Great Rivers Greenway is the largest organization of its kind in the nation, working to build a cleaner, greener, safer and more connected St. Louis region.

Arcturis managed the regional planning process and design development components of the citizen-driven regional plan, which covers 1,200 square miles including St. Louis City, St. Louis County, and St. Charles County, MO.

As the lead firm in the GRG project, Arcturis works with sub-consultants and Great Rivers Greenway to provide the design framework for economic, social, and environmental benefits across St. Louis and the surrounding area.
