Area	Approx. 200 square miles

Confluence Greenway is a regional network of parks, trails, conservation areas, and historic sites centered on the meeting of the Mississippi River and the Missouri River near St. Louis. The Greenway links municipal parks, federal lands, state parks, non‑profit preserves, and urban waterfronts to provide recreational access and ecological corridors across parts of Missouri and Illinois. Planned and implemented through partnerships among local governments, state agencies, federal agencies, non‑profits, and civic organizations, the Greenway connects heritage landmarks, wildlife habitats, and trail systems.

History

Origins trace to regional planning initiatives in the 1990s involving the Great Rivers Greenway District, East‑West Gateway Council of Governments, Metropolitan St. Louis Sewer District, National Park Service, and the U.S. Army Corps of Engineers. Early proponents included leaders from City of St. Louis, St. Louis County, Madison County, Illinois, and St. Clair County, Illinois collaborating with advocacy groups such as the Confluence Partnership, Mississippi River Basin Alliance, and The Nature Conservancy. Influential projects and funding sources involved the Transportation Equity Act for the 21st Century, the Intermodal Surface Transportation Efficiency Act, and grants from the National Endowment for the Arts and the William T. Kemper Foundation. Planning documents referenced regional strategies by American Rivers, Rails-to-Trails Conservancy, Trust for Public Land, and academic studies from Washington University in St. Louis and Saint Louis University. Implementation engaged federal programs including the Federal Highway Administration, the U.S. Fish and Wildlife Service, and state agencies such as the Missouri Department of Natural Resources and the Illinois Department of Natural Resources.

Geography and Route

The Greenway spans river corridors and floodplain landscapes between Alton, Illinois and Hannibal, Missouri, including segments through Chouteau Island, Columbia Bottom Conservation Area, Castlewood State Park, Marlyville Park, and Sioux Passage. The route incorporates existing trail systems like the Katy Trail State Park, the MCT Confluence Trail, the Lewis and Clark Trail, and urban promenades along Gateway Arch National Park near Downtown St. Louis. Key river crossings and nodes link infrastructure such as the McKinley Bridge, Eads Bridge, Chain of Rocks Bridge, and Hannibal Bridge with adjacent conservation properties including Boschert Greenway, Belvoir Farms, Cahokia Mounds State Historic Site, and Kaskaskia River State Wildlife Area.

Ecology and Conservation

The Greenway protects riparian habitats, bottomland forests, wetlands, and migratory corridors for species associated with the Mississippi Flyway. Conservation partners include Missouri Department of Conservation, Illinois Audubon Society, Audubon Missouri, U.S. Fish and Wildlife Service, Conservation Federation of Missouri, and local land trusts like the Landmarks Association of St. Louis. Native flora and fauna documented across sites include bottomland oaks, cottonwoods, silver maples, Bald eagle nesting sites monitored by U.S. Fish and Wildlife Service biologists, riverine mussels studied by researchers at Missouri Botanical Garden, and fish species managed by state agencies and researchers at University of Missouri. Wetland restoration projects have drawn expertise from The Conservation Fund, Parks for People, EPA Region 7, and academic partners including University of Illinois Urbana‑Champaign.

Recreation and Amenities

The Greenway offers multiuse trails, canoe and kayak access, birdwatching platforms, interpretive centers, picnic areas, and equestrian routes. Major trailheads connect to facilities operated by Great Rivers Greenway District, Madison County Transit, Metro Transit (St. Louis), St. Louis County Parks, Illinois Department of Natural Resources, and municipal park departments in Alton, Illinois and West Alton, Missouri. Recreational programming features guided tours by National Park Service, educational workshops hosted by Missouri Department of Conservation, volunteer events coordinated with Missouri Botanical Garden Volunteers, and interpretive signage developed with input from Historic St. Louis, Inc..

Management and Governance

Management is a cooperative framework involving the Great Rivers Greenway District, East‑West Gateway Council of Governments, U.S. Army Corps of Engineers, National Park Service, state agencies (Missouri Department of Natural Resources, Illinois Department of Natural Resources), county park boards, and non‑profit partners including The Nature Conservancy, Trust for Public Land, and the Confluence Partnership. Governance models utilize memoranda of understanding among City of St. Louis, St. Louis County, Madison County, Illinois, and federal agencies such as the Federal Emergency Management Agency for floodplain management. Funding and stewardship draw on grants from National Endowment for the Humanities, corporate philanthropy from regional companies like Boeing, Anheuser‑Busch, and foundation support from E. Rhodes and Leona B. Carpenter Foundation.

Cultural and Historical Sites

The Greenway connects significant cultural and historical places including Gateway Arch National Park, Lewis and Clark State Historic Site, Cahokia Mounds State Historic Site, Mark Twain Boyhood Home and Museum, Fort Bellefontaine Historic Site, Old Chain of Rocks Bridge, Rosati's Pizza districts, Laclede's Landing, and numerous Native American heritage sites tied to the Mississippian culture. Interpretive collaborations have involved historians from Missouri Historical Society, curators at the St. Louis Art Museum, and archivists at the State Historical Society of Missouri.

Development and Future Plans

Future plans emphasize trail expansions, habitat restoration, climate resilience projects, and increased access through partnerships with Metropolitan St. Louis Sewer District for green infrastructure, with technical input from Army Corps of Engineers. Proposed initiatives include multimodal connections to Amtrak, transit‑oriented access with MetroLink (St. Louis), expanded active transportation links promoted by Rails-to-Trails Conservancy, and urban revitalization projects coordinated with City of St. Louis Planning Commission and Madison County Transit. Long‑range strategies reference regional sustainability goals advanced by East‑West Gateway Council of Governments and civic initiatives by St. Louis Economic Development Partnership.
