verified] Cloverleaf Infrastructure publicly pitched Granite City as one of three linked Metro East data center sites in early 2026; city paused talks in February following public opposition, no formal project application submitted as of April 2026.
