The overall Centennial Greenway is a 14 - mile link between St. Louis and St. Charles counties and the City of St. Louis, from Forest Park to Creve Coeur Park. The Greenway is meant to create new ways to experience the metropolitan area with a safe and dynamic means of accessing diverse urban and rural adventures. Cole was responsible for civil design and utility relocations for Great River Greenway's District trail system from Forest Park at Skinker Boulevard, through the Washington University Campus to a connection with the existing trail system north of Delmar Boulevard.
