Project Overview
The City of O’Fallon and Great Rivers Greenway are partnering to build a new trailhead for the Dardenne Greenway at Technology Drive with a parking lot and connections to nearby trails. There will also be benches, wayfinding signage, and native plants and landscaping. The new trailhead will connect greenway users to the Dardenne Greenway, as well as existing City of O’Fallon trails and a trail within the neighboring Barathaven property. At the same time, the Missouri Department of Transportation will be completely rebuilding the Technology Drive Outer Road bridge structure and adding a twelve foot wide, separated path for walking and biking. Eventually, this trailhead will serve a future walking and biking crossing at I-64 linking the Dardenne and Busch Greenways.
Project Location
The Trailhead at Technology Drive will be located in the City of O’Fallon, where the existing Dardenne Greenway currently ends at Technology Drive/I-64. The trailhead will be just northwest of the St. Charles Community College Dardenne Campus.
