How We Work
Project Overview
Great Rivers Greenway is partnering with the City of St. Peters and community members to plan, design and build an extension of the Dardenne Greenway. This greenway extension was identified through the St. Charles County Greenway Master Plan as a high priority project by county residents and project stakeholders.
This extension is nearly two miles total, and is planned in two segments: the first will improve the existing trail that extends from Mexico Road to the Dardenne Park parking lot on Dew Court, and the second segment will extend from its current endpoint at Dew Court to the Water’s Edge Banquet Center.
Future phases of the project will extend the greenway to Brown Road Park, Sports Center Park, Old Town St. Peters, and the existing trails within 370 Lakeside Park.
Project Location
The existing paved trail between Mexico Rd and Dardenne Park will be improved as part of this greenway expansion project. The other project segment will continue the greenway to the St. Peters Golf Club & Water’s Edge Banquet Center entrance.

Current Status
Construction and improvements to the existing trail between Mexico Road and Dardenne Park will begin the week of August 3, 2026, and will continue through August 2027. (Like all construction projects, weather could impact this timeline.) Work will include removal and replacement of the existing paved trail, installation of a walking and biking bridge and boardwalk, new landscapes with native plants, and the addition of new retaining walls and fences along sections of the greenway. Please reach out to us at info@grgstl.org or 314-436-7009 with any questions or concerns related to construction activities. We’re excited to bring this project to life for you!
