Districts Impacted
I-64 North Outer Road/Technology Drive Dardenne Creek bridge replacement project
This project is a joint effort between the City of O'Fallon, Great Rivers Greenway, and the Missouri Department of Transportation (MoDOT). The original project scope included a stand alone pedestrian bridge, a parking lot area, and connections to existing path infrastructure in this area. The City and MoDOT determined through the design scoping that it would be more advantageous and economical to rebuild the existing Technology Dr outer road bridge structure. The reconstruction effort will include a 12' wide shared use path facility across the bridge structure. The planned 10' path sections would then be connected to the parking lot area and existing paths as intended with the original scope. This connection is a vital part of the overall regional connectivity for Great Rivers Greenway through St. Charles with ultimate connectivity planned to the Katy Trail.
Project Milestones
WHAT WILL THE TRAFFIC IMPACTS BE?
In order to construct the new bridge further out of the floodplain of Dardenne Creek, the outer road elevation needs to come up 5-6’ for the new bridge which doesn’t allow for temporary staging to maintain traffic, but rather a full closure. This will allow the contractor to work safely and shorten the timeline of construction. Technology traffic will have a signed detour utilizing I-64 between the Highway K and WingHaven interchanges, but local traffic will likely find alternatives that best suit their needs. Once the project is awarded in Summer 2025, there will be additional outreach to the public once a tentative closure schedule is provided by the contractor.
